As of last night, facebook seems to be automatically popping up a captcha for any stream post from my application. This is for stream posts to my own wall as well as my friends wall. All of the stream posts link back to http://apps.facebook.com/fortyhumans with some addition params for analytics tracking. So I do not believe I am violating the requirement that links must point to the app canvas or website url.
I'm using the following code to do the post.
FB.ui(
{
method: 'stream.publish',
message: '',
attachment: {
name: sName,
caption: sCaption,
description: (sDescription),
href: sHrefLink,
media: [{'type':'image', 'src':sImgSrc, 'href':sHrefLink}]
},
action_links: [
{ text: sHrefTitle, href: sHrefLink }
],
user_prompt_message: sUserPrompt
},
Is there any way to avoid this captcha from popping up? Should I be posting using a different api? The user experience with captchas is very poor. Even posting to my own wall pops up a captcha.
I've read in previous posts here that some people changed to using a bit.ly url or something similar. But that would seem to violate the requirement that links in stream posts must point to canvas or website url.
Any help would be appreciated, or if this is not the right place then where should a question like this be posted.

I created an Application in facebook and used in my website.
In my page I am using this function to share a photo.
function postToFacebook(url, img) {
FB.ui({
method: 'feed',
link: url,
picture: img,
name: "Sample name",
description: 'sample desc'
}, function (response) {
console.log(response);
});
}
This function is working and sending a ShareLink on my Time line. But nobody can see my post. I just can see the post on my TimeLine !!!
What it is the problem?
I found out the problem myself.
it is because of the Status of Facebook Application.
Do this setting to fix the problem:
Go to Facebook Developer => You Application => Status & Review => set this option to YES:
"Do you want to make this app and all its live features available to the general public?"
I want to post to user time-line with their current activity with photo uploaded by them.
For example:
I voted 'xyz movie'.
..image1.. ..image2.. ..image3..
Question : Mutiple photos possible? If yes, Is there limit of photos.I need to show 3-5 photos
Similar to Candy crush saga game post:
(just for reference,not exactly like this. For curiosity I wanted to know whether this is two posts?)
Which api can we use for this?
Is this possible with FB.ui feed api?
FB.ui(
{
method: 'feed',
to:'the Facebook ID of the person you wanna send',
name: 'Facebook Dialogs',
link: 'http://emplido.com',
picture: 'http://fbrell.com/f8.jpg',
caption: 'Reference Documentation',
description: 'Dialogs provide a simple, consistent interface for applications to interface with users.'
},
function(response) {
if (response && response.post_id) {
alert('Post was published.');
} else {
alert('Post was not published.');
}
}
);
What you want is called rich stories, you can create them with open graph, here you can see what are the options available.
This is no easy deal, since you have a lot of options, so you really need to read the open graph docs to find which action fits best. In the docs you have a complete "how to", including how to post an action on a users wall with graph api https://developers.facebook.com/docs/opengraph/using-actions/
Remember that you have to two types of actions, common (docs here) and custom (docs here)
I know that documentation isn't the best answer or the one you wanted to, but in this case it's really necessary, as I said before, you have too many options, that allows you to create the best user experience for your app.
Quoting the docs here's a little example on how to create a story with open graph
To publish an action, make an HTTP POST to the following Graph API endpoint:
/{user-id}/{action-type}
This call should be signed with a user access token with
publish_actions permission or with an app access token for a user who was previously logged in.
For common actions, the {action-type} is the name of the action, such as og.likes:
/{user-id}/og.likes
For custom actions, it is a composite of the app namespace and the custom action type:
/{user-id}/{namespace}:{action-type-name}
The namespace is unique to your app, and is set in your app's dashboard on the Basic tab.
This example is the simplest one.
I have my site qa.carryon.com (this is our test site). I have configured it for facebook login and send invitations. In facebook I have configured SiteURL as 'http://login.qa.carryon.com/gs/'. 'login.qa.carryon.com' is our CNAME and we are using Gigya as social third party.
Login is working fine and when users see the list of facebook friends, user will click on one of them and the facebook send dialog triggers. The link parameter for send dialog is something like this 'http://qa.carryon.com/loyalty/signup?userid=xghdt6ys&username=xyz'.
For this link am i getting the error code 100 link invalid or there is other issue in configuration. I am doing this for first time and i cant understand whats going on. Please help i am stuck with no clue.
I had this issue as well and I was using dynamic querystring parameters on a common URL. It seems you are doing the same.
I fixed the issue by forcing Facebook to scrape the URL before I attempt to send it via the FB UI Send Dialog. Use the FB API to hit graph.facebook.com with the URL posted in the id parameter and a scrape parameter set to true.
Like so:
FB.api('https://graph.facebook.com/', 'post', {
id: '[URL]',
scrape: true
}, function(response) {
FB.ui({
method: 'send',
name: '[name]',
picture: '[Picture URL]',
link: '[URL]',
description: '[description]'
});
});

Does that help?
If there any way to check in PHP SDK if user can write on specific friend's Wall?
Example:
if ($facebook_can_write_to->'123456789') echo "You can write on this friend's Wall";
Using the FQL table (http://developers.facebook.com/docs/reference/fql/user/) you can check to see if the current user can post to a friends wall by loading up the friend's user information specifically the can_post field.
can_post bool Whether or not the viewer can post to the user's Wall.
According to the documentation you can post on a user friends wall if that user granted you the *publish_stream* permission:
publish_stream
Enables your app to post content, comments, and likes to a user's
stream and to the streams of the user's friends.
There are some cases in which you won't be able to do so, for example if some user blocked your application then I guess it will fail if you try, so you should just check the response you get back from facebook for the api request and see if it worked or not.
Edit
As far as I'm aware you can not ask the api (nor via fql) "can my application post to this users wall", you can only ask "have this user granted my application the publish_stream permission".
If I understand what you want, I might have kind of a solution for you though.
I say show the user the option to post on a friends wall.
When the user chooses this option try to post on the friends wall (and I assume you are using ajax for that call), if it fails return some kind of code, then in the client side check for that code, if it returns use the javascript sdk to open a dialog.
You have two choices for dialogs, you can use the Feed Dialog like this:
var obj = {
method: 'feed',
to: "FRIEND_ID",
name: 'A message',
caption: 'Just trying something',
description: 'This is how to post on a friends wall'
};
FB.ui(obj, function(response) { console.log(response); });
Or you can use the Send Dialog:
FB.ui({
method: 'send',
to: "FRIEND_ID",
name: 'A message',
link: 'LINK_URL',
});
With this one though you have to post a link, I'm not sure if that works for you. After you tried and failed for a user you can save that data and use it later.
I don't use Facebook, so at a bit of a loss here, as the API documentation doesn't quite answer this, perhaps someone here knows...
Looking at building a Facebook app to assist publishing from a content-driven web app. Obviously we need authorisation via OAuth to publish an app link to a facebook user's wall, but is authorization for everyone viewing the app within Facebook required? We have no interest in making use of the viewer's facebook data, we just want to show them a page.
If they have to authorise the app, then that's a bit of a barrier - but it's not clear if they can just view the app without anything getting in the way.
"is authorization for everyone viewing the app within Facebook required?"
If you mean having your app post a link to their wall, then yes, you will need to ask for their permission to do so. If you mean can other friends can see the post made by your app to an authorized user's feed? No the friends do not need to authorize your app to do that.
But remember Facebook now has the ability for you to specify which groups can see the post. See https://developers.facebook.com/docs/reference/api/user/#posts and read about the privacy field.
Yes, you can show app without any authentication. If you want user to share content then you can do it like this. Code is few months old, so I don't know if that works.
You cannot set custom text/message for the user. This will display popup window where user must confirm sharing/posting to wall.
<div id="fb-root"></div>
<script src='http://connect.facebook.net/en_US/all.js'></script>
<script type="text/javascript">
FB.init({appId: 'APP_ID', status: true, cookie: true});
function share(object) {
var obj = {
method: 'feed',
link: 'http://apps.facebook.com/your_app_url/',
picture: object.picture,
name: object.name,
caption: object.caption,
description: object.description,
action_links: [
{ text: 'My Cool App', href: 'http://apps.facebook.com/your_app_url/' }
]
};
function callback(response) {
}
FB.ui(obj, callback);
}
</script>
If you're doing a canvas app, you don't need to. You get this generic information in the initial HTTP post:
user A JSON array containing the locale string, country string and the age object (containing the min and max numbers of the age range) for the current user.
algorithm A JSON string containing the mechanism used to sign the request.
issued_at A JSON number containing the Unix timestamp when the request was signed.
You get no actual information about the user, though. You need to authenticate to get that.
