I am a novice in salesforce. I have access to multiple sandbox instances of salesforce. I am trying to do an OAuth2.0 authentication and call some rest api. But when I request for the token, in the response I am not getting the desired instance url. Any idea how to get the desired instance url?
Because that instance url will be the url for further rest api call that I want to perform.
I am using https://test.salesforce.com/services/oauth2/token to get the token.
