Renewing Refresh Token for a Service App

[Urs Wuest]

Hi,
I have the following question:
What do I have to do if the Refresh Token is expired, because I don't used the Service App the last 100 days?
Is there a REST call to renew the Refresh Token if it its expired for a Service App?

Or can I only renew Refresh Token in this case in the Service App Configuration in https://developer.webex.com/my-apps
Or do I have to ensure that I have frequently request an Access Token to renew the Request Token?
What is the recommended course of action in this case?

@Urs Wuest same as for an OAuth Integration (https://developer.webex.com/create/docs/integrations) , once the refresh token expires, you will have to go through the OAuth flow again from the beginning. If you still have a valid refresh token, you can use it to generate a fresh access token, same way as you would do for an OAuth Integration https://developer.webex.com/create/docs/integrations#using-the-refresh-token . 

Note, that every time you use the refresh token, it's validity gets reset back to 90 days. There is a 1-5 days delay with this mechanism, but it will refresh.
