Facebook api 4 Application request limit reached

Question

Since late November we are hitting the application limit on the Facebook API  We are fetching user s photos  and selected 25 friends photos   this is done when a user signatures in  we are building albums for the users    The above action is limited  but it was not limited till end of November  We are using batch calls to get photos from albums -  is there a better way to get this info without being limited   BTW  according to Facebook we are doing 1M calls per day  but according to our count we are doing 180K calls per day   Fetching only the user s photos without his friend s photos is not a solution for us

The Facebook  Graph API Rate Limiting  docs says that an error with code  4 is an app level rate limit  which is different than user level rate limits  Although it doesn t give any exact numbers  it describes their app level rate-limit as      This rate limiting is applied globally at the app level  Ads api calls are excluded          Rate limiting happens real time on sliding window for past one hour    Stats is collected for number of calls and queries made  cpu time spent  memory used for each app    There is a limit for each resource multiplied by monthly active users of a given app    When the app uses more than its allowed resources the error is thrown    Error  Code  4  Message  Application request limit reached      The docs also give recommendations for avoiding the rate limits  For app level limits  they are      Recommendations          Verify the error code  4  to confirm the throttling type    Do not make burst of calls  spread out the calls throughout the day    Do smart fetching of data  important data  non duplicated data  etc        Real-time insights  make sure API calls are structured in a way that you can read insights for as many as Page posts as possible  with minimum number of requests    Don t fetch users feed twice  in the case that two App users have a specific friend in common    Don t fetch all user s friends feed in a row if the number of friends is more than 250  Separate the fetches over different days  As an option  fetch first the app user s news feed  me home  in order to detect which friends are more important to the App user  Then  fetch those friends feeds first       Consider to limit filter the requests by using the following parameters   since    until    limit    For page related calls use realtime updates to subscribe to changes in data    Field expansion allows ton  join  multiple graph queries into a single call    Etags to check if the data querying has changed since the last check    For page management developers who does not have massive user base  have the admins of the page to accept the app to increase the number of users       Finally  the docs give the following informational tips         Batching calls will not reduce the number of api calls    Making parallel calls will not reduce the number of api calls

The Facebook API limit isn t really documented  but apparently it s something like  600 calls per 600 seconds  per token  amp  per IP  As the site is restricted  quoting the relevant part   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  amp  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   As you can access the Graph API on the client side via the Javascript SDK  I think if you travel your request for photos from the client  you won t hit any application limit as it s the user  each one with unique id  who s fetching data  not your application server  unique ID   This may mean a huge refactor if everything you do go through a server  But it seems like the best solution if you have so many request  as it ll give a breath to your server   Else  you can try batch request  but I guess you re already going this way if you have big traffic   If nothing of this works  according to the Facebook Platform Policy you should contact them   If you exceed  or plan to exceed  any of the following thresholds please contact us as you may be subject to additional terms    gt 5M MAU  or   gt 100M API calls per day  or   gt 50M impressions per day
