I went to https://developers.facebook.com/tools/explorer?method=GET, set up there ID of my Facebook page, set up there the correct permission for posting statuses on my FB timeline and generated access token.
Then I wanted to extend this short-live token on the long-term (60 days long valid token). So I did following - I put this URL to the browser:
https://graph.facebook.com/oauth/access_token?client_id=APP_ID_OF_MY_FB_APP&client_secret=SECRET_ID_OF_MY_APP&grant_type=fb_exchange_token&fb_exchange_token=GENERATED_ACCESS_TOKEN_FROM_THE_FIRST_STEP
and in the browser I saw this error message:
{
"error": {
"message": "The access token does not belong to application APP_ID_OF_MY_FB_APP",
"type": "OAuthException",
"code": 1
}
}
Which is weird, because the APP_ID of my Facebook app is correct, I've tried to post on the wall of the Facebook page and it was working.
But when I try to get extended access token, I am getting the error above.
What's wrong with the access?
Thank you
This almost certainly means what the error says, which is that GENERATED_ACCESS_TOKEN_FROM_THE_FIRST_STEP is not actually from the app ID that you're using in the APP_ID_OF_MY_FB_APP parameter
Check the access token you're trying to extend in Facebook's Debug Tooland ensure it was actually generated for your app
Your AppID param is not the same to the AppID in developers.facebook.com

I am testing the facebook graph API comments
https://developers.facebook.com/docs/graph-api/reference/v2.12/object/comments
I checked my permission for the access token it contains the permission, which required by API. see the screenshot
I test my object-id (1797963943566411_1975256375837166) which is correct see me screenshot
Change the request method to POST and adding post data {"message": "haha"}
I get the error message shows:
"(#3) Publishing comments through the API is only available for page access tokens" see my screenshot
As you can see the first step checking, I have all the permission that the
API required.
Can any one see any sort of error in this process?
Try another way still not work.
I have a user who post a photo on his own facebook page.
I logged in with this user and give this user all permissions see the screenshot
enter image description here
call /me/accounts to get page access token
enter image description here
copy the page access token into the Graph API Explorer's access token field
call
GET: 1797963943566411_1975256375837166/likes
is working fine
But call POST: 1797963943566411_1975256375837166/likes
Get error response:
{
"error": {
"message": "(#200) Permissions error",
"type": "OAuthException",
"code": 200,
"fbtrace_id": "GtEaBfyXrUD"
}
}
The reason is Facebook changed the API behaviour. We are no longer to use api to like any POST on our time line. API can only like or comments on facebook page. Sad face !!!!
I created and APP on the Facebook.
Now I am trying to post a comment on the user's timeline using the Graph API but I cannot undestand what I need to do.
I already authorized the Application (I authorized this permissions: 'user_status,publish_stream,user_photos,email').
If I look on my profile -> privacy I can see that the APP can:
This app can: Post on your behalf
This app may post on your behalf, including status updates, photos and more.
Last data access:
Basic InformationToday
See details ยท Learn more
Posts on your behalf:
Who can see posts this app makes for you on your Facebook timeline?
Public
Notifications:
When to notify you?
The app sends you a notification
So this part seems OK.
On my application I do the following to try to post somenthing on my timeline (I need to post it when I am off line).
1) GET : https://graph.facebook.com/oauth/access_token?client_id=APPID&client_secret=*APP_SECRET*&grant_type=client_credentials
RESPONSE:
access_token = 422828347771671|UdQELQIf0N7krF4JUo7VwtPLTkk
2) GET: https://graph.facebook.com/search?q=myemail&type=user
RESPONSE:
_"error":_{
______"message":_"A_user_access_token_is_required_to_request_this_resource_",
______"type":_"OAuthException",
______"code":_102
___}
But reading the documentation (https://developers.facebook.com/docs/reference/api/#searching) it seems that this request does not need any kind of access token.
I also tried to add the access token, but the result is still the same.
3) I know my facebookid so I tried to use it directly:
POST: https://graph.facebook.com/100001139132403/feed
ARGUMENT:
access_token=422828347771671|UdQELQIf0N7krF4JUo7VwtPLTkk,
message=Hello
RESPONSE:
"error": {
"message": "(#200) This API call requires a valid app_id.",
"type": "OAuthException",
"code": 200
}
}
So I tried to add client_id=APPID and app_id=APPID, I tried to put one, the other and also both arguments as GET or POST but nothing changed.
I checked the APPId ad it is correct.
Do someone have any idea?
Thank you!
You cant simply generate a user access_token by querying to a URL. What you did gives the App access token and as the error say, you are trying to do something, that needs user access_token.
Refer and implement this : https://developers.facebook.com/docs/howtos/login/server-side-login/
And use that access_token for the rest of the processes.
I'm getting the following error when I try to access the Graph API with my access token:
{
"error": {
"message": "Expected 1 '.' in the input between the postcard and the payload",
"type": "OAuthException",
"code": 1
}
}
I'm grabbing the access token after successfully authenticating an app I'm working on. I have accepted the permissions and I'm hitting the app's landing page. The access token doesn't look like others I've seen online. It doesn't have the '|' character in it. It does have a period and some underscores along with the typical alphanumeric combination.
I figured out the problem. The other developer I was working with used part of the raw signed_request object (not parsed) to form the access token. After taken a gander at the documentation, I quickly realized that you need to parse the signed_request object first before obtaining the oauth_token value. After that was fixed, I was able to easily make an API call.
Check to ensure you are verifying the "code" parameter returned by Facebook before signing the request, not the "access token". Signing a request with a bad access token produced this error message for me.
Is it possible to retrieve Facebook page statuses using an app access token?
According to the documentation I could use "any valid access_token or user access_token" but when I try to use the application access token I'm getting the following message: "A user access token is required to request this resource.". Am I generating the app access token in a wrong way? Is there anyway to access the statuses of a public Facebook fan page without a user?
It seems that a user access_token is required to query this connection.
Tried without any access_token in the Graph API Explorer on redbull page and the result was:
{
"error": {
"message": "An access token is required to request this resource.",
"type": "OAuthException"
}
}
But after providing an app access_token:
{
"error": {
"message": "A user access token is required to request this resource.",
"type": "OAuthException"
}
}
This is a bit misleading!
Don't know if your still facing this issue. But here's a workaround :
By asking the graph API, you have this issue, but by using the FQL langage, it works perfectly with an App ID!
Here's an example for the 'PSG' page :
https://api.facebook.com/method/fql.query?query=SELECT post_id, type, attachment, message FROM stream WHERE source_id IN(SELECT page_id from page where username='PSG')&access_token=YOUR_APP_ACCESS_TOKEN
;)
I did quite a bit of homework before posting here but still could not find a solution for the following problem.
PROBLEM: when trying to access my facebook app's insights or subscriptions, it returns
{
"error": {
"message": "An access token is required to request this resource.",
"type": "OAuthException"
}
}
I do everything according to the official documentation:
get app access_token by calling this api. It does return a token.
https:// graph.facebook.com/oauth/access_token?client_id=APP_ID&client_secret=APP_SECRET&grant_type=client_credentials
get insights/subscriptions by calling: https:// graph.facebook.com/APP_ID/subscriptions?access_token=TOKEN_FROM_STEP_1
but the last call returns the error message above.
Any ideas why?
After many trials and errors I found the solution.
Change facebook app type to 'Web' instead of 'Native'
Apparently facebook doesn't return subscriptions/insights for native apps
