Release 2026.3.1 adds OAuth 2.0 authentication to the Zendesk Support connection in the Zendesk - NetSuite integration app. Zendesk is updating its authentication standards to improve platform security and reliability, and is moving away from Basic and API token–based authentication to OAuth 2.0 with refresh token support.
What's enhanced
Upgrade your Zendesk connection to OAuth 2.0
The Zendesk - NetSuite integration app now supports OAuth 2.0 authentication, in line with Zendesk's authentication guidelines. This keeps automation between NetSuite and Zendesk running without interruption, and keeps your integration secure, stable, and compliant with Zendesk's authentication requirements.
What's changing
- A new OAuth 2.0 authentication option is available in the Zendesk connection settings.
- Basic authentication is removed. Token-based and Custom authentication are being phased out to further improve security and compliance.
Key dates
April 30, 2026: All Zendesk connections must be migrated to OAuth 2.0. After this date, Zendesk no longer supports legacy authentication methods, and they may cause integration failures.
