Error codes

The Ecommerce API returns error codes and messages when a request contains invalid or incomplete data and Clover cannot process the request. These issues can be divided into two general categories:

Errors that should be addressed by your app's logic (if you are integrating with the API only)
Errors that should be handled at runtime (iframe and API integrations)

Errors you may encounter are explained the in the following sections.

API only errors

You can prevent these errors by checking for the described issues in your application before submitting the API request.
