Overview

The AeroSync API provides error codes with their respective messaging indicating why an error ocurred during processing time.

The Basics

The error codes are sent as part of the response body indicating an error from status code and body. The code will always start with AC followed by a designated 3 digit number depending on the error, followed by a message describing the error.

{
    "error": {
        "code": "AC-204",
        "message": "No account information available, please select another bank."
    }
}
