Yes, a user can give an app permission to do so via the API.

Is it possible to have a Voice and Video call feature for a Facebook page messenger app that I created in my site?

I am working on implementing Facebook PAGE messenger for my site and I want to add a feature that I can call Facebook User who message my Facebook PAGE. I already search on google about this matter but still no luck. is this possible to do?
If not possible do you have any suggestion how can i call the Facebook User and how can I implement it in my site.
Thank you in advance happy coding
This is not possible using Facebook provided API's.
However you can send the user a Call button with your businesses phone number which they can one-click to call you.

How can I log into Facebook as a user from an iPhone app so I can post to their wall?

I have an app that must send a game score to someone's Facebook wall, but I don't know how to sign them in from the app.
Can you sign into facebook using only url parameters or PHP code? Something like: http://facebook.com?login=**myusername**&password=**thepass** using GET OR POST. If so, how?
No. To post to a user's wall on Facebook, you'll need to have them install an app you write with the publish_stream permission, and then you can use the scores endpoint to publish those scores.
No, Facebook would have never coded this as it is quite the security vulnerability for brute forcing users' passwords.
You should take a look at the Facebook API.

Why does the Facebook auth page say we "post on your behalf" even though we don't request publish_stream?

We have a mobile app (ios and android), and we request the following Facebook permissions when a user logs in to our app using Facebook: "offline_access,user_birthday,user_relationships,email"
The Facebook Log In dialog has recently started to say that "This app may post on your behalf, including status updates, photos, and more." We don't request the publish_stream permission, so does anyone know why this is appearing? It's a rather scary sounding request that we'd rather not have show up.
If it matters, we're building an html5 app inside phonegap, using the facebook phonegap plugin to do log ins via the native Facebook app.
Thanks!
Looks like this is a bug and was reported yesterday and is on dev facebook bugs.
Check this
Hope this helps
Which permissions are you granted after login? That looks like the description for publish_actions, which is pretty similar in operation to publish_stream since some recent changes
Refer to this blog of facebook:
http://developers.facebook.com/blog/post/2012/04/25/streamlining-publish_stream-and-publish_actions-permissions/
I think it's harmless- their way of getting our permission to publish posts how you want them posted- for example, with the photos you are adding.

Logging in other Facebook users from a standalone app

I have a kiosk-like device that I'd like to integrate with Facebook. Essentially, I'd like to allow a user to log into their Facebook account, give permission to my app, which will post a text/picture/video to their wall.
Is this possible?
What API/toolkits do you recommend?
Thanks

Use the Facebook Graph API. Here is the link: https://developers.facebook.com/docs/reference/api/

Share a link on FaceBook without creating a facebook app

From my iPhone app I would like to share a link on Facebook. I know that this can be done by creating an app in the facebook and use the id/key of that Facebook app.
Is there any other way for sharing a link in FB, like the AddThis library for webapps. So that I neednot create an app in the facebook
AddThis has iOS Sdk now : http://www.addthis.com/help/ios-overview
Not that I know of. AFAIK, the best & easiest way to do this is w a Facebook app. User authentication (through a Facebook app) is required in order to post anything to a wall; anonymous wall posts are not allowed. It's really easy to create a Facebook app. Then, check out the facebook-ios-sdk.
Unfortunately you cannot have anonymous wall posts to facebook, so I would recommend using the sdk, if you only need to post to walls, take a look at www.getsharekit.com which will make this trivial to do
