Exchange your client id, client secret, API username and API password for a bearer token.
We currently support one OAuth2 grant type: Resource Owner Password Credentials.
Resource Owner Password Credentials
You can exchange your username, email, client_id, and client_secret for an access token directly.
You will not need to host your own server to receive an authorization code in the callback url.
