Point of Sale (POS) Flow

Flow description

  1. Within Point-of-Sale (POS) system, the sales person chooses the Laybuy payment option.
  2. The POS creates a new Laybuy order by making a request to the Laybuy Create Order interface and passes the order details, including a unique merchant reference and the customer's mobile phone number.
  3. If the request fails, an error is displayed within the POS.
  4. If the request is successful, the customer is sent a link to the payment process via an SMS message.
  5. The POS uses the unique merchant reference to periodically call the Get Order interface to check for a completed order.
  6. The customer proceeds through the payment process on their mobile device.
  7. The POS then polls the Get Order interface. If the payment fails after a POS defined timeout or is cancelled, the POS displays an error and allows a retry, or alternative payment method
  8. If the payment is successful, the next call to the Get Order interface will return the details of the order. The sale can then be processed.
