If you go to an address like:
http://example.com/workflow/oauth2/auth ... IOJ&scope=*
(replace with your host name, workspace and client_id)
Then, you will be redirected to the login screen.
After logging in, then you will redirected to an address like:
http://localhost:320/workflow/oauth2/au ... IOJ&scope=*
where you can Accept or Reject the authorization to access your PM account through REST.

If the user clicks on Accept, then the web brower will be redirected to the callback URL that you set in the configuration of your REST application.
That callback URL should be a script to obtain an access token that can be used in subsequent REST requests.

If you didn't set a callback URL in the configuration of your REST application, then you will see this message on your screen:

Code: Select all

{"error":"invalid_uri","error_description":"No redirect URI was supplied or stored"}

There is no automatic redirection to the login screen when the login session expires. Your script needs to check for errors that are returned by the REST endpoints. I forget the exact error message, but after 24 minutes of inactivity you will see it. There is a protocol in REST to get a new access token, but I find it easier to just have your script redirect the web browser to:
http://{host}/{workspace}/oauth2/authorize?response_type=code&client_id={client_ID}&scope=*
and have the user do the login over again.
