Payment Gateway Assistance
Budget: $30 – $250 USD
I’d like your help integrating a secure payment gateway into my application. The main goal is to configure, test, and deploy a fully functional checkout flow that accepts credit/debit cards and supports refunds. While I have not locked myself into a specific provider yet, PayPal, Stripe, or Square are all on the table; I’m happy to take your technical advice on which of those options best suits a fast, friction-free user experience.
Here’s what I need from you:
• End-to-end integration of the chosen gateway, including API configuration, webhooks, and sandbox/live environment switches.
• Clear documentation of all keys, callbacks, and error-handling routines so future maintenance is straightforward.
• A short walkthrough (screen share or concise video) showing test transactions succeeding and failing gracefully.
All development should follow the gateway’s official SDK guidelines, handle PCI-compliant tokenisation, and be built with clean, well-commented code. Once everything is in place and running smoothly I’ll sign off the milestone.
