I have a problem getting facebook to call my credits callback script. I've setup a company and the callback url. I used the example script for it. But nonetheless I always get this error when I try to access the payment window using the JS sdk.
var obj = {
method: 'pay',
order_info: order_info,
purchase_type: 'item'
// dev_purchase_params: {'oscif': true}
};
FB.ui(obj, getCashCB);
Error:
There Was a Problem Processing Your Payment
Sorry, but we're having trouble processing your payment. You have not been charged for this transaction. Please try again.
error code from console: 1383046
meaning:
1383046 AppInvalidDecodedResponse The application return value was invalid after json_decoding the return value.
No matter if I'm in sandbox mode, set the callback url to something completely different.
The callback script is never called.
I've searched far and long for anybody else with this problem, but found nothing meaningful. There was something about the server accepting curl requests from facebook but I don't know what that means or how to test for it.
Solved! Whilst looking for the cause I noticed that this error can pop up from a lot of things. But this case is rather specific:
Because the facebook app is still in development, we hid it behind a .htaccess file. So when you visit the site, you login, and the app loads etc. BUT this doesn't work for the credits callback file. Since the request then comes from facebook, it would have to login with user:pass. I tried putting that in the callback URL, but that doesn't seem to work.
So I only need to put the callback file somewhere where you can reach it without .htaccess and Tadaaa it works!
Basically this happens when Facebook doesn't understand the response it gets from calling your payment callback URL. Thew most likely reasons are:
The callback URL is wrong
Facebook gets an error response because the server or some app-level firewall won't let it access the URL (Jon's problem)
Facebook gets an error response because the callback script runs into an exception.
The callback script's response is malformed.

im currently working on facebook integration into my mobile AS3 game. I'am downloading friends pictures, which works just fine and is not currently an issue. Problem is, i am trying to detect, if user has silhouette (default) picture or his own (is_silhouette property);
Here goes code:
(response[i].id) is valid user id which i have got from previous api comunication
...
HasDefault(response[i].id);
...
private function HasDefault(uid:int):void{
FacebookMobile.api("/"+uid+"/picture", callbackX);
}
private function callbackX(response:Object,fail:Object):void{
if (response != null){
trace(response.url);
trace(response.is_silhouette);
}else{
trace("here goes nothing...");
}
first things first...this code above has 2 issues. First problem is, unless i use absolute URL, facebook does not respond, so API method has actually look like this:
FacebookMobile.api("https://graph.facebook.com/"+uid+"/picture", callbackX);
i dont know why i have to use absolute url here, because anywhere else id/function is good enough...but that is not still main problem.
If i use absolute URL i do get valid response from facebook but according to this https://developers.facebook.com/docs/reference/api/using-pictures/ i should get response.url and response.is_silhouette in my response object. i however recieve only empty response object...I'am starting to be realy desperate.
In addition, i have tried to paste THE SAME request into the https://developers.facebook.com/tools/explorer explorer and surprise surprise...it returns
{
"data": {
"url": "https://fbcdn-profile-a.akamaihd.net/hprofile-ak-frc1/somenumbers.jpg",
"is_silhouette": false
}
}
...which is exactly what i need...but within the application i get only empty response object...
I do not know what you line "FacebookMobile.api("https://graph.facebook.com/"+uid+"/picture", callbackX);" does.
But whatever library that is, stop using it, because its not letting you specify the call you want to make. You can just call the graph api calls yourself using a URLLoader.
So here is the magical thing that is going wrong: You need to be able to append an extra variable when you request the picture: "?redirect=false"
This tells facebook to give you a json response. If you do not have that variable, you will get a redirect to the actual image, which is usually what a person wants anyway.
To see how that works, test out the two links below, one with redirect=false - which you want. and One with it set to true - which you do not.
https://graph.facebook.com/shaverm/picture?redirect=false
https://graph.facebook.com/shaverm/picture?redirect=true
I am pretty sure what is happening is that you are getting the image back instead of the json response describing the image.
I've create an facebook app and it run smoothly at
https://apps.facebook.com/icoloringstar/
But the problem is: when I search my app name "icoloring star" in facebook, it link to the app at url:
https://apps.facebook.com/icoloringstar/?fb_source=search&ref=ts
Then facebook said that:
App "iColoring Star" is unavailable
The app "iColoring Star" is temporarily unavailable due to an issue with its third-party developer. We are investigating the situation and apologize for any inconvenience.
We found that url part "ref=ts" cause above problem, but really do not know why?
Could you explain me why and how to resolve this problem?
Thank you very much.
It sounds like your code is failing when the ref parameter is supplied in the request path.
I was able to repro this with any arbitrary value in the ref parameter when accessing your app
Check your server logs and and see if you're returning a 500 error to facebook when the request comes in
See if you have any code that parses a ref parameter and check it's not throwing exceptions
Make sure your callback URL in the app settings doesn't also specify a ref parameter or your app may receive two values and/or fail entirely
It means 'Top Search'. User enter a query into the top of search.
There are some ref parameters.. ref=bookmarks for example. I dont know the full list.
Did you put your app on Facebook App Center?
I am at this step in getting my app started in the documentation:
https://developers.facebook.com/docs/appsonfacebook/tutorial/#auth
In there is a code block that (supposedly) forwards the user to a request dialog asking permission to access certain bit of information about them. I've placed this code block into the PHP script that my canvas URL points to, and changed the $app_id and $canvas_page to my application ID and canvas URL respectively. Instead of getting the expected dialog, I receive this following error from facebook:
"An error occurred. Please try again later."
No other details about the error are present. I've tried some variations of the script, and have even tried loading up this URL directly just to see if that would work. Note that I've replaced YOUR_APP_ID and YOUR_CANVAS_PAGE with the appropriate values and made sure that spelling and/or punctuation are correct:
https://www.facebook.com/dialog/oauth?client_id=YOUR_APP_ID&redirect_uri=YOUR_CANVAS_PAGE&scope=email,read_stream
For the redirect URL, I've tried prepending it with http://, https://, and no prefix at all. All with the same result.
My question: is the example in the documentation broken, or is the oauth link provided in the documentation currently down? The vague nature of the error is somewhat frustrating since I can't tell if it's something I'm doing wrong or if it's facebook's oauth function that's at fault.
So, the problem was that instead of using the numeric application ID that facebook assigned for me when I originally created the app as the YOUR_APP_ID parameter in the OAuth URL, I was using the application namespace string. Facebook didn't understand this sort of request, and returned the generic error message.
Once I used the numeric app ID, the OAuth dialog popped up to ask permission to access my account, as expected.
I am adding Facebook login to my existing asp.net application. I have added a Facebook login button to my login screen. Now, I click Facebook's login button and in IE 9 it throws client-side exception in all.js on Line 22: if(a.params)b.fbCallID=a.id;
Even after that exception I see the Facebook login screen and can log in, and in the main browser window I get the auth.login event, so I can live with that.
But, if I am already logged in to Facebook, I come to the page and click Facebook login button, I briefly see the empty popup window, then I get teh same client-side exception, and then I get no event in the main browser window, so I don't know if the user logged in so I can't redirect them to another page.
I tried the channelUrl trick but it didn't help.
Any suggestions what's going on?
I found this hack that fixed the issue for me; add this line right after you call FB.init():
// Hack to fix http://bugs.developers.facebook.net/show_bug.cgi?id=20168 for IE7/8/9
FB.UIServer.setLoadedNode = function (a, b) {
FB.UIServer._loadedNodes[a.id] = b;
};
The reason it is happening (from the websites and documents I have read, and believe me, I've read a LOT) is that IE refuses cross-site javascript, and it sees the all.js as crossing the sandbox border. A good discussion can be found here.
Some people say that adding the channel.html file works, but we have tried all flavors of that, and have not had any success. (Remember that the http or https must match the page sending the request.)
Microsoft makes reference to this same issue and their advice is to add the site to trusted sites (that doesn't help). Old advice (from last year) is to add CP="HONK" as your compact privacy policy, but I think that bug was fixed, and it was cookie-related.
What seems to be happening to us is that the login actually continues, and the callback gets called properly, but the main thread that should complete outside of the login call stops executing (because of the error). So, any functions outside the login fail to execute after the login call.
If anyone has a way to get IE to not throw the exception or to create a workaround for this issue, I am desperate to have it. Any info needed I will be happy to provide, but a sample is here:
enter code here
code before login here...
FB.login(function(response){
callback stuff here... This part fires.
});
main thread stuff here... This fails because of permission denied error.
The title really says it all. Under some (undetermined) conditions FB.getLoginStatus() just stops working and won't invoke the callback I gave it. The only interesting clues I've found are
FB.Auth._loadState is stuck on "loading" -- whatever is supposed to make it click over to "loaded" isn't happening
slight delays like putting in alert() calls tend to make it start working
Any hints at all about even how to investigate this welcome.
This usually happens for me when I am running the page under a different domain from what has been registered in Facebook. Typically this is when I am developing locally.
If you are running locally, you'll have to set up a local web server and then modify your hosts file to point the the registered domain to 127.0.0.1 in order to test on your local machine. Don forget to remove that line from the hosts file when you want to test it on the server.
According to:
https://developers.facebook.com/bugs/240058389381072
You cannot put your application under sandbox mode, or else it won't work. Go into your app settings, advanced, and switch it. This stumped me for a couple hours until I happened upon the bug report.
I had similar problem with FB API. It turned out, that my Facebook App was misconfigured. Please make sure that this is not the case for you. My problem was that my "Site URL" param in FB application was pointing to https, but I was using http protocol for development. Any call against FB api after FB.init was not calling my callback functions. So the first thing to do should be to double check App config.
Now, if some reason you depend on FB api but you wish to have a fallback option in case it;s inoperative - workaround with timer should be ok for you. Just set up a timer and disable it if FB Api gives you proper response. If not - fallback to some custom function which will perform some additional logic.
function callFbApi() {
var timeoutHandler = setTimeout(function() { requestFailed(); }, 1000);
function requestFailed() {
// When this happens, it means that FB API was unresponsive
doSomeFallbackWork();
alert('hey, FB API does not work!');
}
FB.getLoginStatus(function(response) {
clearTimeout(timeoutHandler); // This will clear the timeout in case of proper FB call
doSomeUsualWorkAfterFbReplies();
return false;
}, true);
}
If your application is in sandbox mode, Facebook acts as if your application is invisible to anyone who is not listed as an application developer. If you're not logged in, then it would stand to reason that your app is now invisible.
The callback will only fire if you're initializing with a visible application. Otherwise the following response is returned:
<span>Application Error: There was a problem getting data for the application you requested. The application may not be valid, or there may be a temporary glitch. Please try again later. </span>
For more info please see my comment on this bug ticket:
https://developers.facebook.com/bugs/240058389381072
Maybe you are using the asynchronous call. The same thing happened when I called FB.init with window.fbAsyncInit. All I did was delay the FB.getLoginStatus with a setTimeout function
window.setTimeout(checkLogStatus, 1000);
function checkLogStatus(){
alert("check");
// fetch the status on load
FB.getLoginStatus(handleSessionResponse);
}
It seemed to work after that
On the new version of the Developer app, you have to make sure to have put the correct URL you are using to access the application in the Website field under the
Select how your app integrates with Facebook
section.
Make sure the protocol is HTTPS and not HTTP.
I had a similar problem. The site worked every time when I was opening the browser, but fails when I tried to reload.
The cause was the missing "www" on the site name on Facebook configurations. Note that putting "www" (like www.yoursite.com) works on both situations (yoursite.com or www.yoursite.com).
As others have posted, you must be accessing your site at the same URL that facebook expects. For example if facebook has a callback "example.com" but you're browser has "www.example.com", that can cause this problem.
In addition, if third-party cookies are not allowed by your browser, you may also see this problem. Or you may see the callback erroneously reporting the user is not connected.
Just posting a situation I had were calling FB.getLoginStatus got absolutely no response.
My application is designed to run in a tab, and I only entered the Page Tab URLs on the app admin page, and not the App On Facebook (i.e. Canvas) URLs. The tab loads perfectly, but any calls to the FB JS SDK provoke no response.
In Facebook App Settings, go to Client OAuth Settings, look at Valid OAuth redirect URIs
Make sure you have listed all URIs which are the domains from which Facebook SDK is being invoked. For example:
I develop at localhost:5000 and deploy to Heroku. Notice the format: http://domain.name/
