Developer Quick Start

This section covers the core technical concepts you need to integrate with the API. Whether you're building your first integration or need a reference for specific implementation details, these guides will help you build secure, reliable, and scalable applications.

What You'll Learn

These guides walk you through the fundamental patterns and protocols used throughout the API:

Authentication

Learn how to authenticate your API requests using API keys and tokens. This guide covers credential management, authentication headers, and security best practices.

Key topics: API keys, bearer tokens, credential rotation, security considerations


Request Signing

Understand how to cryptographically sign your API requests to ensure authenticity and integrity. Request signing adds an additional layer of security beyond authentication.


Idempotence

Prevent duplicate transactions and ensure safe retry logic using idempotency keys. Learn how to make your integrations resilient to network failures and timeouts.


Pagination

Efficiently retrieve large datasets using cursor-based pagination. This guide explains how to iterate through list endpoints and handle large result sets.


Subscriptions

Set up webhooks to receive real-time notifications about events on the platform. Subscriptions enable event-driven architectures and automated workflows.


Integration Checklist

Before you start building, make sure you have:

  • API credentials (sandbox and/or production)
  • Development environment configured
  • Webhook endpoint URL (for subscriptions)

Quick Integration Flow

  1. Authenticate - Set up your API credentials and test authentication
  2. Make your first request - Create a test resource using proper request signing
  3. Handle responses - Implement error handling and idempotency
  4. Set up webhooks - Subscribe to relevant events for your use case
  5. Test thoroughly - Use sandbox environment before going live

Next Steps

Support

If you run into issues or have questions:

  • Check the API Documentation for detailed endpoint references
  • Review error codes and troubleshooting tips in each guide
