POST /api/v2/integrations fails with 403 during Zendesk migration

NICE CXone API & Integrations

Having some issues getting my configuration to work… trying to replicate Zendesk’s robust API access via Genesys Cloud integrations. The POST to /api/v2/integrations returns a 403 Forbidden, despite admin rights. In Zendesk, this was straightforward, but GC seems stricter. The payload mimics a standard OAuth setup. Is there a specific permission set I am missing for the migration user?

Thanks for the help.

Check your service account’s role assignments and the specific scope of the OAuth client credentials being used for the integration creation. A 403 on /api/v2/integrations almost always stems from insufficient privileges on the user token initiating the request, rather than the payload structure itself. Genesys Cloud enforces strict RBAC for integration management, distinct from general admin rights. The user performing the POST requires the integration:admin permission, which is often missing from standard “Super Admin” roles if custom role hierarchies are in place.

Ensure the following steps are completed before retrying the migration script:

  • Verify the service account holds the Integration Admin role or a custom role explicitly granting integration:admin and integration:read scopes.
  • Regenerate the OAuth client credentials using a user with confirmed integration management privileges. The previous token may have been bound to a user with restricted scope.
  • Validate the payload against the IntegrationRequest schema. Specifically, ensure the configuration object matches the expected structure for Zendesk (e.g., correct ticket_field_mappings format).
  • Test the endpoint via Postman using the new token to isolate API issues from migration tooling errors.

If the 403 persists, check the X-Genesys-Request-Id header in the response and cross-reference it with the audit logs. This often reveals hidden permission denials related to cross-tenant restrictions or IP allow-listing. The documentation for Data Actions integration setup notes that webhook targets must also be accessible from the Genesys Cloud network, so ensure your Zendesk instance isn’t blocking outbound connections from Genesys Cloud IP ranges. This network-level block can sometimes manifest as a 403 if the integration validation step fails silently.

Hello.

Check the OAuth client scopes. The admin role is not enough. You need integration:admin and integration:write in the token. Also, verify the service account has the correct role assignment. The 403 error usually means the token lacks specific permissions, not just general admin rights. Try regenerating the token with these scopes.
