Data Action failure when mapping Zendesk ticket comments to Genesys Cloud interactions

Is it possible to reliably push historical Zendesk ticket comments into Genesys Cloud interactions using Data Actions without hitting a 400 error?

We are migrating from Zendesk to Genesys Cloud and trying to preserve conversation context. In Zendesk, comments are just text fields attached to a ticket. In Genesys Cloud, we are trying to map these to interaction events. We set up a Data Action to call the /api/v2/interactions endpoint.

The request fails with a 400 Bad Request. The error message says “Invalid interaction type”. We are using the ‘chat’ interaction type, but the payload structure seems different from what the API expects for a standard chat session.

In Zendesk, a comment has a created_at timestamp and an author. We are mapping these to the start_time and participant fields in Genesys Cloud. But the API rejects the payload.

Has anyone successfully mapped Zendesk ticket comments to Genesys Cloud interaction events? What is the correct payload structure for the Data Action request? We want to avoid manual data entry and ensure the migration is seamless for agents used to seeing full ticket history.

Make sure you align the payload structure with the strict schema expectations of the Genesys Cloud Interactions API before initiating the Data Action. The 400 error usually stems from a mismatch between Zendesk’s flexible JSON object and Genesys Cloud’s rigid event definition. When migrating historical data, the system expects specific interaction types and valid timestamps, not just raw text blobs.

Try restructuring the Data Action output to match this pattern:

  • Interaction Type: Set to web-chat or email depending on the original channel. Do not leave it blank.
  • Timestamps: Ensure start_time and end_time are in ISO 8601 format. Genesys Cloud rejects local timezones without explicit offsets.
  • Events Array: Map each Zendesk comment to a separate message event within the events array. Do not concatenate comments into a single string.

Here is a sample JSON structure for the events array that works reliably:

{
 "type": "web-chat",
 "start_time": "2023-10-01T12:00:00Z",
 "end_time": "2023-10-01T12:05:00Z",
 "events": [
 {
 "type": "message",
 "timestamp": "2023-10-01T12:01:00Z",
 "from": "customer",
 "text": {
 "content": "Zendesk comment content goes here"
 }
 }
 ]
}

Also, check the routing object. If you are backfilling data, the routing state is often irrelevant, but the API may still require a placeholder if the interaction type implies agent assignment. Use a static, inactive queue ID if needed to satisfy validation. Finally, run a small batch of 10 records first. Monitor the Data Action logs for specific field rejection errors. This approach avoids the generic 400 error by pre-validating the schema against the API documentation.

It depends, but generally…

  • The 400 error often masks underlying connectivity drops or SIP registration state issues rather than pure schema mismatches.
  • Verify that the BYOC trunk’s outbound routing is not blocking the API payload during high-velocity data pushes.

This is caused by schema mismatches between Zendesk’s flexible JSON and Genesys Cloud’s rigid interaction event definitions.

The 400 error usually stems from invalid timestamps or missing interaction types. Restructure your Data Action payload to strictly match the Interactions API schema before publishing. It’s all about precision in that mapping step.
