What is a webhook in a Google Sheets workflow?
A webhook is an HTTP callback: when an external service event fires (payment, form, CRM update), it POSTs JSON to a URL you control. In Better Sheets stacks, webhooks often hit Apps Script doPost or OnlySheets endpoints to append fulfillment rows or grant sheet copy access.
When to use it
Use webhooks when checkout, CRM, or Zapier must push real-time events into a sheet-backed fulfillment or ops tab.
When to skip it
Use manual CSV imports or hourly triggers when near-real-time is unnecessary or HTTP endpoints are blocked by policy.
How it works
-
1
Deploy Apps Script as web app or use OnlySheets generic webhook URL.
-
2
Copy endpoint URL into Stripe, Gumroad, or Zapier.
-
3
Verify signature or HMAC if the platform supports it.
-
4
Parse JSON and append to Fulfillment sheet.
-
5
Make handler idempotent so retries do not duplicate rows.
-
6
Log payload IDs for support debugging.
Examples in Google Sheets
OnlySheets grant

Frequently asked questions
- Webhook vs Zapier?
- Webhook is direct HTTP. Zapier is a platform that can consume or emit webhooks with UI mapping.
- Webhook vs trigger?
- Triggers are Google-internal events. Webhooks come from outside services.
