I am investigating building an application that will heavily leverage Facebook's app/game groups. During my prototyping I noticed the following limitations:
1) Number of Groups - There seems to be a limit on the number of groups an application may have, that limit seems to be tied to the number of users participating in the application. For example with 1 user participating in the application, I can only create one group. If I add a few more user I can add several more groups. Does anyone know if the specific limitations are documented. I cannot seem to find them and it would be good to know what they are so I can develop my application around these constraints.
2) Number of Groups a User can be invited to - When I try to add a user to more than 5 groups (through consecutive API calls), I get the following error:
OAuthException: (#4002) The attempt to invite the user to the group failed.
Does anyone know if there is a limitation with how many groups a user can be a member of within a given application? Is the limitation based on time, for example can a user join up to 5 groups every hour, etc?? If there is such a limitation are the constraints documented somewhere?
Thanks in advance for the help.
