C# (pronounced as C sharp) is a general-purpose, object-oriented programming language. It is one of the most popular languages used for developing desktop and web applications.
You can easily integrate crypto payments into your own website or app with our UniPayment .Net SDK, after installation you can start accepting crypto-payments.
A .NET client for the UniPayment Client API.
This SDK provides a convenient abstraction of UniPayment's Gateway API and allows developers to focus on payment flow/e-commerce integration rather than on the specific details of client-server interaction using the raw API.
Before using the UniPayment API, sign up for your API key.
If you want to use the Sandbox, sign up here.
nuget install UniPayment.Client
using UniPayment.Client;
client = UniPaymentClient(AppId, ApiKey);
Sandbox is used in the same way with is_sandbox as true.
using UniPayment.Client;
client = UniPaymentClient(AppId, ApiKey);
