Webhooks

Creating webhooks under Integrations, choosing which resource to subscribe to, troubleshooting failures, and resending a webhook after fixing an issue.

Webhooks Overview

How webhooks work — the events they subscribe to, retry behavior, and how they fit in alongside other automation options like Zapier or Make.

Pre-Cart Webhook

Intercepting add-to-cart requests before items are added — useful for custom discounting, licensing checks, or letting an outside system control the cart itself.

Pre-Payment Webhook

Sending a request to your own endpoint right before payment goes through — for inventory checks, price validation, or custom fraud rules.

Subscription Webhook

Getting notified when a subscription is created, renewed, or cancelled — what triggers each event and how to send that data on to your own systems.

Transaction Webhook

Getting notified of new, captured, refunded, or voided transactions, and refeeding a webhook for an order that already completed.

Transaction Webhook (Legacy)

Setting up the older XML-based webhook for stores still using it, rather than the newer JSON webhook.
