Errors ​

Q2 CS API uses HTTP response status codes to indicate the success or failure of your API requests. If your request fails, Q2 CS API returns an error using the appropriate status code.

In general, there are three status code ranges you can expect:

• 2xx success status codes confirm that your request worked as expected
• 4xx error status codes indicate an error because of the information provided (e.g., a required parameter was omitted)
• 5xx error status codes are rare and indicate an error with Q2 CS API's servers
