Scheduled Change: Zendesk Authentication Migration to OAuth

Category: Maintenance / Security Compliance

Impact: Action required

Components: Shipup × Zendesk Support App, Shipup × Zendesk API Integration

Summary

Zendesk is deprecating legacy private key authentication for third-party integrations.

To remain compliant and secure, both of Shipup’s integrations with Zendesk will transition to OAuth authentication in January.

All existing Zendesk connections must be re-authenticated before January 31, 2026.

Timeline

Phase	Date	Details
Release of OAuth flow	Early January 2026	New authentication method becomes available
Deadline for merchants	January 31, 2026	Last day to re-authenticate integrations
Deactivation	February 1, 2026	Legacy authentication fully disabled

Impact

All merchants using a Zendesk integration are affected:
- Shipup Support App
- Shipup API Integration
Current connections will continue to operate until the deadline.
After February 1, any non-migrated connection will stop functioning, impacting:
- The ability to create Zendesk tickets from Shipup
- The ability to view Shipup tracking information within Zendesk

Required action

No action required yet.

Starting in January:

Support App users: reinstall the app via the Zendesk Marketplace and authorize using OAuth.
API Integration users: re-connect via Shipup Back Office using the “Authenticate with Zendesk” button.

You will only need to complete this once per integration.

Next steps

We will publish:

Step-by-step migration guide
Screenshots / flow details
Reminder notifications before deadline

Another update will be posted here when the new OAuth connection is live.

Notes

We are making this change in compliance with Zendesk security policies.

OAuth improves security and compliance across the integration layer.
