How to check user token limits?

Question

How to check user token limits? and why, when the maximum number of queries, requests continue to send? Maximal limit is 5000 requests.

Answer 1

The API documentations says:

Be nice. If you're sending too many requests too quickly, we'll send back a 503 error code (server unavailable).

So I guess you should look for a 503 as your indication that you've hit the limit. I haven't actually verified that this is the case, but it appears they have an Apigee front end, so I suspect it would work as stated.

Answer 2

The response header for Instagram API has information on API limit and how much has been used.

Look for X-Ratelimit-Remaining and X-Ratelimit-Limit

Cache-Control:private, no-cache, no-store, must-revalidate
Connection:keep-alive
Content-Encoding:gzip
Content-Language:en
Content-Length:10117
Content-Type:application/json; charset=utf-8

Expires:Sat, 01 Jan 2000 00:00:00 GMT
Pragma:no-cache
Server:nginx
Max-Age=31449600; Path=/
Vary:Cookie, Accept-Language, Accept-Encoding
X-Ratelimit-Limit:5000
X-Ratelimit-Remaining:4995

If you exceed the limit then you will get a HTTP 400 response, with a JSON response that has error_message that API limit has exceeded.
