    Utilize Salesforce OAuth Refresh Token for Authentication

    Rich Bateman Seasoned Veteran

      Use Case

      Authenticate using OAuth to obtain a valid access token while not storing any credentials (username, password and security token) within ICRT.  The access token obtained will be consumed by a multitude of processes that require authentication back to Salesforce to access Force.com resources. 

       

      Refresh Token

      The refresh token may have an indefinite lifetime, persisting for an admin-configured interval or until explicitly revoked by the end-user. The client application can store the refresh token, using it to periodically obtain fresh access tokens, but should be careful to protect it against unauthorized access, since, like a password, it can be repeatedly used to gain access to the resource server.

      Since refresh tokens may expire or be revoked by the user outside the control of the client application, the client must handle failure to obtain an access token, typically by replaying the protocol from the start.

      The refresh_token can only be Revoked by an Admin of the Salesforce org.  If the refresh_token is revoked the steps (1 thru 3) defined must be manually performed again to retrieve a new refresh_token.
