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 currently using Facebook's OpenGraph to obtain taggable_friends. By default and as of FB API > 2.1 the request only returns 25 objects. You can add a limit and increase your data response but you have no parameters you can pass. It just doesn't feel right to increase the limit with a hard coded number. So, one of the features of that app is that you can search for taggable_friends and select them. If you return a large limit to obtain (in most cases) all of your friends can take a while. Let's say you only get the first 25 and you search for a person that is in a batch - you don't know where. Since you have no parameters to pass to your request, a searchTerm for your your API call is out of the question.
Has anyone ever done a batch call? Facebook allows for multiple requests using some sort of batch calls. How would that look like in JS code?
I can use my users information to obtain the amount of friends he/she has and set a reasonable limit. That helps in the majority of cases but doesn't solve the problem.
Did someone ever encounter that problem and solved it?
I'm using Facebook Marketing API to get ad campaingn from Facebook. I'm getting the data, but the problem is, they are sending the data with pagination. I have the url for the next set of data, so I need to call the Facebook API multiple times. I can set the data limit in the request to a huge number so that I can get all the data at a time.
Is there any other option to get all the data?
I tried with until & since parameter and sending the timestamp of current time & 0, but it didn't worked.
So is there any other way out?
Paging through the data is the way to go. There is no alternative.
There are indeed different ways to use paging, one of which would be to use the next/previous links provided in a response. Another way is to use so-called Cursor-Based Pagination, where you construct your own next/previous links using a provided cursor tokens. This is documented here.
Please not that you can indeed change the requested limit to some huge number, but Facebook's API may silently reduce that number to whatever it thinks is sensible, or it may return an error saying that you requested too much data. Summarized, this means you will need to use paging.
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.
https://developers.facebook.com/bugs/1904674066421189/
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.)
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.
