Problem: I Get A “Callback_uri Didn’t Match” Error

Make sure your callback uri matches exactly, query strings that vary will result in this error. Information that you may want to put in query strings should be url encoded and anything you want passed back needs to be put in the “state” parameter.

Make sure you’re delivering the credentials in the “Authorization” header, not the body.

Request For Enterprise API Access

If you need Enterprise API, put your request here. We will need: company, application, target audience, scale of use (requests per second and expected number of requests per day).
