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
idorshortCodePayment Request fields. - The
idorshortCodeMUST be made available to the patron (e.g. on paper print-out). - Paid Asset Types MUST be made available for merchant Transaction Reporting.
