Facing an issue with Facebook API. Looking out for help to understand the reasons and resolve the same
We are trying get public wall messages containing a particular keyword.We created application with permissions including read_stream and manage_posts. Application visibility is public and most of other settings are defaults. We could see API working and getting the feeds. Last week we observed an issue. Search API is not picking up messages from certain users. We picked up couple of such ids did some testing. Privacy settings all seems to be fine. Posts visibility settings are public both at feed level and account leven. Platform is turned on. Visibility to search engines is on. For these selected IDs we tried to get wall feeds using their IDs. Below are the observations.
1. For a certain ID we could get all messages both in search and wall retrieval. Both with our application key and default Graph API Explorer access key.
2. For one ID we for messages using Graph API Explorer but not with our application. With our application only feeds we see response are friend request accepts and likes to some other public posts.
3. For another ID Graph API explorer is giving empty results and out application key is giving likes etc as observed in above case.
4. For one of the Use we asked him to turn off the Platform, we were getting messages before. When turned off we stopped getting messages. When turned on we didn't get all messages but only likes etc.
5. When we use Social Mention (socialmention.com) and search for keyword, we could see all messages.
We feel it has to do something with the Application and access key permissions but couldn't get much details. Any help in cracking this is welcome.
Update (May 05, 2014):
The issue is with the way access token generated.
While generating access key we can select permissions to match application requirements. Any thing beyond basic permissions require permission from User. For example if we choose user_location permission, user need to provide permission to get that information. If no additional permissions selected, application will not require any permission and can access all the public data. But if any additional permissions are selected and user not given permission, we cannot get even the public data of that user. With default permissions I generated access key and could get all public data as expected.
