The REST API is designed to use HTTP response codes to indicate status. The body of the response will also include more information.When you want to verify a customer phone you start by requesting a verification code for that customer phone number.The verification code is valid for 10 minutes. Subsequent calls to the API within the expiration time will send the same verification code.
