Experienced WordPress & PHP Developer Required

We are looking for an experienced WooCommerce developer to implement a secure cross-domain payment flow between two independent WordPress WooCommerce websites.

Required Payment Flow

Website A (Primary Store): Customers place orders without a directly enabled payment gateway.

Website B (Payment Store): Handles payment processing through Stripe Checkout.

Customers are redirected from Website A to Website B to complete payment.

After payment, customers return to Website A, where the order status is automatically updated based on verified payment results.

Payment confirmations and transaction details must be recorded accurately.

Key Requirements

Secure transfer of order details and payment amounts between websites.

Dynamic Stripe Checkout integration on Website B.

Reliable return URL handling and server-side payment verification.

Webhooks/API integration to prevent duplicate orders and incorrect payment statuses.

Strong security and data integrity throughout the process.

Website B must process payments exclusively through its own authorized checkout flow, without exposing Stripe to unauthorized external payment requests
