Error Codes

To handle errors that occur during request execution, it is necessary to analyze the HTTP response status or the presence of a special JSON structure in the response:

{
            "error": "ERROR_HANDLER_ALREADY_EXIST",
            "error_description": "Handler already exists!"
        }

Name `type`	Description
error `string`	String error code. It may consist of digits, Latin letters, and underscores
error_description `error_description`	Textual description of the error. The description is not intended to be shown to the end user in its raw form

A list of specific error codes that occur when calling a particular REST API method is described for each method separately. There is also a list of system errors that are independent of the logic of a specific REST API request.
