API Integration

Integrate HashNut payments into your application using the REST API.

Overview

HashNut provides a comprehensive REST API for payment integration. All API requests use HMAC-SHA256 signature authentication.

Quick Start

1. Get API Credentials
2. Authenticate Requests
3. Create Orders
4. Handle Webhooks

API Endpoints

• Orders: Create and query orders
• Configuration: Get chain and token info
• Webhooks: Receive payment notifications

Authentication

All API requests (except query endpoints) require HMAC-SHA256 signature authentication.

See Authentication Guide for details.

Code Examples

See Quick Start Guide for complete examples.

Best Practices

1. Secure Credentials: Never commit API keys to version control
2. Error Handling: Handle all error codes gracefully
3. Idempotency: Make operations idempotent
4. Logging: Log all API interactions
