Question

I can send requests to friends using “Multi Friend Request Selector” inside my Page Tab App, which link looks like :

https://www.facebook.com/<my_page_name>/app_<my_app_id>

My friend receives my request, and click “Accept”. It forwards to the real link of the Facebook App, which is :

https://apps.facebook.com/<my_app_name>/?fb_source=request&request_ids=<an_request_id>

which is not inside a Page Tab anymore. How can I forward to user to the 1st link instead of the 2nd while the request_ids have to be kept? Do I just make a header('Location: url'); forwarding?

p.s. Timeline is already in use.

Answer 1

Yes you have to forward to your page url, because requests always redirect to the canvas url.

To pass the request ids you can use the app_data field. So instead of redirecting to https://www.facebook.com/<my_page_name>/app_<my_app_id> you redirect to https://www.facebook.com/<my_page_name>/app_<my_app_id>?app_data=requestids. Here requestids are the actual values(the comma separated list that the canvas gets).

app_data is available to your page tab app as part of the signed_request it receives.

From docs:

In addition, your app will also receive a string parameter called app_data as part of signed_request if an app_data parameter was set in the original query string in the URL your tab is loaded on. For the Shop Now link above, that could look like this: “https://www.facebook.com/YourPage?v=app_1234567890&app_data=any_string_here”. You can use that to customize the content you render if you control the generation of the link.
