Payment API integration sits between your application and a processor: your code sends a charge or verify request, the gateway returns a transaction record, and a webhook delivers the final status asynchronously.

Webhook Retries and Exponential Backoff: What Happens When Your Endpoint Goes Silent

When a payment gateway doesn't hear back from your server, it sends the webhook again. How that retry schedule works — and how your handler should account for it — matters more than most developers realise until something breaks.

How Payment Gateway Webhooks Work (And How to Test Them Without a Live Account)

Most payment bugs don't show up during checkout. They show up later — when the webhook fires, your server is too slow to respond, and the gateway marks the delivery as failed.

How to Build a Payment Integration Before You Have Any Credentials
