CXone Personal Connection API: 403 Forbidden on outbound call trigger via Python

NICE CXone API & Integrations

  • I’ve spent hours trying to figure out why my Python FastAPI proxy is consistently receiving a 403 Forbidden error when attempting to trigger an outbound call using the CXone Personal Connection API, despite having valid OAuth tokens.

  • Here is the relevant httpx async client configuration and request payload I am using to invoke the endpoint:

async def trigger_personal_call(token: str, contact_id: str):
 url = "https://api.nice-incontact.com/uxapi/v1/personal-connections/outbound"
 headers = {"Authorization": f"Bearer {token}", "Content-Type": "application/json"}
 payload = {
 "contactId": contact_id,
 "phoneNumber": "+15550199",
 "type": "voice"
 }
 async with httpx.AsyncClient() as client:
 response = await client.post(url, headers=headers, json=payload)
 return response.status_code

  • The error response body indicates “Insufficient permissions for the requested action,” which is puzzling because the same token successfully queries user profiles via the standard REST API.

  • I have verified that the application scope includes cxone:personal-connections:write and that the impersonated user has the necessary role permissions in the CXone admin console.

  • Is there a specific header or sub-scope required for the Personal Connection endpoints that is not documented in the standard OpenAPI spec, or am I missing a prerequisite configuration step in the code?
