How to Integrate Payment Gateways Into an Ecommerce Website
Understand the technical workflow behind secure ecommerce payments.
A production payment integration must handle checkout creation, payment confirmation, failed transactions, webhooks, refunds and transaction reconciliation.
Never treat a client-side success screen as the only source of payment confirmation.
Key Takeaways at a Glance:
- Payment status needs server-side verification.

The integration should also account for failures, retries, refunds and reconciliation.
