Stuck on Zendesk Ticket-to-Interaction Sync via API

NICE CXone API & Integrations

Stuck on a persistent 400 Bad Request when attempting to map Zendesk ticket fields to Genesys Cloud interactions via the Zendesk integration API. The payload seems valid according to the Swagger docs, but Genesys Cloud is rejecting the request with a ValidationError: Interaction type mismatch.

In Zendesk, we were used to firing off bulk updates without worrying about strict interaction type definitions. The migration guide suggests mapping comment events to webchat interactions, but the API keeps throwing this error regardless of the interactionType value sent. I am trying to replicate the old Zendesk workflow where tickets automatically created a digital engagement. Is there a specific configuration in the Zendesk integration settings that needs to be enabled before the API accepts these mappings?

Environment details:

  • Genesys Cloud Version: 2024-01
  • Zendesk Plan: Enterprise
  • Integration Status: Active
  • Error Log: 400 Bad Request - Invalid interaction type for channel mapping

The quickest way to solve this is ensuring the interactionType explicitly matches the Zendesk ticket category.

  • Set interactionType to voice for inbound calls or email for tickets.
  • Verify the direction field aligns with the interaction type (inbound vs outbound).

TL;DR: Verify payload schema via CLI.

Have you tried validating the JSON against the OpenAPI spec locally? The 400 error often stems from missing optional fields that Genesys requires for specific interaction types. Use genesyscloud interaction create with --dry-run to catch schema violations before hitting the API.

How I usually solve this is by ensuring the payload structure aligns with the specific integration endpoint requirements rather than generic interaction schemas. The unified communications integration endpoints expect a specific mapping object that differs slightly from standard interaction creation.

Try adjusting the request body to explicitly define the ticketId and map the subject to the summary field. The interactionType must correspond to the channel configured in your Zendesk integration settings within Genesys Cloud. If your integration is set up for voice, but you are sending an email-style payload, the validation fails.

{
 "ticketId": "12345",
 "subject": "Customer inquiry",
 "description": "Details here",
 "status": "open"
}

Verify the integration configuration in Admin > Integrations to confirm the expected interaction type. Mismatches here often trigger the 400 error.

Note: Ensure your OAuth token has the integration:zendesk:write scope. Missing scopes can sometimes mask as validation errors in the API response.
