# Payment API
If you want to provide the ability for someone to pay with WAVES or any other WX Network tokens, you can use our Payment API.
# Process
- You set up a button on your site which triggers the creation of an URL and a redirect to it.
- A user decides to buy something and the user presses that button.
- After that, the user is redirected to the WX Network app with a payment parameters window.
- The user modifies those parameters if possible and submits the form.
- If everything's okay, the user is redirected back to referrer.
- Referrer is provided with transaction ID which can be checked if it is in the blockchain.
If the user interrupts the process, he stays on the WX Network app page.
