Is it possible to ask for the wanted permissions and displaying some individual text in the permissions-dialogue that's showed to the user? E.g. "We use the permission to read your mail address to create a new account in our community."?
Thanks,

Earlier the Login Dialog would have the option to display the app description that developers could use to inform the Users about the need for the specific permissions. Which looked like following and was described in this blog post
But the Login Dialog has then seen few modifications, as outlined by this blog post for grater clarity and control due to which the Login Dialog has changed to its current form which has no option for the developers to inform Users about the request. If you want to inform about it, do it prior to sending the User to authorization, as the new Login Dialog looks like
No, these messages are default by the facebook.

I've got a Facebook login implementation (for a website, using the javascript API) for which I want the "email" permission to be required. When the user first logs in, they may deny this permission - which is easy enough to detect by a subsequent look at the /me/permissions endpoint. If I do find they've denied it, I don't continue with the login. So far so good.
Then during subsequent logins, to make sure they get re-prompted for that permission, I include auth_type="rerequest" in my login buttons (which may be rendered via either xfbml or a link with onclick=FB.login(...)).
While this appears to be working, my question is: if I always want the permission to be required, is there any disadvantage to ALWAYS including auth_type="rerequest" in my login buttons? I don't see anything to the contrary in the documentation, and it appears not to have any adverse affect on new users or users who've not denied the permission (i.e. it only changes the login flow - by re-prompting if the user has already rejected something. Which is the behavior I want).
Good practice seems to dictate that I should only include this when I actually know there's something I want to re-prompt, but for the sake of this question, I'd like to know if there are any pitfalls to just always including it.
There is no real downside afaik, but the recommend way is NOT to force users to use permissions they deselected. Instead, show them an input field if they did not authorize the email permission, where they can enter any email they want. Keep in mind that the email field isn't always filled, even if the user accepted the permission.
Are you using Facebook login button? It works for me to re-asking for a declined permission.
Just adding auth_type="rerequest" in the button.
<fb:login-button scope="email,user_birthday,public_profile" auth_type="rerequest" onlogin="checkLoginState();"></fb:login-button>
Hope that can help you.
I have a facebook application and want to use it to allow my users to post simple messages on a page.
I used api explorer and made a few api calls to post but all that I post is not visible for other users than the one I am logged with and for not-logged-in users. I want my api-made posts to be visible for everyone, not just for the user that posted them.
I mention that if I make a post using the textbox directly (manually) on the page then those posts are visible to everyone, even for non-logged-in.
Is there a step-by-step tutorial for this?
What I finally want is to allow users of my site to post messages to facebook directly (after login to facebook of course). Posts should be done by different users to different pages as the respective page.
Code samples are much appreciated.
For posting to a page as the page, get a page access token: https://developers.facebook.com/docs/facebook-login/access-tokens/
To post as the page, you need an access token with manage_pages permission. And there’s no build-in way for a page admin to get notified when someone wants to post to their page as the page, because that’s not a common use case. But the page admin can grant you manage_pages once so you get a page access token, and then you can use that in your app to post to the page, you just have to set that access token explicitly when doing so.
I'm trying to piece together information and different chunks of code scattered throughout the documentation on how to make this happen, since there aren't good examples.
I know I have to first get the create_event extended permission which I get with this code:
FB.login(function(response) {
// handle the response
}, {scope: 'create_event'})
;
I know that I also have to issue a HTTP POST request to 'PROFILE_ID/events' with the create_event permissions and the necessary parameters.
My problems are: 1. I don't know how to collect the create_event permission once it is given. If I run the code above, a dialog box will open asking for the permission but once I accept, only a blank page follows.
2. If everything works the way it supposed to with the permissions request and the post request, will my app see a create event page like I would if I were to create an event on my own from my profile? What interface gets seen from the app? Can I take a user from my app directly to the facebook create event page?

That’s how it works. Everything you want to show to the user after successful login, you have to implement yourself.

No “interface” at all – it’s up to you to build that.
Can I take a user from my app directly to the facebook create event page?
The user can go their by themselves. Why would the need your app for that?
OK, I need some help understanding the process behind Facebook's website integration process and how I can integrate it into my web app....
In its most basic form, my site stores and displays users' comments about products (there's more to it than that, but that's all that's relevant for this question). What I'd like to do is allow them to post that comment, together with the name of the product (and my site), to their Facebook wall by clicking a button.
I do not need the users to log in to my site at all, either with Facebook or any other authentication system and the Post to Facebook part is optional.
Obviously if they decide they do want to post their comment to Facebook, then they'll need to login, but I'd rather temporarily take them away from the page to login, post and then be brought back to my site.
What I need to know is how much of Facebook's APIs, Open Graph and Auth systems do I actually need to integrate?
I had hoped that I might be able to generate a simple link to Facebook with their comment embedded as a POST element...?
I'd be really grateful if someone could point me in the right direction!!
(P.S. I need a similar solution for Twitter, but I think that's easier!?!)
The Feed Dialog doesn’t allow including of a pre-set message any more, so you’d have to make that post via the Graph API if you want to pre-fill the message (and even then, you should only do so, if you’ve given the user the possibility to edit the pre-filled message first).
See here for how to make a post on a user’s behalf via Graph API, https://developers.facebook.com/docs/reference/api/user/#posts
You can do that all client-side, if you embed the JavaScript SDK into your page.
You need to set up an app on FB, then have the user connect to it (using FB.login), ask for the necessary permission (publish_stream) while doing so, and after successful login use FB.api to make the Graph API call.
OK, apologies for the verbose title. Let me give the background in a bit more detail.
My website allows my registered users to create new pages, each of which has its own unique URL. Each page has a Facebook "Like" button on it. I've already implemented Facebook Open Graph API meta tags so that the pages are proper open graph objects, and when some other visiting Facebook user "likes" the registered user's page, a post appears on that Facebook user's wall saying they have liked the page. The Facebook Like widget also displays the number of "likes" that page has received as normal. So far, so good.
What I want to do is allow my registered users to be able to communicate back to the Facebook users who have liked their page. The community of "likers" for a page is a potentially valuable social media resource to the registered user, if only they could communicate back.
I am aware of the "admin page" link you get beside the Like button, which can be used to post to these people, but that is not an option for my registered users as they have no privileges in relation to the Like button.
What I want to do, if possible, is setup a form to capture the registered user's message back to the Facebook users, and then my website sends the message on their behalf, without having to ask for any extra privileges from the Facebook users.
The following Facebook documentation pages seem to say this is possible, but having followed the Open Graph API documentation, I can't get it to work as described - http://developers.facebook.com/blog/post/465/ and http://developers.facebook.com/docs/reference/api/ ("Publishing" subsection). I can get the access token correctly in the first request, and plug that into the second request to do the post, but that doesn't seem to do anything and doesn't return any error.
Since it doesn't work for me, I'm wondering if this is possible as described, or do I need to get some sort of extra permission to do this? I've seen reference to offline_access permission but as I'm new to this stuff I am not sure how it would fit in. If I have to get the Facebook users to grant permissions, this is not going to work as envisaged.
Any thoughts would be most helpful.
The short answer: No, You will never been able to post on someones wall as another user.
The long answer:
You could try to ask for offline access but then you are asking the user to hand over all their facebook data and give you access todo whatever you like their accound, so that is not likely to happend.
The next problem is that they have to be friends to be able to post on each others walls.
Thats why Pages was implemented, so that organisations could announce/talk with the people interested.
However if you have created the like button correctly and give the pages correct meta data, you are able to post to user who have liked it.
Scroll down to Publishing:
http://developers.facebook.com/docs/opengraph/
Just add a form for your user and let your system publish to the correct page, you probably will need a offline token from your own account or similar to use on the server.
Another more complex way could be to generate a facebook page for each page you have on your server.
When the user creates a page on your system a page is created on facebook but as your app as admin.
And when another user likes the page they like the facebook page, hence you have the possibility to post in that page and speak to the user who liked it. (whooa thats a mouthfull).
