From Facebook Developer Wiki

I assume one status may be that of a request having been sent by an application but NOT YET accepted. I do not know if facebook currently stores pending application request status in any of its public tables. This would be a good place to do it.

Facebook should store the APP ID in this table as status_id whenever an application causes an fb:request to be made - and that field should be indexable. In this way, an app can find all outstanding requests already made by the logged in user.

This knowledge is critical for many applications to avoid redundant requests and to credit appropriately.

[edit] pending status?

I think you're confused and both of our posts should be removed by you, Ken, after reading.

status is the user's status, not an application's "status request" (I don't even know what that means). And if an application sets a users status, then the apps ID is indeed saved in the "source" field.
