Architect IVR Transfer Fails with 403 During Zendesk Migration

Architect & Flows
1

Can’t quite understand why the Transfer to Queue block fails with HTTP 403 Forbidden when migrating from Zendesk Talk. The flow works in the simulator but breaks in production.

  1. User enters IVR and selects option 1.
  2. Architect attempts transfer to Queue ID abc-123.
  3. System returns 403 Forbidden instead of ringing agents.

The Zendesk equivalent was just a simple tag assignment, so why is GC blocking the queue injection?

Check your OAuth token scope and the specific permissions assigned to the integration user making the HTTP request in Architect. A 403 Forbidden during a transfer operation often points to a misconfiguration in the authentication credentials rather than the queue ID itself, especially when migrating from a system like Zendesk that handles permissions differently.

In Genesys Cloud, the flow execution context relies on the permissions of the user or application token used for the HTTP request step. If you are using an OAuth Client Credentials flow, ensure the client has the routing:queue:write and routing:conversation:write scopes. The simulator often uses your personal admin credentials, which bypasses these stricter checks, leading to the discrepancy you are seeing in production.

Verify the token endpoint configuration in the HTTP request block. It should look something like this:

{
 "endpoint": "https://{{env}}.mygenesys.com/api/v2/oauth/token",
 "method": "POST",
 "body": {
 "grant_type": "client_credentials",
 "client_id": "{{client_id}}",
 "client_secret": "{{client_secret}}"
 }
}

If you are using a Data Action to trigger the transfer, ensure the Data Action is configured to use the correct authentication method. Sometimes, the default system token lacks the necessary write permissions for queue operations.

Additionally, review the queue’s outbound settings. If the queue is configured to only accept transfers from specific skills or groups, and the IVR context does not map those skills correctly before the transfer attempt, the platform may return a 403. Cross-reference the queue’s configuration with the user profile settings in the IVR flow.

Finally, check the audit logs in Genesys Cloud for the specific interaction. The detailed error message in the logs will often specify exactly which permission was denied, allowing you to adjust the OAuth scopes or user roles accordingly. This level of granularity is crucial for debugging authentication issues in production environments.
