This guide will walk you through the process of integrating NOWPayments gateway as a payment method, enabling smooth and secure transactions.

Prerequisites

Before proceeding, you will also need to create a NOWPayments (https://nowpayments.io) account and install the NOWPayments app on your MetaFox site.

Configure NOWPayments in MetaFox AdminCP

Log into your site with Admin user and go to AdminCP > App Settings > Payment > Gateways. Then Edit the NOWPayments option.

On the Edit form, configure fields as below

1. Title: the gateway title shown to end-users. This can be freely configured according to your preferences.
2. API Key: must be configured after generating API credentials on NOWPayments. Please visit the following URLs to obtain your API key
   • Production: https://account.nowpayments.io/store-settings#keys
   • Sandbox: https://account-sandbox.nowpayments.io/store-settings#keys
3. IPN Secret: must be configured to verify IPN callbacks sent by the gateway, preventing frauds. The IPN secret is available after configuring Instant Payment Notifications on NOWPayments. 
   • Production: https://account.nowpayments.io/store-settings#notifications
   • Sandbox: https://account-sandbox.nowpayments.io/store-settings#notifications
   • The IPN handler should be pointed to https://YOUR_DOMAIN/api/v1/nowpayments/notify 
4. Active: Check to enable the gateway to allow end-users to make payments using NOWPayments.
5. Test Mode: Check to enable test mode (sandbox) to fully test the workflow without affecting real balances.
   • Ensure that you have configured the correct API and IPN credentials according to  your preferences.
