What's the Facebook's Graph API call limit?
Is there any restriction in number of calls we make to facebook's graph api? and If it is there then how many calls can we make per app daily?
Answer
The best answer to this question from another forum, from Ash Rust in 2010:
"After some testing and discussion with the Facebook platform team, there is no official limit I'm aware of or can find in the documentation. However, I've found 600 calls per 600 seconds, per token & per IP to be about where they stop you. I've also seen some application based rate limiting but don't have any numbers.
As a general rule, one call per second should not get rate limited. On the surface this seems very restrictive but remember you can batch certain calls and use the subscription API to get changes."
The above information is now obsolete as of October 2015. It's now 200 API calls per user in any given 60 minute window according to https://developers.facebook.com/docs/graph-api/advanced/rate-limiting
