Payment API Integration | Stripe, PayPal & Webhooks by Muhammad Zulqarnain SafdarPayment API Integration | Stripe, PayPal & Webhooks by Muhammad Zulqarnain Safdar
Connect your website or web application to payment providers with a carefully scoped integration for Stripe, PayPal or another supported payment API.
WHAT I CAN IMPLEMENT
Checkout flows, one-time payments, subscriptions, customer billing portals, payment status updates, signed webhooks and provider API connections. Stripe Connect, refunds and more complex flows can be included after review.
DELIVERABLES
Integration source code, server-side validation, error handling, webhook processing, testing of agreed sandbox scenarios and configuration or handover notes. Idempotency and event handling are included where required by the agreed flow.
PROCESS
Share your stack, provider, checkout requirements and existing issues. We confirm the payment flow, scope, timeline and price before implementation. Testing starts in the provider sandbox; live activation is coordinated with you.
You need an eligible provider account and required API access. Provider approval, processing fees and third-party charges are separate. Credentials should be shared securely.
