How do I fix the 401 Unauthorized errors hitting the /api/v2/external-crm/lookup endpoint every Wednesday at 08:00 PT? External CRM gateway keeps rejecting the token when Architect flow tries to pull customer history before queue assignment. IVR tree drops straight to default greeting instead of reading proper skill tags. Thirty agents sit idle while routing engine waits for a response that never arrives. System logs show OAuth handshake failing at step three. Vendor dashboard reports mismatch on client secret rotation schedule. Architect version updated to 2.4.1 last week. Lookup block still throws same status code. Queue dashboard turns red around 08:15 PT because transfer logic can’t validate caller profile. Coaching sessions get delayed since supervisors don’t see correct interaction history in wrap-up screen. External platform sends retry header, but flow just hangs on wait node. Console shows request payload contains correct account ID, yet response returns empty JSON object with unauthorized flag. Routing rules depend on that data to split calls between retention team and new business group. Without lookup succeeding, everything defaults to overflow queue. Vendor support ticket mentions certificate expiry on their side, but integration still expects valid bearer token from Genesys tenant. Flow designer highlights HTTP request step in orange after each failed attempt. We need routing to work without manual overrides. Error log repeats same timestamp pattern every business day.
Check the token scope on that service account. The external-crm/lookup endpoint is strict. If the client credentials grant didn’t include external-crm:read, you’ll get a 401 that looks like an auth failure but is actually a permission check.
Also, verify the Content-Type. It needs to be application/json. I’ve seen Architect flows default to form-urlencoded which breaks this specific call.
Here’s a quick check using curl to isolate if it’s the token or the flow config:
curl -X GET "https://api.nice-in接触.com/api/v2/external-crm/lookup?customerId=12345" \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
-H "Content-Type: application/json"
If that returns 200, the issue is in the Architect flow action configuration. Make sure the “Auth Profile” selected in the External CRM action matches the service account used to generate the token above. Don’t use the default profile if it’s tied to a user session that might have expired scopes.
