I am trying to handle the OAuth 2.0 3-legged flow with Web Service Client in Scala Play in a MVC architecture project.
So basically in a 3-legged flow initially (by passing client id, client secret and redirect URIs) we receive a grant token with which we can fetch the access token and the refresh token to access the data resources.
The above grant token is received in the redirect URL after successful login to the site.
How to fetch the grant token from the redirect url after successful login? Any form of help is appreciated as in a flowchart, description or code snippet.
