Can the server get a long-lived access token with the code in `signedRequest`? - facebook

Is the code property of authResponse.signedRequest (in the Facebook JavaScript API) useful? I'm generating one like this:
FB.login({ scope: "email" }, function(r) {
console.log([
function(d){ return d.split('.')[1]; },
function(d){ return atob(d.replace('-', '+').replace('_', '/')); },
JSON.parse,
function(d){ return d.code; }
].reduce(
function(acc, f) { return f(acc); },
r.authResponse.signedRequest
));
});
The docs say this:
code: an OAuth Code which can be exchanged for a valid user access token via a subsequent server-side request
…but that link redirects to Facebook Login home page. I found the /oauth/access_token endpoint documented here, but it requires a redirect_uri parameter, and there isn't one in this case.

As CBroe suggested, the code in this response appears to have already been used by the JavaScript SDK to create a short-lived token.

I know it's a bit of a necro-bump, but for anyone else who stumbles upon this...
You can POST the code to:
https://graph.facebook.com/oauth/access_token
In the form body, you want:
client_id: your_app_client_id
client_secret: you_app_client_secret
grant_type: "authorization_code"
redirect_uri: ""
code: code_from_signed_request
The blank redirect_uri is the key. You must supply a blank string ... omitting the field doesn't work.
Since you need to supply your client secret, you don't want to do this client-side. Send the code to some method on your server to do it, and return the access code to your client.

Generate access token using JWT

I've been given access to an okta token endpoint. I would like to use this service to request a token. I was given a url, client id, client secret, scope and grant type. I can use postman to make a POST call to the url (/v1/token) and pass the above info (client id, client secret, scope and grant type) and I get an access token back.
I can easily make this call in java with RestTemplate or equivalent, but I would like to use an API that would manage the token for me.
I've found JJWT. All the examples I see out there show me how to create a JWT using JJWT. What I would like to do is to get my access token, but I'm not sure how to do that. I mean i get that JJWT is an API to create JWT, but then how can I use the JWT to get my access token?
Any help/clarification/direction is much appreciated.
We using JWT with the node.js, to create new Token jwt.sign(data, key) takes at least to an argument, the fist must be some credential like userId, email..., the second will be key to verify later. to verify the token is it valid we use jwt.verify(), the first argument is token (where the jwt.sing() give you) and the second is the key (where you provide when creating);
example:
Creating JWT token:
var jwt = require('jsonwebtoken');
cosnt token = jwt.sign({ email: 'test#test.com', userId: '993333' }, 'secretkey');
verifying Token:
try {
const decodedToken = jwt.verify(token, 'secretkey');
}
catch(err) {
throw new Error(err)
}
// once verified
conosole.log(decodedToken)
I found this post how to create and verify token using java, thanks!

Not able to set generated access_token in request object

I am authenticating user with the help of JWT token and #nestjs/passport library. I am able to successfully generate and return the access token but stuck at how to set it in the req object. So that I can validate other api routes until user logs out
Below code shows how I generated the access_token and returned to the calling point
let payload = { username: user.email, sub: user.id }
const accessToken = this.jwtService.sign(payload);
return {
expires_in: 3600,
access_token: accessToken,
status: 200
}
I am getting the access_token correctly. I verified generated access_token using https://jwt.io/ debugger and results were correct.
Can someone help me in setting up the req object with access_token?
There is multiple way you could send JWT token in your requests. If you have followed this tutorial: https://docs.nestjs.com/techniques/authentication, you are using passport-jwt library for JWT. One way is through header if you don't set auth schema it will be this one:
Authorization: JWT <-HERE YOU SHOULD INSERT TOKEN->
If you set authSchema to be bearer, then you could use this header like this:
Authorization: BEARER <-HERE YOU SHOULD INSERT TOKEN->
Except for that you can put your JWT into URL like this:
https://example.com/me?auth_token=<-HERE YOU SHOULD INSERT TOKEN->
Or in object body that you are sending with property named auth_token:
https://example.com/me
Body:
{
auth_token: <-HERE YOU SHOULD INSERT TOKEN->
}
You can find this in the source code of passport-jwt in this file.

The "state" param from the URL and session do not match

In facebook documantion
require('include/facebook/autoload.php'); //SDK directory
$fb = new Facebook\Facebook([
'app_id' => '***********',
'app_secret' => '***********************'
]);
$helper = $fb->getRedirectLoginHelper();
$permissions = ['email', 'public_profile']; // optional
$loginUrl = $helper->getLoginUrl('http://www.meusite.com.br/login-callback.php', $permissions);
When direct it to the url $loginUrl, the return is:
Facebook SDK returned an error: Cross-site request forgery validation failed. The "state" param from the URL and session do not match
I had the same error.
The problem occurred because I did getLoginUrl(...) before getAccessToken()
So rid of getLoginUrl(...) in redirected URL and code should works.
I had the same issue and for me that error was occurring because I did not put session_start(); in my login.php page code before calling getLoginUrl(..) and also at the top of login-callback.php page.
Just put session_start(); in your "login" page and "login-callback" page and it will work surely just like it is working for me now.
There could be 2 reason for this error:
you didn't call session_start(); before getLoginUrl call
You executed getLoginUrl again in login-callback.php, so state value regenerated and mismatched with the redirected value
Possible Fixes : I used the following configuration settings .
Enable WebAuthLogin under the advanced tab . Provide the url in the WebAuthLogin settins as same as that you provide in $loginUrl ;
For example if you use $loginUrl as https://example.com/ use that same in the WebAuthlogin Url
$loginUrl = $helper->getLoginUrl('https://example.com/', $permissions);
This problem occures also in case that you generate 2 or more login links on the same page (e.g. one for login and other for registration - even both point to the same url, they have just different labels).
Facebook SDK creates/updates $_SESSION[FBRLH_state] for each new generated loginURL. So if there are 2 generated URLs (using $helper->getLoginUrl()) then the $_SESSION[FBRLH_state] is 2-times rewritten and valid only for the last generated URL. Previous login URL becomes invalid. It means that it is not possible to generate 2 valid loginURLs. In case that 2 same URLs are generated then return the first one and avoid call of Facebook SDK for generation of second one.
I had the same problem.
The reason for this error is because --->
When "$helper->getLoginUrl" calls, it create a session variable "FB_State", and this is something to FB uses to match the token. Every-time getLoginUrl calls, it create new state. Then after user authorized and redirect back, if you codes cannot detect this event and re-run "$helper->getLoginUrl", then this error will occur.
The solution ->
refine your coding, stop run "$helper->getLoginUrl" again if authorized.
if you already rerun, then set the session variable for the token to NULL if you have, then User can re-authorize again.
when user tries re-authorize, they can remove the authorized APP once or you need to generate new link with "$helper->getReRequestUrl"
Yet, token has be called by "getAccessToken()" before the "$helper->getLoginUrl" or "$helper->getReRequestUrl" runs.
Good Luck!!!!!
Finally, looking into FB code, I discovered that the problem "Cross-site request forgery validation failed. Required param “state” missing" and similars are caused by PHP variable $_SESSION['FBRLH_state'] that for some "strange" reason when FB call the login-callback file.
To solve it I store this variable "FBRLH_state" AFTER the call of function $helper->getLoginUrl(...). Is very important to do only after the call of this function due to is inside this function when the variable $_SESSION['FBRLH_state'] is populated.
Below an example of my code in the login.php:
$uri=$helper->getLoginUrl($uri, $permissions);
foreach ($_SESSION as $k=>$v) {
if(strpos($k, "FBRLH_")!==FALSE) {
if(!setcookie($k, $v)) {
//what??
} else {
$_COOKIE[$k]=$v;
}
}
}
var_dump($_COOKIE);
And in the login-callback.php before calling all FB code:
foreach ($_COOKIE as $k=>$v) {
if(strpos($k, "FBRLH_")!==FALSE) {
$_SESSION[$k]=$v;
}
}
Last, but not least, remember also to include code for PHP session so..
if(!session_id()) {
session_start();
}
...
...
...
...
<?php session_write_close() ?>
I hope this response can help you to save 8-10 hours of work :)
Bye, Alex.
This issue was a bit confusing for me, because I had to change a line at the facebook src file:
src/Facebook/Helpers/FacebookRedirectLoginHelper.php
at the function: "validateCsrf" like this:
if ($result !== 0) {
throw new FacebookSDKException('Cross-site request forgery validation failed. The "state" param from the URL and session do not match.');
}
And change it into:
if ($result === 0) {
throw new FacebookSDKException('Cross-site request forgery validation failed. The "state" param from the URL and session do not match.');
}
I don't know if this makes a violation to the facebook SDK security, so I truly opened to any exlanation or recommendation for this answer.
You may also make the following changes at the facebook app manager:
add your site and callback-url into your facebook app account at:
setting->advanced:Valid OAuth redirect URIs
Don't forget to add another url with slash (/) at the end of each url and check all 4 checkboxes at Client OAuth Settings.
I had the same error. Are you using 1 file or 2? I was trying to get by using 1 file but my error was resolved when I split into login.php & fb-callback.php as the documentation recommended. My sessions were being re-written so the state was never saved properly.
Good luck!
Happens when the session in missing a needed variable.
might be caused by several things.
In my case I left the "www" out of the callback URL
You could actually be parsing the data from another domain... for example:
website.com is different from www .website.com
If you're parsing data from http ://website.com/login.php to http://www.website.com/fb-callback.php this would be a cross-domain problem and the error you are receiving would be because of that....
http ://website.com and http ://www.website.com are the same but the script identifies them as different..... hope that gives insight to the problem.

Unable to get a long term access token using facebook graph api

I'm new to integrating facebook into the websites I'm working on and trying to get a long term access token by following the instructions here: https://developers.facebook.com/docs/facebook-login/access-tokens/
Even when using the Graph API Explorer here: https://developers.facebook.com/tools/explorer/
I enter the following and populate it with my AppID and AppSecret and current token I get when I press Get Access Token...
GET /oauth/access_token?
grant_type=fb_exchange_token&
client_id={app-id}&
client_secret={app-secret}&
fb_exchange_token={short-lived-token}
I get the return
{ "error": "Invalid response" }
Can someone elaborate on what I might be doing wrong, or the steps in greater detail that works for you in acquiring this long term token.
I've tried to follow what's happening in this thread Facebook Page Access Tokens - Do these expire? with no more success. Any help would be greatly appreciated.
Thanks for your time and help.
Cheers,
-Ryan
You can't get the long-lived user token using the Graph API Explorer. You have to make a GET request to:
https://graph.facebook.com/oauth/access_token?
grant_type=fb_exchange_token&
client_id={app-id}& client_secret={app-secret}& fb_exchange_token={short-lived-token}
You can check it in the browser.
If you need the page access token, you can have a never expiring token. Check out the accepted answer here: What are the Steps to getting a Long Lasting Token For Posting To a Facebook Fan Page from a Server
So I thought I'd revisit this and provide the documentation I wrote that will hopefully help someone else get this happening!
ONE. Create Application
Create an application associated with the user of the page you want to have access to.
TWO. Get Required Pieces of Info
After creating an App we should have two key pieces of info:
App ID: AAAAA (should be about ~15 characters long)
App Secret: BBBBB (should be about ~32 characters long)
With these by going to https://developers.facebook.com/tools/explorer
Making sure to select the correct Application from the Dropdown Box at the top.
Click on Get Access Token and get a ‘fresh’ token.
Here you'll need to select appropriate permissions for your specific app's purpose.
CCCCC (should be ~200 characters long)
THREE. Get Long Life Token (2 Month)
You should then have the pieces of info needed to run the query to get a long-term (2 month) token:
https://graph.facebook.com/oauth/access_token?grant_type=fb_exchange_token&client_id={app-id}& client_secret={app-secret}& fb_exchange_token={short-lived-token}
Replace {app-id}, {app-secret} and {short-lived-token} with the three bits of info you’ve taken note of so far.
You should get a request like the following:
https://graph.facebook.com/oauth/access_token?%20grant_type=fb_exchange_token&%20client_id=AAAAA&%20client_secret=BBBBB&%20fb_exchange_token=CCCCC
Place this query into the url bar of an internet browser. You should get a response in the window that looks something like the following:
access_token=DDDDD&expires=5184000
DDDDD (should be ~200 characters long)
FOUR. Test Token (Part 1)
If you enter the highlighted part into the input on the following debug site:
https://developers.facebook.com/tools/debug/
It should give you an expiry of approximately 2 months.
FIVE. Get Non Expiring Page Token
Now taking note of this new long-live-token we’ll use this to get a token that doesn’t expire, unless the associated application is removed from a user’s access or deleted.
We use either the page name or preferably page-id when making the request:
You can get your facebook page id using something like http://findmyfacebookid.com/
We'll refer to your page id as EEEEE
https://graph.facebook.com/{page-id}/?fields=access_token&access_token={long-live-token}
You should get a request like the following:
https://graph.facebook.com/EEEEE/?fields=access_token&access_token=DDDDD
This will return something like the following:
{
"access_token": "FFFFF",
"id": "131062838468"
}
FFFFF (should be ~200 characters long)
SIX. Test Token (Part 2)
Take the highlighted part and enter it into the debug page and you should get something that shows the token never expires and you’ve been successful in acquiring your never expiring page token.
SEVEN. High Five!
Sorry for the long list of how to achieve this, but I find it better to give the whole process instead of just a small snippet. Let me know if you find this helpful or you have a better way of achieving any of the steps.
Facebook PHP SDK has already implemented method to get long-lived token using short-lived token, after login successfully and got the short-lived token, simple calling
$result = $facebook->setExtendedAccessToken();
if $result is null, it means you got the long-lived access token.
client side
if (response.status === 'connected') {
{
event.preventDefault();
FB.login(function (response) {
if (response.authResponse) {
var profileId = response.authResponse.userID;
var accessToken = response.authResponse.accessToken;
var e = response.authResponse.accessToken;
document.getElementById('token').innerHTML = e;
var profileName = "";
var pagesList = "";
var isPage = 0;
var type = "fb";
$.ajax({
url: "WebService1.asmx/getlonToken",
type: "POST",
dataType: 'json',
data: '{accessToken:"' + accessToken + '"}',
contentType: "application/json; charset=utf-8",
async: true,
success: function (response) {
accessToken = response.d;
document.getElementById('status').innerHTML = accessToken;
},
error: function (e) {
alert('Error' + e);
}
});
}
}, { scope: 'user_about_me,friends_about_me,user_activities,friends_activities,user_birthday,friends_birthday,user_education_history,friends_education_history,user_events,friends_events,user_groups,friends_groups,user_hometown,friends_hometown,user_interests,friends_interests,user_likes,friends_likes,user_location,friends_location,user_notes,friends_notes,user_photos,friends_photos,user_relationships,friends_relationships,user_relationship_details,friends_relationship_details,user_status,friends_status,user_videos,friends_videos,user_website,friends_website,email,manage_pages,publish_stream,read_stream,read_page_mailboxes,read_insights, read_mailbox' });
}
Server side
[WebMethod]
public string getlonToken(string accessToken)
{
var fb = new FacebookClient(accessToken);
dynamic result = fb.Get("oauth/access_token", new
{
client_id = 123,
client_secret = "123fff45",
grant_type = "fb_exchange_token",
fb_exchange_token = accessToken,
scope = "user_about_me,friends_about_me,user_activities,friends_activities,user_birthday,friends_birthday,user_checkins,friends_checkins,user_education_history,friends_education_history,user_events,friends_events,user_groups,friends_groups,user_hometown,friends_hometown,user_interests,friends_interests,user_likes,friends_likes,user_location,friends_location,user_notes,friends_notes,user_photos,friends_photos,user_relationships,friends_relationships,user_relationship_details,friends_relationship_details,user_religion_politics,friends_religion_politics,user_status,friends_status,user_videos,friends_videos,user_website,friends_website,email,manage_pages,publish_stream,read_stream,read_page_mailboxes,read_insights,ads_management"
});
fb.AccessToken = (string)result["access_token"];
return fb.AccessToken;
}
}
You can generate Short-Lived Token from Graph API Explorer.
Then you can extend it in Long-Lived Token from Access Token Debugger.
I do this every time.

Not receiving Google OAuth refresh token

I want to get the access token from Google. The Google API says that to get the access token, send the code and other parameters to token generating page, and the response will be a JSON Object like :
{
"access_token" : "ya29.AHES6ZTtm7SuokEB-RGtbBty9IIlNiP9-eNMMQKtXdMP3sfjL1Fc",
"token_type" : "Bearer",
"expires_in" : 3600,
"refresh_token" : "1/HKSmLFXzqP0leUihZp2xUt3-5wkU7Gmu2Os_eBnzw74"
}
However, I'm not receiving the refresh token. The response in my case is:
{
"access_token" : "ya29.sddsdsdsdsds_h9v_nF0IR7XcwDK8XFB2EbvtxmgvB-4oZ8oU",
"token_type" : "Bearer",
"expires_in" : 3600
}
The refresh_token is only provided on the first authorization from the user. Subsequent authorizations, such as the kind you make while testing an OAuth2 integration, will not return the refresh_token again. :)
Go to the page showing Apps with access to your account:
https://myaccount.google.com/u/0/permissions.
Under the Third-party apps menu, choose your app.
Click Remove access and then click Ok to confirm
The next OAuth2 request you make will return a refresh_token (providing that it also includes the 'access_type=offline' query parameter.
Alternatively, you can add the query parameters prompt=consent&access_type=offline to the OAuth redirect (see Google's OAuth 2.0 for Web Server Applications page).
This will prompt the user to authorize the application again and will always return a refresh_token.
In order to get the refresh token you have to add both approval_prompt=force and access_type="offline"
If you are using the java client provided by Google it will look like this:
GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
HTTP_TRANSPORT, JSON_FACTORY, getClientSecrets(), scopes)
.build();
AuthorizationCodeRequestUrl authorizationUrl =
flow.newAuthorizationUrl().setRedirectUri(callBackUrl)
.setApprovalPrompt("force")
.setAccessType("offline");
I'd like to add a bit more info on this subject for those frustrated souls who encounter this issue. The key to getting a refresh token for an offline app is to make sure you are presenting the consent screen. The refresh_token is only returned immediately after a user grants authorization by clicking "Allow".
The issue came up for me (and I suspect many others) after I'd been doing some testing in a development environment and therefore already authorized my application on a given account. I then moved to production and attempted to authenticate again using an account which was already authorized. In this case, the consent screen will not come up again and the api will not return a new refresh token. To make this work, you must force the consent screen to appear again by either:
prompt=consent
or
approval_prompt=force
Either one will work but you should not use both. As of 2021, I'd recommend using prompt=consent since it replaces the older parameter approval_prompt and in some api versions, the latter was actually broken (https://github.com/googleapis/oauth2client/issues/453). Also, prompt is a space delimited list so you can set it as prompt=select_account%20consent if you want both.
Of course you also need:
access_type=offline
Additional reading:
Docs: https://developers.google.com/identity/protocols/oauth2/web-server#request-parameter-prompt
Docs: https://developers.google.com/identity/protocols/oauth2/openid-connect#re-consent
Discussion about this issue: https://github.com/googleapis/google-api-python-client/issues/213
I searched a long night and this is doing the trick:
Modified user-example.php from admin-sdk
$client->setAccessType('offline');
$client->setApprovalPrompt('force');
$authUrl = $client->createAuthUrl();
echo "<a class='login' href='" . $authUrl . "'>Connect Me!</a>";
then you get the code at the redirect url
and the authenticating with the code and getting the refresh token
$client()->authenticate($_GET['code']);
echo $client()->getRefreshToken();
You should store it now ;)
When your accesskey times out just do
$client->refreshToken($theRefreshTokenYouHadStored);
This has caused me some confusion so I thought I'd share what I've come to learn the hard way:
When you request access using the access_type=offline and approval_prompt=force parameters you should receive both an access token and a refresh token. The access token expires soon after you receive it and you will need to refresh it.
You correctly made the request to get a new access token and received the response that has your new access token. I was also confused by the fact that I didn't get a new refresh token. However, this is how it is meant to be since you can use the same refresh token over and over again.
I think some of the other answers assume that you wanted to get yourself a new refresh token for some reason and sugggested that you re-authorize the user but in actual fact, you don't need to since the refresh token you have will work until revoked by the user.
Rich Sutton's answer finally worked for me, after I realized that adding access_type=offline is done on the front end client's request for an authorization code, not the back end request that exchanges that code for an access_token. I've added a comment to his answer and this link at Google for more info about refreshing tokens.
P.S. If you are using Satellizer, here is how to add that option to the $authProvider.google in AngularJS.
In order to get the refresh_token you need to include access_type=offline in the OAuth request URL. When a user authenticates for the first time you will get back a non-nil refresh_token as well as an access_token that expires.
If you have a situation where a user might re-authenticate an account you already have an authentication token for (like #SsjCosty mentions above), you need to get back information from Google on which account the token is for. To do that, add profile to your scopes. Using the OAuth2 Ruby gem, your final request might look something like this:
client = OAuth2::Client.new(
ENV["GOOGLE_CLIENT_ID"],
ENV["GOOGLE_CLIENT_SECRET"],
authorize_url: "https://accounts.google.com/o/oauth2/auth",
token_url: "https://accounts.google.com/o/oauth2/token"
)
# Configure authorization url
client.authorize_url(
scope: "https://www.googleapis.com/auth/analytics.readonly profile",
redirect_uri: callback_url,
access_type: "offline",
prompt: "select_account"
)
Note the scope has two space-delimited entries, one for read-only access to Google Analytics, and the other is just profile, which is an OpenID Connect standard.
This will result in Google providing an additional attribute called id_token in the get_token response. To get information out of the id_token, check out this page in the Google docs. There are a handful of Google-provided libraries that will validate and “decode” this for you (I used the Ruby google-id-token gem). Once you get it parsed, the sub parameter is effectively the unique Google account ID.
Worth noting, if you change the scope, you'll get back a refresh token again for users that have already authenticated with the original scope. This is useful if, say, you have a bunch of users already and don't want to make them all un-auth the app in Google.
Oh, and one final note: you don't need prompt=select_account, but it's useful if you have a situation where your users might want to authenticate with more than one Google account (i.e., you're not using this for sign-in / authentication).
1. How to get 'refresh_token' ?
Solution: access_type='offline' option should be used when generating authURL.
source : Using OAuth 2.0 for Web Server Applications
2. But even with 'access_type=offline', I am not getting the 'refresh_token' ?
Solution: Please note that you will get it only on the first request, so if you are storing it somewhere and there is a provision to overwrite this in your code when getting new access_token after previous expires, then make sure not to overwrite this value.
From Google Auth Doc : (this value = access_type)
This value instructs the Google authorization server to return a
refresh token and an access token the first time that your application
exchanges an authorization code for tokens.
If you need 'refresh_token' again, then you need to remove access for your app as by following the steps written in Rich Sutton's answer.
I'm using nodejs client for access to private data
The solution was add the promp property with value consent to the settings object in oAuth2Client.generateAuthUrl function.
Here is my code:
const getNewToken = (oAuth2Client, callback) => {
const authUrl = oAuth2Client.generateAuthUrl({
access_type: 'offline',
prompt: 'consent',
scope: SCOPES,
})
console.log('Authorize this app by visiting this url:', authUrl)
const rl = readline.createInterface({
input: process.stdin,
output: process.stdout,
})
rl.question('Enter the code from that page here: ', (code) => {
rl.close()
oAuth2Client.getToken(code, (err, token) => {
if (err) return console.error('Error while trying to retrieve access token', err)
oAuth2Client.setCredentials(token)
// Store the token to disk for later program executions
fs.writeFile(TOKEN_PATH, JSON.stringify(token), (err) => {
if (err) return console.error(err)
console.log('Token stored to', TOKEN_PATH)
})
callback(oAuth2Client)
})
})
}
You can use the online parameters extractor to get the code for generate your token:
Online parameters extractor
Here is the complete code from google official docs:
https://developers.google.com/sheets/api/quickstart/nodejs
I hope the information is useful
Setting this will cause the refresh token to be sent every time:
$client->setApprovalPrompt('force');
an example is given below (php):
$client = new Google_Client();
$client->setClientId($client_id);
$client->setClientSecret($client_secret);
$client->setRedirectUri($redirect_uri);
$client->addScope("email");
$client->addScope("profile");
$client->setAccessType('offline');
$client->setApprovalPrompt('force');
For me I was trying out CalendarSampleServlet provided by Google. After 1 hour the access_key times out and there is a redirect to a 401 page. I tried all the above options but they didn't work. Finally upon checking the source code for 'AbstractAuthorizationCodeServlet', I could see that redirection would be disabled if credentials are present, but ideally it should have checked for refresh token!=null. I added below code to CalendarSampleServlet and it worked after that. Great relief after so many hours of frustration . Thank God.
if (credential.getRefreshToken() == null) {
AuthorizationCodeRequestUrl authorizationUrl = authFlow.newAuthorizationUrl();
authorizationUrl.setRedirectUri(getRedirectUri(req));
onAuthorization(req, resp, authorizationUrl);
credential = null;
}
Using offline access and prompt:consent worked well to me:
auth2 = gapi.auth2.init({
client_id: '{cliend_id}'
});
auth2.grantOfflineAccess({prompt:'consent'}).then(signInCallback);
In order to get new refresh_token each time on authentication the type of OAuth 2.0 credentials created in the dashboard should be "Other". Also as mentioned above the access_type='offline' option should be used when generating the authURL.
When using credentials with type "Web application" no combination of prompt/approval_prompt variables will work - you will still get the refresh_token only on the first request.
To get a refresh token using postman, here is an example of the configurations

now google had refused those parameters in my request (access_type, prompt)... :( and there is no "Revoke Access" button at all. I'm frustrating because of getting back my refresh_token lol
UPDATE:
I found the answer in here :D you can get back the refresh token by a request
https://developers.google.com/identity/protocols/OAuth2WebServer
curl -H "Content-type:application/x-www-form-urlencoded" \
https://accounts.google.com/o/oauth2/revoke?token={token}
The token can be an access token or a refresh token. If the token is an access token and it has a corresponding refresh token, the refresh token will also be revoked.
If the revocation is successfully processed, then the status code of the response is 200. For error conditions, a status code 400 is returned along with an error code.

My solution was a bit weird..i tried every solution i found on internet and nothing. Surprisely this worked: delete the credentials.json, refresh, vinculate your app in your account again. The new credentials.json file will have the refresh token. Backup this file somewhere.
Then keep using your app until the refresh token error comes again. Delete the crendetials.json file that now is only with an error message (this hapenned in my case), then paste you old credentials file in the folder, its done!
Its been 1 week since ive done this and had no more problems.
Adding access_type=offline to the authorisation Google authorisation URL did the trick for me. I am using Java and Spring framework.
This is the code that creates the client registration:
return CommonOAuth2Provider.GOOGLE
.getBuilder(client)
.scope("openid", "profile", "email", "https://www.googleapis.com/auth/gmail.send")
.authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
.authorizationUri("https://accounts.google.com/o/oauth2/v2/auth?access_type=offline")
.clientId(clientId)
.redirectUriTemplate("{baseUrl}/{action}/oauth2/code/{registrationId}")
.clientSecret(clientSecret)
.build();
The important part here is the authorization URI, to which ?access_type=offline is appended.
