What is …?

In traditional finance, a chargeback is a reversal of a credit card payment: a customer pays you but then requests the money back, and the bank enforces you to comply.

This may happen for a variety of reasons: if a cardholder has been charged for an item they never received; if there was a mistaken charge by the merchant; if the consumer wanted to return the item but didn’t do that on time, and so on.

An invoice is a hassle-free way to integrate NOWPayments in your online store. It’s a small box where all the necessary information about the payment is collected: the deposit address, the currency, and the sum.

How to Use Invoices:

1. Create an invoice for payment in your Account.
2. Put it on your website or send it to your client.
3. Now, you have a handy payment tool for your customers.
4. You are ready to accept crypto payments

NOWPayments API is a set of code that allows you to implement a crypto payment gateway on your online store, casino, or to do mass payouts in cryptocurrency. Follow the links to find the documentation for each and contact us — we will guide you through the installation process!

Nowadays, a lot of major companies (PayPal, Tesla) have been working on adopting Bitcoin payments as well as other cryptocurrencies. The easiest way to accept cryptocurrency is to use a crypto payment processor. There are two types: custodial and non-custodial ones.

Instant Payment Notifications (IPN), or callbacks, are the way we notify you of the transaction status updates. This tool is available if you’ve integrated with NOWPayments through the API.

IPNs are a little more sophisticated than regular push notifications, but once you set them up, they will become a helpful tool to get instant payment updates.

The Sandbox is a way to test our API without making any real transactions. Merchants get to test any payment case they want and get the full data from our API describing it.

To be approved, transactions require signatures. Some wallets need only one signature for authorization. There are wallets shared by multiple users too, which require multiple signatures.

There are several types of Bitcoin addresses. To get a new Bitcoin address, all one needs to do is download a Bitcoin wallet. You can enter your address when signing up for a NOWPayments account, to receive Bitcoin payments.
