Hackathon teams have two easy ways to test, learn, and build with the Open Finance APIs:
  1. Postman Collection — explore and send example API requests.
  2. Hackathon Starter Kit — run a full-stack sandbox app that demonstrates secure Open Finance usage.

​
🧰 Option 1: Postman Collection

The Postman Collection gives you a quick, hands-on way to experience the Open Finance API workflows. It includes a series of pre-configured requests that walk you through:
  • Creating consents
  • Exchanging tokens
  • Accessing account, payment, and product data
You can view request–response examples step by step to understand how each Open Finance capability works in practice. 📘 See setup instructions in the Postman Guide.

​
💻 Option 2: Hackathon Starter Kit

For those who want to build and test full applications, the Starter Kit provides a complete development environment. This starter kit gives teams a fast, full-stack head start for building applications with Open Finance APIs.
It includes:
  • A Node.js backend (Express.js) for API routing
  • Secure handling of sensitive data using crypto-js and jose (for JWTs and encryption)
  • Axios utilities for making API requests
  • A Vite-based frontend for interactive testing and visualization
You can run the kit locally, explore sample integrations, and extend it with your own ideas. 📘 Follow the setup steps in the Starter Kit Guide.

​
💡 Recommendation

If you’re new to Open Finance, start with the Hackathon Starter Kit.
It’s the easiest way to see the end-to-end flow, understand how authentication and API calls work together, and start building something real. Once you’re comfortable, use the Postman Collection to explore the APIs in more depth.
💡 Tip: Both tools use the same Open Finance Sandbox — choose the one that fits your workflow best!
