To align with updated Zendesk security requirements, Microsoft API Hub is changing how OAuth tokens are issued and managed for Zendesk connections. New Zendesk connections and existing connections that are reauthorized after rollout will receive access tokens that expire after 48 hours, refresh tokens that expire after 90 days, and automatic token refresh support.
Rollout schedule
General Availability (Worldwide): Beginning in early October 2026 and expected to complete by late January 2027
