Lovable/React Developer — API & Webhook Integration for Telehealth Platform (MDI White-Label)

I'm the owner of BiophysiqMD, a telehealth company with a live site built on Lovable (React/TypeScript frontend, Supabase backend). We're integrating with MD Integrations (MDI), a physician network/telehealth platform, using their White-Label integration model. What's already handled by MDI (not part of this project): - Patient intake forms, chat, and notifications — hosted by MDI, embedded/branded under our domain - Clinical protocols and provider review — managed by MDI's physician network - E-prescribing, routed through MDI as a proxy to DoseSpot - Pharmacy fulfillment routing once a prescription is approved What we need built 1. Voucher Endpoint integration — connecting our Lovable site's product catalog to MDI's API for our formulary of roughly 70-90products 2. Checkout/payment logic: authorize (hold) payment at checkout using Stripe's manual-capture PaymentIntent, then capture only once MDI's `case_approved` webhook confirms provider approval. This also needs to handle the decline case (void the hold) and the authorization-expiry case (Stripe holds typically expire after ~7 days) if approval takes longer than that. 3. End-to-end testing across the full product catalog: product selection → case creation → provider approval → payment capture → pharmacy handoff MDI API docs: https://documenter.getpostman.com/view/14212272/2s8Yt1r9B8 MDI white-label patient journey (Figma): https://www.figma.com/board/1KHuZxh640OzX72JahKPNp/E2E-Patient-Journey?node-id=0-1&p=f Please include in your proposal: - Relevant experience with Lovable/Supabase and third-party API/webhook integrations, ideally healthcare or another regulated industry - A scoped estimate (timeline + cost) for the work above - Your take on realistic timeline given ~70-90 products — we've gotten conflicting estimates elsewhere and want an honest read
