Getting Started

Set up API access and make your first MusePay integration decisions.

The MusePay API follows REST conventions. Endpoints use resource-oriented URLs, accept JSON request bodies, return JSON responses, and use standard HTTP methods and response codes.

Integration checklist

1. Review Supported Assets to confirm the currencies and networks required by your product.

2. Follow Authentication to generate your RSA key pair, upload the public key, and sign API requests.

3. Choose an API from the API Reference and review its request parameters and response objects.

4. Implement the relevant webhooks so your system can react to asynchronous order and card events.

5. Test the complete flow before enabling it for your customers.

Keep private keys in a secure server-side environment. Never expose them in browser or mobile application code.
