Point of Sale

Integrating a point of sale (POS) terminal with Centrapay APIs allows merchants to accept payment via any Centrapay-enabled apps without installing additional POS hardware or software.

Core Requirements

Centrapay POS integrations must be able to create , void and refund Payment Requests on behalf of Merchants.

The POS authenticates against Centrapay APIs using a single “merchant terminal” API key.

• Requesting Payment MUST connect with the patron using either the QR Code Flow for Merchants or the Barcode Flow for Merchants .
• Merchant integration errors MUST be handled correctly.
• Initiating refunds MUST be performed using the id or shortCode Payment Request fields.
• The id or shortCode MUST be made available to the patron (e.g. on paper print-out).
• Paid Asset Types MUST be made available for merchant Transaction Reporting .

Optional Protocol Extensions
