Zendesk is introducing an update to its API that requires the use of an OAuth refresh token grant type to manage access token expirations. This grant type refreshes access tokens that have expired or are about to expire. This change is crucial to ensure the security and continuity of customer integrations.

This is an important notice as Zendesk requires third-party app developers to adopt this flow by January 31, 2026, and it will be required for all customers by April 30, 2026. 

Note: Confirm updates on the Zendesk article as dates may shift.

Customers must have at least one connector card running at least once a month to prevent refresh token expiration. If the customer does not send API requests during a month, their refresh token will expire, and they will not be able to get a new access token, which leads to a broken connection.

To re-authorize, simply follow the prompts within the Workflows connector interface.
