Creating FIAT payment

XAMAX provides the ability to perform end-to-end payments via payment links or via payment forms. To use these solutions, no additional integration into merchant systems is required. All solutions are implemented on the XAMAX side.

• when using the link, XAMAX generates payment details for the country (or currency) of the buyer and provides the merchant with a link or QR code for payment. The merchant can send a link to the buyer for payment
• when using the payment form, the buyer will be redirected to the XAMAX payment form to make a payment

For both methods, XAMAX keeps track of when the buyer makes the payment and notifies the merchant of this. The notification can be received via the callback URL or the payment status can be tracked in the merchant's personal account.

Creating FIAT payment link

Payment links provides a way to easily integrate e-commerce purchases to your online or offline business

Merchant can accept payments through any channel or device. All you need to do is send the Payment link to the customer, and it will take them to a XAMAX's payment form for them to complete the payment. Merchant can send Payment link by email or in text message or can show QR code for payment on any screen!

tip

Links can only be used to accept one-time payments, and expire after 24 hours by default.
