1. When a customer begins to check out, you send a sale request to `Cybersource` and receive one of these possible statuses:
   * `FAILED`: The sale cannot be completed.
   * `PENDING`: The sale request is accepted but is not completed. Send the check status request to retrieve status updates.
2. You send a check status request to `Cybersource` to verify the sale status and receive one of these statuses:
   * `ABANDONED`: The customer did not complete the payment using the redirect URL.
   * `FAILED`: The sale request failed. A failed request can be due to either a rejection or a technical error.
   * `PENDING`: The sale request is accepted but is not completed. Send the check status request as often as necessary to obtain the information that you need.
   * `SETTLED`: The sale request is settled for the requested amount. When the settled amount is deposited into the merchant's bank account, the status updates to `FUNDED`.
