Status Codes

The Senmo API adheres to standard HTTP response codes. A response in the 2xx range indicates a successful request. A 4xx error signifies an issue with the input data (e.g., an incorrect routing number). In cases where an error reason is provided, your application may be able to handle these errors programmatically. A 5xx error indicates a server-side issue, which we will address as a priority.

Below is a table outlining the status codes and their meanings.
