Question 3

What are NOWPayments’ fees?

Accepted Answer

NOWPayments has the following fee structure in place: For each payment, there’s a small 0.5% default service fee. If you’d like to accept all 300+ cryptos and settle them down in a certain asset, you can look into the auto-conversion feature. In this case, an additional 0.5% service fee would come into place. For Custody users, conversions within the custody balance incur a 0.5% service fee without any network fees. Therefore, the max service fee for a crypto-to-crypto transaction is 1%. Please note that this does not include network fees. Both options are instant and do not require manual control from you or your team. By the way, there are no service fees for integration, support, further account optimization, and even mass payouts 🎉 Give less, get more - NOWPayments is on the lookout for your benefits!

Question 6

What is an IPN?

Accepted Answer

Instant Payment Notifications (IPN), or callbacks, are used to notify you of transaction status updates. This tool is accessible if you’ve integrated with NOWPayments via the API. IPNs, more advanced than regular push notifications, provide instant payment updates once set up and are sent to your server as HTTP queries. To begin with IPN, obtain a Secret key from the Store Settings tab in your Account to enhance security and verify transaction status authenticity. For setup guidance, refer to the API docs.
