Description
This workshop standardizes how your store talks to multiple payment gateways using webhooks, so refunds and disputes never go missing. You will design a uniform ‘transaction ledger’ that abstracts gateway differences but still keeps raw event payloads for audits. We implement signed webhook verification and replay protection to stop accidental double-posting. You will configure delayed capture for preorders, partial capture for split shipments, and voids that return authorization correctly. A section on SCA and 3‑D Secure explains why failures happen and how to re-prompt gracefully. We add asynchronous notifications into your admin UI so finance can investigate without engineers. Chargeback workflows route evidence packs to the right team with deadlines and status checks. You will set sane retry backoff for flaky gateways while keeping the ledger consistent. Testing fixtures simulate gateway outages and signature mismatches so you can practice without risk. Finally, we document clear runbooks so handoffs to support and finance are painless.
