I have tried raising this concern on Facebook/Support/Bugs but they said I should post implementation issues here. I have read it everywhere and it seems to be quiet open issue till now. I am not sure, If this will be solved or not.
So, what we are doing is, we have clients - Android and iOS.
Apps on Android/iOS allows users to login into the app and generate the token on the basis of permissions set we have, and we are passing this token to server for fetching further data as and when required for client. As our userbase is increasing we are getting Application request limit reached quiet often.
We are fetching photos of users and their friends using FQL. So, when parallely fetching photos for around 8-10 different users, we are reaching the Application request limit sometimes, which is quiet random and we are not aware of the actual scenario when it breaks up and how. According to facebook the limit, which is 1M calls per day, but we are hitting around 80K - 1 Lac API calls in a day, but as users are increasing it is stretching a bit further, Less than or equal to 200 approax calls/user. We tried doing batch calls as well and we hit the application request limit as well.
If anyone of you could help us understand the complete concept of API limit and how this can be handled, then we will really appreciate the help. We want to understand how API limit is decided and it's rate is calculated over which interval so that we will be able to configure on our side accordingly.
Earlier in the day, we ran into a unique API call issue. Our server started to break for API calls for user tokens that are with us, we (on our systems, other than server) tried fetching the data for those tokens (Simple calls - /me or /me/home), and it was working alright for us but not for server, then we tried setting up another server and redirected the requests to our new server then this server works well for the same set of users. Not sure, what went wrong in this case and how it breaks up. Please help.
Many Thanks,
Reno Jones
Did you look at the Insights -> Developer section of developer.facebook.com for your app?
This will show you a breakdown per api call, including warnings and ones that are currently being throttled and why.
Also, are you sure you're using User token authorization and not just your App token?
Beyond that, we take the information from Insights to find api calls to cache on our side rather than hitting Facebook every time. You will likely have to do something similar if you're not already. They have limits for calling too often, as well as for requesting too much data. For those, we had to reduce the limits of historical data we requested.

For my application/crawlers I collect lots of data which leads to exceeding the rate limit very often. I crawl News-Pages and stuff like that so the Token doesn´t need any permissions like posting stuff.
When using the Graph Explorer you can create an User Access Token(lasts 1-2 hours before expiring). You can create as many as you want so I thought it may be possible to abuse this and overcome the rate limit. I tested it and it somehow worked. Did like 6000 API calls with 2 Tokens in under an hour.
Questions:
Did someone else try this already? If so, did Facebook notice and shut down the Account?
Is it possible to request a new User Token from the Graph Explorer via Code or something else like a virtual machine running with an mouse makro to generate new Tokens every ~30mins?
Yes. Yes :) It can go til banning the account or the IP from which the requests are made.
Access Tokens can be obtained by code and you can create more and make some balancing between them combined with different proxies you request through.
HOWEVER I recommend you to use the Facebook ways and respect their politics.
I am using the graph api to get data about pages and the posts in the pages.
When a post is published, it gets liked, commented upon and shared over time. When I read the data next time how can I get the posts that have those changes alone?
the best way is really to set up a server to receive real time updates. Any other way would mean polling facebook endpoints. At a certain point, a single user access token would be rate limited, and would block you from making a call for a certain amount of time. Also, there would be more work to compare each post to the one you stored to see if anything has changed.
Really the most efficient way is to use real time updates in which you set up an endpoint on your server to receive messages from facebook whenever something on a page (or user) has changed. If cost of keeping a server running is your roadblock, I would recommend to setup a free Parse.com account in which you can set up a server to handle Facebook's incoming requests and act on that.
I hope that makes sense! More information on realtime updates here: https://developers.facebook.com/docs/graph-api/real-time-updates/v2.2
So I'm struggling to find where this is documented (if at all), but I'm getting the following error message when requesting data from the FB GraphAPI.
"Please reduce the amount of data you're asking for, then retry your request"
The call I'm making is:
/v2.3/user1/posts?fields=object_id&limit=100
If I change it to:
/v2.3/user2/posts?fields=object_id&limit=100
It returns 100 items.
Why would it work for one user, and not the other?
Both requests are authenticated via an access token (not belonging to either user) and I get the same error whether running it from my code, or the Facebook Graph API console of developers.facebook.com
The response from CBroe is correct. Facebook returns this error if it finds that too many internal resources are needed to respond to your request.
Therefore you have to do what the response says: limit it.
This can be done in (afaik) 2 ways:
Use the limit parameter and reduce the amount of responses you expect from the API
Provide a timeframe (using since and / or until) to fetch only data (posts / videos) for a specific timeframe.
We had the same issue as you, but with retrieving videos from a page. Unfortunately using the limit parameter did not work, even when I set it to limit=1. But by using the since / until parameters we finally got results.
Therefore I suggest to implement a timeframe in order to reduce the amount of data, or alternatively, split the amount of requests you make. e.g. if you want all posts from the past 3 months and run into the mentioned error: split your requests in half using since and until. If that still does not work: keep splitting...
=> Divide and conquer ;)
Hope it helps,

Recent bug filed on FB talks about the same error. They seem to accept that this could be a bug, but not much other information forthcoming.

There are both app-level and user-level rate limits that are enforced on Graph API calls. In your case, it could be that you've made a large number of calls in a short time with user1.
You can check out this page for more about Facebook's rate limits: https://developers.facebook.com/docs/marketing-api/api-rate-limiting (even though the URL refers to the Marketing API, the information also applies to the Graph API.)
When use the Graph API Explorer to visit https://graph.facebook.com/me/home ,sometimes get 4 page data (limit=25), sometimes get 2 page data (limit=25), why it has so big difference , the interval between two visits less than 3 seconds. Anybody knows why?
As per my experience with FB API when it comes to returning result for an API call, FB is bit inconsistent. The problem being faced by you can be attributed to several reasons. One of the reason may be the type of load the FB server is experiencing at that particular time. Note you are not the only user at that point making request to FB Server, There are hundreds of App doing the same at that time. So best option is to use pagination while processing the call back and also try increasing the limit that you are specifying it may not be big help but it will some what improve the results. Hope this helps.
I am getting an FBerror "This operation can't be completed: Application request limit reached".
Does anybody know why is it so? How to check the limit? How to increase the limit? What depends on the limit allocation?
I recently ran across this issue doing a large number of requests using an application access token (the initial project requirements mandated that the user shouldn't have to authorize the app).
After much frustration, we finally were put in touch with a contact at Facebook who provided the following info in response to my question regarding request limits:
There is a limit, but it's pretty high, it should be difficult to hit unless they're using the same access tokens for all calls and not caching results, etc. It's 600 calls per 600 seconds per access token.
Ultimately we ended up requiring the user to authorize, as Facebook does not seem to distinguish between user access tokens (one token per user) and application access tokens (one token for all users) when calculating its seemingly arbitrary request limits.
If you are running into this error with a user access token, you may need to optimize your API calls (possibly by combining FQL queries or replacing multiple Graph requests with a single FQL query).
try this with your php code:
50 continuous FQL calls. After a pause of 10 seconds (sleep (10)) You repeat.
if($nr%50==0)
{
sleep(10);
echo "\n\n---Bloque #".++$numBloque."---\n\n";
}
