The default access token expiry is 24 hours, and currently, there is no information on customizing token expiry. Coupa generates an access token which lasts for 24 hours, so Coupa’s recommendation is to renew the token every 20 hours (like a refresh token). We recommend creating a new token call before the existing token expires. To get a refresh_token, you must enable the offline_access scope in the Oauth app, which must be passed in the authorization request. We do not have clear data on the refresh token expiry. |
