ServiceNow OAuth - refresh token

[RoliTripa]

When the refresh token expires (e.g. after 1 year lifetime), what would happen? Will it automatically get refreshed and acquire a new one? or will send a sign-in prompt to users asking to enter their credentials manually?

Hi, OOB I don't think anything happens other than authentication failing for the next message\payload, at least that's the result I see in a PDI, after setting access and refresh tokens to expired dates.

I would expect renewal of expired refresh token to be via the third party solution, with the third party having a mechanism to automatically POST a full token renewal request, if they receive any non-authorized type response from any interaction with the target SNC instance.
