Test API Key

Mileston makes it easy for you to simulate real-world crypto payments using our Test API Key. Since we’re a crypto payment gateway, we understand the importance of testing your setup without worrying about real money. That’s why we offer seamless integration with testnet environments across supported blockchains.

Supported Blockchains​

Mileston currently supports the following blockchains for payments, with more coming soon:

  • Sui
  • Polygon
  • Ethereum
  • Base

Don’t sweat the technical details! We’ve done all the heavy lifting for you. You just need to focus on building your application while Mileston handles the blockchain complexities.

What Is a Test API Key?​

A Test API Key allows you to create payments on the testnet and use faucet tokens to mimic real payments. It’s a risk-free way to test the integration without monetary value. 🎉

A sample test API key looks like this:

Using a test API key, you can:

  • Create test payments and invoices.
  • Verify how payments flow in your app.
  • Simulate user interactions with mock payments.

How to Get Your Test API Key​

Refer back to the Why Use API Keys? page for detailed instructions on where to find your API keys. Spoiler: It’s in the Developers tab of the dashboard at business.mileston.co!

Why Testing Matters​

Before you go live on the mainnet, testing ensures your app is free of bugs and runs smoothly. Plus, you’ll get to flex your coding skills with confidence! 🧑‍💻✨
