PayFast API Integration & Commission-Splitting for WordPress

We are looking for an expert WordPress and API developer to integrate the PayFast payment gateway directly into our custom-built WordPress plugin (no WooCommerce required) for our platform, hash-move.com.

The project budget is strictly fixed at $10 USD for this milestone, focusing on clean, secure, and efficient implementation.

Key Deliverables & Scope of Work:
1. PayFast API Integration: Direct integration into our custom WordPress plugin, supporting local payment methods.
2. Checkout & Security: Secure payment verification handling before confirming bookings.
3. Commission-Splitting Logic:
- Admin settings dashboard to manage and update the platform commission percentage.
- Automatic calculation of Hash-Move's platform commission and the traveler’s share.
4. Dashboard & Transaction Status: Payment records and transaction statuses visible in the admin dashboard.
5. Notifications: Email notifications for successful and failed payments.
6. Testing: Sandbox testing followed by production deployment.
