Multi-brand Zendesk OAuth support

Customers with multi-brand Zendesk accounts can now complete OAuth setup when their AI Agent is associated with a brand-specific subdomain that differs from the primary account subdomain.

What’s new

Previously, OAuth authorization failed for multi-brand Zendesk accounts because brand subdomains are not valid OAuth endpoints. This blocked affected customers from completing the Zendesk OAuth migration.

A new Multi-brand toggle is now available in the Zendesk connection modal under Config > Apps > Zendesk. When enabled, you can specify both the brand subdomain and the primary account subdomain. OAuth authorizes through the account subdomain, and the connection is stored under the brand subdomain so that Handoff integrations find the correct credentials.
