How can I get friendship details in Facebook Graph API?

Question

How can I get a friendship detail for two people? So for example in the web it will be:

http://www.facebook.com/<my_id>?and=<friend_id>

Is there any way I can do this in Graph API? Furthermore can I get specific items such as photos together, wall posts between us, etc? (Not documented AFAIK, but many Graph API features aren't anyway...)

EDIT: I think it should be possible with Graph API. For example getting family details (brother, sister, parents, etc) is not documented yet I still able to do it.

Answer 1

You can simulate a friendship query by doing multiple FQL queries. For example, to get all the photos between two friends A and B, you can:

1. Get all photos (p) from A
2. Get all tags of B in p (query on the photo_tags table)
3. Get all comments made by B on p (query on the comments table)

Repeat, this time selecting photos from B.

You can apply the same concept on other things such as posts, likes, videos etc.
