Integrate PayFast for South African Online Payments
Your customers are ready to pay. But botched ITN callbacks, broken recurring billing, and split-payment logic that miscalculates commissions are costing you completed sales every single day.
We build PayFast integrations that just work, from the first card tap to the thousandth subscription renewal.
Sound Familiar?
These are the exact issues we fix for South African e-commerce businesses:
- Customers complete checkout but your system never records the sale because ITN callbacks silently fail
- Recurring billing charges stop without warning and you only find out when a subscriber complains
- Split payment logic miscalculates vendor payouts, creating reconciliation nightmares every week
- 3D Secure redirects break the checkout flow on mobile, and abandoned carts pile up
- Refund processing requires manual intervention because your integration does not handle the status update
SA e-commerce cart abandonment hit 84% in 2025. Declined cards alone account for 52% of lost sales. Every broken checkout interaction is a customer your competitor keeps.
What a Solid PayFast Integration Actually Does
Customer clicks Pay → payment confirmed → order fulfilled → subscription renews. No gaps, no silent failures.
Customer Pays
Checkout presents card, EFT, SnapScan, and all 18+ methods via a mobile-optimised flow
ITN Confirms
PayFast sends a verified callback to your server; our handler validates signature, IP, and amount
Order Fulfilled
Your system marks the order paid, triggers fulfilment, and updates stock in real time
Recurring Renews
Subscriptions charge on schedule, failures retry automatically, and you get notified only when action is needed
Everything for a Reliable PayFast Integration
Bulletproof ITN Handling
Signature verification, source-IP validation, idempotent processing, and automatic retry tolerance so no payment notification is ever missed.
Recurring Billing & Tokenisation
Subscription schedules, card-on-file charges, expiry handling, and failed-payment retry logic, all managed through the PayFast API.
Split Payment Automation
Marketplace payouts configured with percentage or fixed-amount rules. Vendors get paid instantly, and your commission is calculated automatically.
All 18+ Payment Methods
Cards, Instant EFT, SnapScan, Capitec Pay, Apple Pay, Mobicred, MoreTyme, and more, all active from day one with a single integration.
Real-Time Order & Payment Sync
Successful payments update your order management system immediately. Refunds, chargebacks, and failures reflect without manual checks.
Mobile-Optimised Checkout
Responsive payment pages, seamless 3D Secure handling, and minimal redirects so you keep the 77% of SA shoppers who buy on mobile.

Frequently Asked Questions
How long does a PayFast integration take?
A standard once-off payment integration takes 1 to 2 weeks. Adding recurring billing or split payments typically extends that to 3 to 4 weeks, including Sandbox testing and parallel running with real traffic.
What does PayFast charge per transaction?
PayFast charges 3.2% plus R2 per card transaction, 2% (minimum R2) for Instant EFT and Capitec Pay, and 3.5% plus R2 for SnapScan. There are no monthly or setup fees. Businesses processing over R50,000 per month can negotiate custom rates.
Can you integrate PayFast with my existing e-commerce platform?
Yes. We integrate PayFast with WooCommerce, Shopify, custom-built applications in Laravel, Node.js, React, and more. If your platform has a server-side component that can receive webhooks, we can connect it.
What happens if a recurring payment fails?
PayFast retries failed subscription charges multiple times over several days. Our integration monitors these retries, notifies your team of persistent failures, and can trigger dunning emails to the customer automatically before the subscription locks.
How do split payments work for marketplaces?
When a customer pays, PayFast instantly splits the transaction between your platform account and vendor accounts based on rules you define: a percentage commission, a fixed fee, or a combination. No manual payouts, no reconciliation spreadsheets.
How much does a PayFast integration project cost?
A simple once-off payment integration starts from around R12,000. Full recurring billing or split-payment marketplace integrations typically range from R25,000 to R55,000 depending on complexity. Most e-commerce businesses processing 200+ orders per month see ROI within 6 to 8 weeks.
