I have built several Node.js middleware services integrating Stripe webhooks and Shopify APIs, including handling manual capture workflows and idempotent webhook processing. I’ll design the PostgreSQL schema focused on operational data only, avoiding PHI storage and implementing secure secret management and webhook signature verification as required. For this project, I’ll create middleware to receive and verify Jotform, Stripe, Shopify, and telehealth provider webhooks, transforming intake data without storing sensitive info. The Stripe payment flow will handle authorization at checkout, capture after provider approval, or cancellation on rejection, ensuring retries and race conditions are covered. Could you share the telehealth platform’s API docs or webhook format? Any preferences on error handling or logging tools? Also, are you expecting this deployed on a specific platform (AWS, GCP, etc.)? I can deliver a production-ready Node.js/Express service complete with schema migration scripts and setup documentation.

Hello, I can build the backend-only Node.js/Express middleware required to integrate Shopify (API/webhooks only), Jotform, Stripe manual capture, and your telehealth provider platform. The service will handle verified webhooks, Stripe authorize → capture → cancel flows, idempotency and retry logic, and state transitions for patients, orders, and approvals. I’ll design a PostgreSQL schema that stores only operational identifiers (no PHI), implement secure SSO token handling, and follow strict logging and secret-management practices. No frontend or Shopify theme work—pure API orchestration, event-driven logic, and production-ready backend code, delivered with migrations and setup documentation. Quick check before starting: Is the telehealth provider approval flow webhook-driven only, or do you also expose polling endpoints? Happy to connect on chat and review the technical spec.
