POS SDK

Bring Dropp into the checkout workflow you already have.

Dropp provides a simple REST-based interface that lets a POS platform integrate the Dropp payment flow directly into its existing point-of-sale experience.

Designed for existing POS systems

Dropp becomes another payment option inside the POS.

The POS keeps control of the checkout. Dropp handles the payment interaction and returns the result back into the transaction flow.

Initiate

The POS sends the payment request and transaction details to Dropp.

Present

Dropp returns the payment information needed to display the correct customer QR flow.

Authorize

The customer authorizes the payment through the Dropp payment experience.

Confirm

The payment status is returned to the POS so the checkout can complete normally.

REST-based interface

Keep the integration simple.

The POS does not need to recreate Dropp’s payment logic. It calls the Dropp interface at the appropriate points in the checkout and passes the invoice details needed for the customer experience.

AuthorizationCall Dropp to initiate and authorize the payment.

Invoice detailPush the correct transaction detail for display to the customer.

QR presentationDisplay the Dropp QR inside the existing checkout workflow.

StatusReceive the payment result back into the POS.
