Got a "refresh token is invalid or expired" error even though the User token is brand new
I obtained a new User Token from the sandbox web portal. When I tried to refresh it using the Rest API following the documentation. I got a "refresh token is invalid or expired" even though the User token is brand now. See attached screen shots. Can you check what's the issue?
When you obtain an OAUTH token via the API you get two values in the response. One is the auth token that is valid for a short period of time. The second value is the refresh token that has a longer life span and is the value that you use when refreshing a user token. Sadly when getting an OAUTH token via the sandbox web portal you are only given the auth token which can not be passed when refreshing a user token. eBay will need to improve the web portal so that the refresh token is returned as well.
