Overview
This Node.js reference implementation exists because BillDesk's official documentation stops well short of a working integration. It covers the create-order flow, JWT signing, request construction, and the handoff to the frontend SDK in a form that Node.js teams can adapt directly without reverse-engineering the implied behavior.
The problem
BillDesk is a major payment gateway used across Indian fintech products, but its Node.js guidance is incomplete. Teams lose significant time reconstructing the JWT signing flow, order request structure, and SDK handoff from partial examples and support threads.
What I built
The guide provides a complete, security-aware Node.js walkthrough of the create-order flow. Each step — JWT construction, payload signing, order request, and frontend SDK trigger — is shown with working code and enough commentary to make the security-sensitive steps explicit rather than implicit.
My role
Sole author of the integration example, technical walkthrough, and security-conscious implementation pattern. The guide was written to reflect what a senior engineer would actually ship, not just what works in a demo.
Biggest challenge
Making the JWT signing flow and security-sensitive setup patterns explicit without oversimplifying requires a careful balance between accessibility and accuracy. The goal was a guide readable by a Node.js generalist, not just a payments specialist.
