MC1492163 - Microsoft API Hub: Zendesk OAuth tokens will require expiration and automatic refresh

Microsoft 365 Message Center announcement MC1492163.

MS Message Center's Summary

Microsoft API Hub is updating Zendesk OAuth tokens to expire after 48 hours and refresh tokens after 90 days, with rollout starting in early October 2026 and finishing by late January 2027. Existing connections will not migrate automatically and must be reauthorized before early 2027 to prevent flow failures. Administrators should audit current Zendesk connections, brief development teams, and ensure all legacy connections are reauthorized well before the deadline.

Administrator impact
Administrators must identify and reauthorize existing Zendesk connections before early 2027 to prevent operational disruptions.
End user impact
Users may experience connection failures in workflows relying on Zendesk until those connections are manually reauthorized by an administrator or owner.
Importance
6/10: Requires proactive reauthorization of existing connections before the deadline to prevent service failures in dependent workflows.

[What and why] 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 [Impact on your organization] Who is affected Organizations using Zendesk OAuth connections in Microsoft API Hub Developers who manage Zendesk connections and affected flows Platforms and services Microsoft API Hub Zendesk integrations and connected workflows What will happen New Zendesk connections will receive access tokens with a 48-hour lifetime, refresh tokens with a 90-day lifetime, and automatic token refresh support. Existing Zendesk connections created before this change cannot be automatically migrated to the new token model. Existing connections must be reauthorized to receive expiring tokens and automatic refresh support. Active new or reauthorized connections should refresh automatically. Connections that remain unused for 90 days may lose refresh capability and require reauthorization when they are used again. Flows that rely on existing Zendesk connections may fail until those connections are reauthorized. [Action required and recommendations] Action is required for existing Zendesk connections created before this change. Identify existing Zendesk connections that require reauthorization. Reauthorize those connections to receive expiring tokens and automatic refresh support. Inform developers who manage Zendesk connections and affected workflows about this change. Review affected flows that depend on existing Zendesk connections. Learn more Zendesk - Connectors | Microsoft Learn [Compliance considerations] No compliance considerations identified.
