WL Crypto Payments

Saferpay also offers the possibility to pay via the Bitcoin and Etherum crypto currencies. The following chapter will cover the activation and integration of this payment method.

General requirements

The handling of Crypto currencies with Saferpay requires:

• A corresponding license and thus a valid identification with a username and password for the Saferpay system.

• Availability of at least one active Saferpay terminal via which payment can be carried out and availability of the associated Saferpay TerminalId.

• In general, the payout of transactions made via cryptocurrencies will happen in CHF or EUR. However, payments in EUR are currently only possible in Belgium and Luxembourg. Any other currency, or payout to a cryptocurrency wallet, is not supported!

For WL Crypto Payments activation on the Saferpay terminal and the necessary contract, please contact your Saferpay sales contact.

Technical requirements

The general integration of Crypto Payments can only be done via the Payment Page and requires the following things to be noted:

• API SpecVersion 1.22+

Handling Refunds

Refunds are a challenge, as the Blockchain itself does not support them. To circumvent this issue, Bitcoin Swiss offers a process to handle refunds, via a different way.

Refunds are generally executed normally, via the Saferpay API (or the Backoffice), as you would expect. However, while normal refunds either report an AUTHORIZED or CAPTURED status, WL Crypto Payments introduces a thrird status: PENDING.

If a refund is requested, Saferpay will forward this request to Bitcoin Swiss, which will then contact the payer, using the e-mail, which must be provided during the payment. The refund is then processed as a normal bank-transfer and not via the crypto currency.

Due to the fact, that this process takes time, every refund will first have the status PENDING, which will remain, until the refund has been processed correctly.

Once done, Saferpay will recieve a notification and change the status of the refund to CAPTURED.

Querying the transaction status via API

To automatize this process, you first need to set the PendingNotification.NotifyUrl option, available for the Transaction/Refund. Once Saferpay recieves a status-update, the NotifyUrl will be called, enabling you to query the final status of the Refund.

The status of a WL Crypto Payments refund can be queried with the JSON API. The corresponding function is the Inquire Interface.

Remember to reference the refund, not the original transaction, that has been refunded!

This process is basically the same, as with the Notification URLs, within the Payment Page process and follow the same rules.
