I've been developing an app with firebase and stripe payment. I've created a checkout session in stripe and added firebase dynamic links for the success_url and cancel_url. The URLs are working fine. I've tested them outside stripe with a simple html file and it opens the app and takes the user to the correct page. If the page doesn't exist it'll take the user to the assigned website. This is stripe checkout session code:
const session = await stripe.checkout.sessions.create({
line_items: [{
price_data: { currency: 'INR', unit_amount: amount, product_data: { name: 'name' } },
quantity: 1,
}],
mode: 'payment',
success_url: 'https://-------.page.link/payment-success',
cancel_url: 'https://-------.page.link/payment-failed',
payment_intent_data: {
application_fee_amount: fee
},
}, {
stripeAccount: req.query.stripeId,
});
I've changed up the actual link since I don't know how much I'm allowed to share. But I can guarantee the dynamic links works fine. But after payment, the test payment at least, it's suppose to open the app and take the user to a payment success page. AND it was working fine for the first 2 or 3 days. After payment it re-opened the app and took the user to the correct page. But when I tried a few days later, this is what it's taking us to:
Again, I've removed the link since I don't know how much I'm allowed to share. It won't even open the app right now. It just shows this message in the browser. Both success and cancel url are doing the same. Why does the links work outside the function but not in it? Has anyone ever faced any similar issues before? Any help will be greatly appreciated.
It seems like you're trying to open the Checkout Session in a WebView which causing the issue in the redirect. Webviews don't know how to handle an URL Scheme other than http:// or https://. That being said, your problem isn't uncommon and there are multiple ways of solving this.
Your first approach would be to open the Checkout Session in an external browser as described in this answer or try to create your own WebViewClient and override shouldOverrideUrlLoading method like described in this answer. Just note that since the last edit of that answer the signature of the shouldOverrideUrlLoading method has changed but the logic should still be used the same way but instead of dealing with the String url, you will have to deal with a WebResourceRequest.
Had the same issue. I solved it by changing the mode like following:
await launchUrl(
url,
mode: LaunchMode.externalApplication, // Add this line
)
url_launcher version => 6.1.7

I'm following this guide, I'm having this code:
var acs = ActionCodeSettings(
url: 'https://example.com/auth/widget',
androidPackageName: 'com.example',
iOSBundleId: 'com.example',
handleCodeInApp: true,
androidInstallApp: true,
androidMinimumVersion: '12',
);
var emailAuth = 'john.doe#pm.me';
FirebaseAuth.instance
.sendSignInLinkToEmail(
email: emailAuth, actionCodeSettings: acs)
.catchError((onError, stackTrace) {})
.then((value) =>
print('Successfully sent email verification'));
Sending the email works, but when I click on the email, then…
in iOS it opens https://example.com/auth/widget - which is the fallback
in Android it shows a circular loader for about 1s and then it "falls down" and nothing happens
The incoming link handler
FirebaseDynamicLinks.instance.onLink.listen((dynamicLinkData) {
print('got dynamic link! $dynamicLinkData');
}).onError((error) {
print('error error!');
});
I configured dynamic links in Firebase to point to to.example.com. I also added a manual dynamic link to.example.com/test which opens my app (the got dynamic link! message shows up) - so all seems fine, the problem seems to lie in the link generation.
The link structure I get by email is:
https://to.example.com/?link=https://example-abcd.firebaseapp.com/__/auth/action?apiKey…%26continueUrl%3Dhttps://example.com/auth/widget%26lang%3Den&apn=com.example&amv=12&ibi=com.example&ifl=https://example-abcd.firebaseapp.com/__/auth/action?apiKey%3D…%26continueUrl%3Dhttps://example.com/auth/widget%26lang%3Den
After some more painful hours of debugging and reading documentation I finally found it out. Most of this is in the flutter documentation, but since the documentation has broken links and is a bit all over the place it was hard for me to catch it all!
Android
I needed to decrease the androidMinimumVersion from 12 to 1. Then my app opens and I can receive the dynamic link. No idea why. My android simulator is android version 13 but the app never opened.
Before decreasing the android version I also set the sha256 setting in firebase, using gradlew signingReport documented in this answer. Not sure though this was required.
iOS
I forgot to do all the steps documented in receiving links on iOS section, namely:
add the dynamic links domain into associated domains
add FirebaseDynamicLinksCustomDomains into Info.plist
Overall, I found that to get this feature working was really really hard for me as a Flutter beginner. But I guess a lot of the setup I can re-use as the dynamic links capability seems to be something which comes in handy in the future.
Prologue:
I have about the same problem as described in the previously asked question (FB add friend dialog on mobile doesnt work).
But since there is no real solution to this problem made known other than the comment:
"it started working ... I didnt change anything." [...] (#dinodsaurus)
I'm asking it again. With some extra information specific to my case.
I'm using the facebook friend dialog by redirecting (302) to an URL like: (https://www.facebook.com/dialog/friends/?id=3500194&app_id=531355753613866&redirect_uri=http%3A%2F%2Fstackoverflow.com%2Fquestions%2F19403197%2Ffacebook-friend-dialog-not-working-on-mobile%23success)
The above URL works fine on both a desktop and a mobile browser.
Facebook automaticly redirects the before mentioned URL to their m.facebook.com domain while using a mobile device/browser. This renders the display=touch version of the dialog (see dialog reference).
This all seems very normal (and is actually wanted behavior).
But... it goes wrong when I confirm that I want to send the friend request. And only when I confirm it using a mobile device.
The message that I get after confirming on my mobile is:
"Sorry, something went wrong.
We're working on getting this fixed as soon as we can."
(Be sure to use your phone's browser for the above link or directly visit m.facebook.com using this link to reproduce the error.)
OK, so I waited two days now since I sent a bugreport (I found out I actually didn't do it the right way but I guess it's already filed before) for this error to Facebook and it seems like there is no fix. Also it seems to me that it's not likely they leave this broken for such a long time. Unless...
Main question:
So my question is actually:
Does anybody know of any reason that Facebook might have for possibly not fixing this error? And if so, is there any way around this while still using a reasonable display style for mobile devices?
Examples of solutions are very welcome... ;)
Edit:
I just filed a Repro for this bug. If you can reproduce the error that I describe here please file a Repro yourself at: https://developers.facebook.com/bugs/309157325894924 so as to give this bug more priority.
As answered by Wimagguc in this question you may try this:-
The underlying problem is that the Facebook API is not yet ready for
all the display types, and the friends dialog cannot be shown for the
mobile display.
protected static String DIALOG_BASE_URL = "https://m.facebook.com/dialog/";
protected static String DIALOG_BASE_URL_FOR_MISSING_SCREENS = "https://www.facebook.com/dialog/";
public void dialog(Context context, String action, Bundle parameters,
final DialogListener listener) {
boolean missingScreen = action.contentEquals("friends") ? true : false;
String endpoint = missingScreen ? DIALOG_BASE_URL_FOR_MISSING_SCREENS : DIALOG_BASE_URL;
endpoint += action;
parameters.putString("display", missingScreen ? "popup" : "touch");
parameters.putString("redirect_uri", REDIRECT_URI);
if (action.equals(LOGIN)) {
parameters.putString("type", "user_agent");
parameters.putString("client_id", mAppId);
} else {
parameters.putString("app_id", mAppId);
}
if (isSessionValid()) {
parameters.putString(TOKEN, getAccessToken());
}
String url = endpoint + "?" + Util.encodeUrl(parameters);
if (context.checkCallingOrSelfPermission(Manifest.permission.INTERNET)
!= PackageManager.PERMISSION_GRANTED) {
Util.showAlert(context, "Error",
"Application requires permission to access the Internet");
} else {
new FbDialog(context, url, listener).show();
}
}
Facebook decided that the bug has no priority and changed the status to "Won't Fix" at December 7th, 2013.
The original bug report was marked as a duplicate of https://developers.facebook.com/x/bugs/309157325894924/. See this page for more info.
I think this is a shame and I would still like to urge anyone who thinks the same to open a new bugreport for the issue. Or leave a comment on the report stated above. Since this seems to be the only way to create some sense of urgency for solving this problem.
PS: I recommend a bugreport since my comments were deleted lately.
PS2: Even my bugreport "to state the won't fix issue in the documentation" seems to be ignored. So every day new people will research the possibilities of a mobile web app with a connection to facebook and will wrongly assume they can use the "facebook friend dialog" in their web app on mobile devices. My hope is that they will find this page during their research, and steer clear off that assumption.
We're moving from the old facebook payments method (which involved FB credits) to the new local currency system. We're using dynamic pricing.
var obj = {
method: 'pay',
action: 'purchaseitem',
product: 'produrl.php',
quantity: 1,
};
FB.ui(obj, FBCcallback);
(Is defining purchaseitem action is "required" or mandatory)
The product url has been scraped and it does give the required results in the debug tool. The callback url is also tested and is working. Yet the error persists. Someone suggested that we leave it over night, that didn't work out either.
Any ideas?
One of the reasons why Facebook would consider the server callback to be not responsive is if the server script caused an error. So if you're using PHP and you get this error, check your error log or use Facebook's sample script for testing.
If the sample works, then there's definitely an error in your PHP script.
I have an HTML5 application that uses Azure mobile services authentication to login (straight from the example code...provided below). It works fine in all desktop browsers and iPhone 5 in Safari. But from app / full screen mode, it does nothing (doesn't ask for permission to show a popup window like it does in safari and no popup windows shows up) and I can wait forever and nothing happens. If I invoke it a second time, it gives an error saying "Error: Unexpected failure"...perhaps because the 1st attempt is still running? Any help/insight is appreciated.
client.login ("facebook").done(function (results) {
alert("You are now logged in as: " + results.userId);
}, function (err) {
alert("Error: " + err);
});
edited update with more info and 2 potential ideas*
I did some more research and found a site that uses an approach that overcomes this problem and also solves two other side effects with the current Azure mobile approach to authentication. I think the Azure mobile team might be looking to do something similar because there are some hints of other authentication options in the code (although difficult to read and be sure because the minimized code is obsfucated). It might be just a matter of activating these in the code...
The "solution":
Go to http://m.bcwars.com/ and click on the Facebook login. You'll see it works perfectly in iPhone Safari in "app mode" becuase instead of doing a popup, it simply stays in the current browser window.
This approach solves two other problems with the current Azure mobile approach. First, the popup gets interpreted by most browsers as a potential ad and is either blocked automatically (desktop Chrome) ... and the user doesn't know why it's not working...or gives a warning which the user has to approve (iPhone Safari in "browser mode") which is a hassle. And if the user has a popup blocker, it gets more difficult and even more potential for the user not getting it to work properly. The bcwars.com method doesn't have this problem.
Second, in iPhone Safari, when the popup window auto closes, the original page doesn't get focus if there are other browser windows open in Safari. Instead, it's in the smaller/slide mode so they can choose which one to show. If this happens, the user has to go through one more sttep...click on the browser window to activate it and give it focus..again more of a pain and more potential for them to mess up and not do it correctly and need help. The m.bcwars.com doesn't have this problem.
Azure options:
Looking at the Azure mobile code it looks like may already have the solution. I can't read it easliy becuase it's minified/obsfucated, but it seems to have 4 options (including iFrame, etc.) for invoking the authentication, and only 1 (the "less ideal one" of a popup) is being used. An easy solution would be to set a property to allow one of the alternate authentications to work. But I can't read it well enough to figure it out. Another would be to hack the code (temporarily until a fix is put up by Microsoft).
Could I get some help there perhaps?
You can implement an authentication flow with Facebook that doesn't use a popup. The basic idea is to use the 'Web Flow' for doing the login, and once the window return from the login, use the access token to login the user in to Azure Mobile Services.
The Facebook documentation for doing this is here:
https://developers.facebook.com/docs/facebook-login/login-flow-for-web-no-jssdk/#step2
Some code samples to make it easier for you.
You would start by something like this:
(Remember to replace YOUR_APP_ID and YOUR_URL with something relevant to your site.
function logIn() {
window.location.replace('https://www.facebook.com/dialog/oauth?client_id=YOUR_APP_ID&redirect_uri=http%3A%2F%2FYOUR_URL&response_type=token')
}
This redirects the window to the Facebook page for the user to log in and authorize your app. When the user is done, Facebook will redirect the user back to YOUR_URL given above.
There you can handle the redirect and do the Mobile Services Login with something like this:
function handleLoginResponse() {
var frag = $.deparam.fragment();
if (frag.hasOwnProperty("access_token")) {
client.login("facebook", { access_token: frag.access_token }).then(function () {
// you're logged in
}, function (error) {
alert(error);
});
}
}
In here you parse the access token you get as a URL fragment and pass it as argument to the login call you make to Azure Mobile Services.
This code depends on the jquery BBQ plugin to handle the URL fragment easily.
Hope this solves your problem!
I have a Facebook app that is built as an iFrame. I am using the JavaScript client API loaded via:
http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php
In my initialization code, I use the requireLogin method to ensure that the user has authorized the app. I have found this to be necessary to be able to gather the user's name, avatar, etc. for the scoreboard. Here's a representative code snippet:
FB_RequireFeatures(["Connect","Api"], function() {
FB.Facebook.init("...API_KEY_HERE...", "xd_receiver.htm");
var api = FB.Facebook.apiClient;
api.requireLogin(function() {
api.users_getInfo(
FB.Connect.get_loggedInUser(),
["name", "pic_square", "profile_url"],
function(users, ex) {
/* use the data here */
});
});
});
This causes the iframe to redirect causing the Facebook authorization screen to load within my app's iFrame. This looks junky and is somewhat confusing to the user, e.g. there are two Facebook bars, etc.
Question 1: is there anything I can do to clean this up while still implementing as an iFrame, and still using the JavaScript APIs?
According to the FB API documentation:
FB.ApiClient.requireLogin
This method is deprecated - use
FB.Connect.requireSession instead.
My experience though when I replace api.requireLogin with FB.Connect.requireSession it never gets invoked. I'd prefer the recommended way of doing it but I struggled and was not able to find a way to get it to work. I tried adding various arguments for the other two parameters as well with seemingly no effect. My expectation is that this method will load in a dialog box inside my app iFrame with a similar authorization message.
Question 2: what am I missing with getting FB.Connect.requireSession to properly prompt the user for authorization?
Finally, at the end of the game, the app prompts the user for the ability to publish their score to their stream via FB.Connect.streamPublish. Which leads me to...
Question 3: am I loading the correct features? Do I need both "Api" and "Connect"? Am I missing any others?
Here is a summary of the changes I needed to make to clean up the authorization process. It appears that iFrames must fully redirect to properly authorize. I tried using the FBConnect authorization but it was a strange experience of popup windows and FBConnect buttons.
Ultimately this game me the expected experience that I've seen with other FB apps:
FB_RequireFeatures(["Connect","Api"], function() {
var apiKey = "...",
canvasUrl = "http://apps.facebook.com/...";
function authRedirect() {
// need to break out of iFrame
window.top.location.href = "http://www.facebook.com/login.php?v=1.0&api_key="+encodeURIComponent(apiKey)+"&next="+encodeURIComponent(canvasUrl)+"&canvas=";
}
FB.Facebook.init(apiKey, "xd_receiver.htm");
FB.ensureInit(function() {
FB.Connect.ifUserConnected(
function() {
var uid = FB.Connect.get_loggedInUser();
if (!uid) {
authRedirect();
return;
}
FB.Facebook.apiClient.users_getInfo(
uid,
["name", "pic_square", "profile_url"],
function(users, ex) {
/* user the data here */
});
},
authRedirect);
});
For iFrames, the solution was ultimately to redirect to the login URL which becomes the authorization URL if they are not already logged in.
I think that FB.requireSession only works from a FB connect site outside of
Facebook. If you're using an app hosted on apps.facebook.com use the php api
call instead,
$facebook = new Facebook($appapikey, $appsecret);
$facebook->require_login();
or link to the login page.
Of these methods to login
* Using the PHP client library
* Directing users to login.php
* Including the requirelogin attribute in a link or form
* Using FBML
only the first 2 are available to iframe apps hosted on apps.facebook.com
I think requirelogin and fbml only work with fbml canvas apps.

Question 1: is there anything I can do
to clean this up while still
implementing as an iFrame, and still
using the JavaScript APIs?
Question 2: what am I missing with
getting FB.Connect.requireSession to
properly prompt the user for
authorization?
Please have a look at this. This article discusses correct use of require session and provides links on how to implement that. And yes, you are right, the requireLogin has been deprecated and won't help any more.
Question 3: am I loading the correct
features? Do I need both "Api" and
"Connect"? Am I missing any others?
As far as I know, you can use both API and Connect together, basically you access Facebook's API with the help of JavaScript.
For iframe apps however, there is no great help and minimum support of API with some handful functionality available. See this for more info.
This causes the iframe to redirect
causing the Facebook authorization
screen to load within my app's iFrame.
This looks junky and is somewhat
confusing to the user, e.g. there are
two Facebook bars, etc.
Finally and personally I have not seen any iframe app requiring user to add the app first. This will create the problem of two bars you mentioned as quoted above.
The link I posted at the beginning of my answer has some useful links to get you started and decide the next-steps or possibly making changes to your apps.
