Subscribe to 40+ events across orders, products, payments, and customers. HMAC-signed payloads with automatic retry.
Official Node.js and Python clients. Community SDKs for PHP and Ruby. All open-source and MIT-licensed on GitHub.
Build apps merchants install in one click. Scoped permissions, token refresh, and a full sandbox environment to test in.
Create a private app in your Numu dashboard — credentials are issued instantly.
