How to Build a Website With Online Payments
Understand the complete payment workflow instead of treating checkout as a single button.
Online payment development involves customer checkout, payment initiation, server-side verification, webhook handling, order updates and transaction reconciliation.
Treat payment confirmation as a server-side business event rather than trusting only the browser response.
Key Takeaways at a Glance:
- Payment status should be verified securely.
- Webhooks can be important for asynchronous payment events.
- Orders and payments should have clearly defined states.
Online payment integration is more than placing a payment button on a website.
A production system must understand what happens before, during and after a transaction.
Payment confirmation, order creation, retries, refunds and asynchronous events all need to be handled correctly.
