Hi,
I am trying to use a three-legged authorization flow to authenticate a user in my application. However, I am having an issue in the first step, requesting an authorization code:
I try to make a POST request to https://platform.devtest.ringcentral.com/restapi/oauth/authorize with response_type: code, client_id: APP_KEY, and redirect_uri: URL and I get a 405, method not supported.
What am I doing wrong?
