Environment
nocnoc runs a single live environment. Every request you make is processed as a real transaction against real data.Authentication
nocnoc uses API keys. Include yourSELLER_KEY in the X-Api-Key header on every request. Your key is provided by the nocnoc team — contact your Account Manager if you don’t have one yet.
Every request must also include the Content-Type: application/json header. Requests without it will return a 415 Unsupported Media Type error.
No IP allowlist configuration is required. The API accepts requests from any origin IP address.
Your first request
200 response confirms your key is valid. A 401 indicates the key is missing or incorrect.
