How to reauthorize
Go to My account | Service Integrations and reauthorize the relevant integration.
The Reauthorize button is only visible to the app's owner. If you cannot see it, check the Owner field on the app's Information tab.
Revoke vs. Reauthorize
These are two different actions — use them carefully:
Reauthorize – Renews the access token and restores the connection. Use this for routine token renewal or when content has stopped updating.
Revoke – Permanently removes the authorization and deletes all apps linked to that account. Only use Revoke if you need to completely disconnect all apps from a specific account.
