Status codes

Stenn uses conventional HTTP response codes to indicate the success or failure of an API request. In general: Codes in the 2xx range indicate success. Codes in the 4xx range indicate an error that failed given the information provided (e.g., a required parameter was omitted, a charge failed, etc.). Codes in the 5xx range indicate an error with Stenn’s servers (these are rare). Error responses contain more detail about the error in the response body, in the "message" property.

Code	Description
200 - OK	Everything worked as expected.
400 - Bad Request	The request was unacceptable, often due to missing a required parameter.
401 - Unauthorized	Missing or invalid API credentials.
402 - Request Failed	The parameters were valid but the request failed.
403 - Forbidden	The API key doesn't have permissions to perform the request.
404 - Not Found	The requested resource doesn't exist.
409 - Conflict	The request conflicts with another request (perhaps due to using the same idempotent key).
429 - Too Many Requests	Too many requests hit the API too quickly. We recommend an exponential backoff of your requests.
500, 502, 503, 504 - Server Errors	Something went wrong on Stenn’s end. (These are rare)
