Errors

The REST API provides consistent, predictable error reporting, with HTTP status codes and detailed error messages.

The following error codes may be returned:

Error Code	Meaning
400 Bad Request	Indicates that the sent request is malformed, for example the request has wrong headers.
401 Unauthorized	Indicates that the Authorization header is missing in the request.
403 Forbidden	Indicates that the provided access key for the call is not valid.
404 Not Found	Indicates that the specified resource is not found, for example the user ID does not exist.
405 Method Not Allowed	Indicates that the API endpoint does not exist.
409 Conflict	Indicates that the request could not be completed due to a conflict with the current state of the target resource. For example, the target resource may have been modified concurrently.
415 Unsupported Media Type	Indicates invalid media type provided, for example sending a form encoded POST request body, instead of JSON.
422 Unprocessable Entity	Indicates that the request format is valid but the values do not meet the business rules. For example, a mandatory value is missing.
5xx	Any 5xx error code indicates a server-side problem and should be followed up with Nevis support.
