I am always and constantly getting the following error when trying to follow a user via instagram although the 5000 request limit hasn't been exceeded. Why is this?
{"meta":{"error_type":"APIError","code":400,"error_message":"Client request limit reached"}}
While API request with access token is 5000 (any API call), certain API like follow, unfollow, like, comment are limited to 350 an hour.
I had the same problem. In my case I sent post requets from server side (google app engine) and now I am sending post requests from client (with js) and it works well.
It depends on your request. Instagram has a new API limit, 100 likes/hr, 60 follow/unfollow/hr IF you authenticate server side and sign your headers, check out the Instragram authentication for developers.
I'm currently running a website: http://instapromobiz.com that automates likes/follows/unfollows using these restrictions. It works great, check it out.
