SDKs

Implementation Code

Ready-to-use implementation code for integrating YardPay Pro into your web, mobile, and server applications. Each SDK wraps the REST API with idiomatic patterns for its platform — just copy the files into your project.

How It Works

Each SDK provides complete, copy-paste implementation code. No package managers needed.

1. Copy the files

Each SDK is a small set of files with the API client, typed models, and service wrappers.

2. Set your API key

Initialize the client with your API key. Use sk_test_ for sandbox.

3. Call the API

Use the typed service methods to create invoices, process payments, manage subscriptions, and more.
