I have one Customer's Salesforce Application and one .Net Web Service. I also have Connected App in Salesforce which I am using to generate new token.
Salesforce Application calls .Net Web Service and pass session id and refresh token. .Net Web Service uses session id for authentication while interacting (using http request) with Salesforce.
I have logic in .Net Web Service to get new access token when current session id get expired using refresh token.
Now, I want to remove dependency of Connected App because of some reasons. So I want to know is there any way to get new access token without using Connected App?
