This guide will walk you through the process of creating an open client and connect to the UniPayment gateway. The integration is facilitated through a secure OAuth-based authorization flow, which ensures that all API requests are properly authenticated. For more details on the authorization process, please refer to our Authentication Guide.
​

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.

When creating an OpenClient, you have the option to enhance the security of your integration by specifying which IP addresses are allowed to access your client. While this step is optional, it is recommended for added security. 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.
