I’m ready to plug a new payment software API into our live website and already have the full documentation and keys on hand. What I need from you is clean, secure code that drops straight into our existing stack, handles the full checkout flow, and returns the usual success / fail callbacks so my team can log transactions and trigger order fulfilment. We are using Wix Velo (js-based) Deliverables: • Fully integrated payment endpoints with server-side validation • Front-end call examples (or drop-in components) for pages when payments are requested • Callback/webhook handling to update payment status in our database • Clear hand-off notes Everything should be tested in sandbox and then switched to live mode once we’ve verified successful end-to-end transactions. Let’s get this running smoothly.
