Where to find the API & SDK docs
Updated June 29, 2026
These support articles cover Passmint as a product. For building against it in code, the full developer documentation lives at passmint.com/docs. Here's what you'll find there and where to start.
Start here
- Quickstart — issue your first pass from the API in a few minutes. The fastest way to see the API work end to end.
Reference
- REST API reference — every endpoint, parameter, and response, including issuing, updating, and voiding passes and managing templates.
- Node SDK — the official JavaScript and TypeScript library, with typed methods for everything in the API.
- Webhooks reference — the event payloads, signature verification, and delivery behavior for receiving events in your own system.
Open source
- The
passmintpackage is open source, so you can read exactly how the SDK works and contribute if you'd like.
You'll need an API key to follow the quickstart. Create one in Developers → API
keys, and use a pmk_test_ key while you build. See
API keys: test vs live.
