I know this is not programming but I didn't find any api for developers in facebook. So for that i'm using basic version of facebook. But problem is that i can't go more than three pages of facebook groups members. Ex : https://mbasic.facebook.com/groups/2680624942197490?view=members&refid=18
If I click on "see all" then i can click only 3 times i.e only shows approx 120-130 members but in www.facebook.com verison there is all members.
Is that they desigined it like this? If yes, is there any api to do?
Short Answer : Yes, They have did it like this.
You can use Group - Graph Api For this but it need to be approved.
