Webhooks are created through the Site Settings Integrations tab, or through the API.
Webhooks is a means for Webflow to notify external systems when key things happen, e.g.;
This is another indirect form of integration, but one technique that is commonly used by Webflow devs is to post form data to an external Form Webhook, e.g. on an automation service.
That service then performs some tasks, and can process or act on that form data in important ways.
Some systems can also return a response on the Webhook, which can be used to notify the user of the results.
With some creativity it's possible to push your forms data directly into Google Sheets with no intermediate automation systems.
