[1/2] Creating API user
X-Reference-Id : 650cc539-4975-46e6-a996-d75880580b9d
Response : HTTP 500
Body : { "statusCode": 500, "message": "Internal server error", "activityId": "5c51b72c-68dd-433d-ad6c-b2195900795b" }
FAILED at step 1 — MTN rejected API user creation.
Diagnosis:
MTN's backend returned an internal error.
This is almost always one of:
• No registered developer application on your
MTN profile (register one at
https://momodeveloper.mtn.com/developer).
• An MTN-side sandbox outage (transient — retry in
an hour, or check their community forum).
Copy the activityId from the body above and include it
in any support ticket — it is MTN's server-side trace.
