Job Description
I have a FlutterFlow mobile app where the frontend logic is confirmed working and sends the correct payment amount.
The issue is in my backend API , hosted on Vercel) that creates Stripe Checkout sessions.
Regardless of the amount sent from FlutterFlow, Stripe is always charging $10.
I need an experienced Stripe backend developer to:
Debug an existing API (Vercel serverless function)
Inspect the request payload coming from FlutterFlow
Identify where the amount is being overridden / defaulted
Ensure Stripe Checkout charges exactly the amount passed in
Remove any hard-coded values or fallbacks
Make the API safe and production-ready (no rebuild required)
Important
FlutterFlow does NOT need to be changed
UI, split logic, and messaging are already correct
This is a backend-only Stripe issue
Contract duration of less than 1 month.
Mandatory skills: Stripe, Stripe API, , Vercel, API Development
