V3 API: Retrieve the Authorization Code
I'm trying to figure out how to retrieve the Authorization Code programmatically.
On the OAuth2.0 Server Flow -> Step 4 : How do you login programmatically to get the Authorization code?
The URL takes you to a login page where you need to enter your user id and password.
