Status Codes

The Senmo API uses conventional HTTP response codes to indicate the outcome of an API request. Response codes can be grouped into the following categories:

• 2xx: The request was successful.

• 4xx: An error occurred due to the information provided, e.g., missing or incorrect parameters.

• 5xx: Those errors are returned if there was an error in Senmo servers.

Senmo API error responses all follow a standard format. They include the HTTP response code, the reason for the error, and a unique ID for use with Senmo customer support.
