I am trying to retrieve the list of members of a group via the Facebook API. It works in principle, but it seems that there's a discrepancy between the number of members as stated on the group page (when accessed via the browser) and the number of members retrieved via the Facebook API.
Steps to reproduce:
Consider for instance the following group: https://www.facebook.com/groups/141499479690556
As of right now, Facebook states that there are 1165 members in that group.
Now, go to the Graph API explorer (https://developers.facebook.com/tools/explorer) and access /v2.10/141499479690556/members?limit=1500 (I set the limit well above the number of group members here to make sure they are all in there).
As of right now, the returned data array only contains 1139 members.
Where are the missing 26 members?
And yes, I am absolutely sure noone "blocked" me or anything. Anyway, I tested this on several groups, even some I have never interacted with. There always appears to be a discrepancy, and the bigger the group, the bigger the discrepancy. In groups with over 5000 members, I have seen discrepancies of 100-200 people.
At first I thought there was a problem with paging (I originally used a smaller limit and used paging), but as you can see, the same problem appears even when the limit is high enough for all members to be returned at once.

If you're seeing a total number of members that's different from the real number, it's possible that some people in the group now have inactive accounts.
When someone's account is inactive, it means that person can't be seen or found on Facebook. Even though he or she is still counted as a group member, they won't appear in the group anymore. An account can become inactive if someone chooses to deactivate it or if the account is disabled by Facebook.

We have a number of groups that come from Azure Active Directory.
Some groups contain more than 200 Users but the total is limited to 200.
Where can I set that all users are visible in the group so more than 200
This is by design a currently only a design limitation.
Azure DevOps UI will only list the first 200 members of an AAD group.
The limitation is only in what members we display, it does not impact the actual permission assignment. If you need to find the related user, you should search on the specific user directly.
I can fully understand your requirement, I suggest that you can create a suggestion ticket in the Developer Community.
I want to scrape emails of the members of a particular group on Facebook but I cannot see them (the group is private) because I am not a member of the group and I would not accepted anytime soon.
This does not seem possible as private groups on Facebook ensure the confidentiality of their members. With Facebook under constant pressure to maintain user privacy I doubt this will become possible any time soon without joining the group.
It appears there was a big update to the facebook api a year ago and a lot of the info online is inaccurate because of it. I'm trying to create a website that provides additional function for members of a specific facebook group; if a user is not part of a specific group I don't want them in it. Some groups may have more than 5k users but if I have to settle for less, so be it. I'm using the php sdk and have successfully made an initial api call with general user information.
Administrators of the group WILL be able to log in, but apparently Facebook isn't approving the "user_groups" permission (?) https://stackoverflow.com/questions/31171082/check-if-user-is-a-member-of-a-specific-group-using-facebooks-javascript-sdk
I found this but I'm not sure how to make it work. Facebook Graph - Possible To Check If A User Is A Member Of A Group w/o user_groups?
I'm using the graph api explorer and I can get a partial list of the groups I'm in but it's nowhere near complete (it displays 4 out of like 20). My thought was that if I can get a full list of members in a group that I could just do an [if user is in userlist then]
What would you do here?
As far as I understand there is no way to do this without some caveat where it won't work (when you have more then 5k members). It also causes you to create a copy of the members list, instead of when a user wants to access the group.
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.

I am running a photo contest on my facebook page via a third party app (shortstack).
The grand prize is supposed to be given to the person with maximum number of Votes.
Each vote is mapped to a facebook ID, which is available to me via shortstack. The problem is that there are too many votes from fake profiles, I inferred this by manually looking at number of friends of the facebook profiles of people who had been voting (I have their facebook Ids).
I am also aware that I can extract out only the publicly shared information of these users via the opengraph.
In short, how should I go about marking all the votes in two categories "Genuine" and "Fake", after subjecting all the IDs to a certain logic that uses information out of the publicly shared user info for that Id?
As an example, let us assume number of friends a particular profile is the only metric that would be used to identify if a profile is fake or not. Now there would be that magical benchmark (number of friends) above which a profile can be considered genuine and below which all the profiles can be considered fake, although there could be some fake people above this benchmark and some genuine fellas below it. In our case, these metrics would also consist of other information a user shares via the opengraph, values and patterns of these parameters being different for genuine and fake users. The point is that I am sure that eliminating fake profiles is very common problem faced by people conducting contests,as they would like to choose the winner on basis of contestant's ability to spread the brand to genuine users. So, there must be people out there who have invested their time inthis, and it would be awesome to get some know-how on this.
