Step 1: Create Open Client

For detailed information on authentication, please refer to our Authentication Documentation.

Click your name in the upper right corner of the admin panel. Select “API Management” from the dropdown menu.

To add an open client, click the “+Add” button on the right side

Enter your new open client name. Click the “Confirm” button once done.

Copy ClientId and ClientSecret after creation.

Adding IP Whitelist During OpenClient Creation

As part of the OpenClient creation process, it’s important to secure your connection by specifying which IP addresses are allowed to access your client. To add an IP to the whitelist, follow these steps:

Navigate to the "Action" menu located on the right side of the interface, click on "IP whitelist".

In the provided field within the pop-up window, carefully enter the IP address you wish to whitelist.

Step 2: Create Payment App

PaymentApp empowers merchants to customize their online store experience by setting callback addresses, configuring checkout page language and style, choosing invoice handling modes, and accepting a wide range of cryptocurrencies. This versatile tool ensures flexibility and security for businesses of all sizes, enabling seamless transactions and customer satisfaction.

Create the payment app and get AppId.
