I'm looking to integrate Jumplead with an external application by capturing new customers upon system registration. I've got an app set correctly with the associated client id and a redirect uri.
However, when I try to authenticate the app via either a GET or a POST request using Oath I always receive a 400 error - "Client authentication failed". The authentication URL structure I am using is: https://account.mooloop.com/oauth/authorize?client_id=CLIENT_ID&redirect_uri=REDIRECT_URI
The CLIENT_ID and REDIRECT_URI are taken directly from my app settings page. Am I missing any additional parameters or is there a certain way I need to approach this?
