Stripe Subscription and Pre-authorisation Integration for FlutterFlow App
Budget: £20 – £250 GBP
We have an Uber-like app built in FlutterFlow that lets you call an ambulance. I need help with the below 2 tasks that are to do with handling payments:
1. Set Up Monthly & Yearly Subscriptions via Stripe:
Integrate Stripe into the FlutterFlow app to handle monthly and yearly subscriptions without using native in-app purchases or external website links. Use Voi (e-scooters sharing app) as a reference for how subscriptions are handled.
2. Automate Pre-authorisation and Final Charges for Ambulance Service
Implement a system to:
- Pre-authorise an initial amount (e.g., $100) instead of charging it upfront.
- Calculate the final cost based on time spent with the patient, type of vehicle (ambulance or paramedic car), and time/day of the week (higher rates for weekends or nights).
- Only charge the final calculated amount after the ride is completed, adjusting the pre-authorised amount accordingly.
- Release the unused portion of the pre-authorisation after the final charge.
- Handle full pre-authorisation releases if the service is cancelled before dispatch.
Need to be familiar with the below:
FlutterFlow, Flutter, Dart, Stripe API integration, Firebase, Handling webhooks for Stripe events, Backend logic for processing final charges based on service details.
The app is called FlashAid and is available on App Store and PlayStore.
We are looking for a fair price and a developer who is interested in working with us long-term, as we’ll have more tasks after this. Please don’t say these features will cost $200 and take 2 weeks! I’ve worked with developers who were fast and cost-efficient, and I expect the same.
