API & Webhooks

What Are APIs and Webhooks?

An API (Application Programming Interface) is a set of rules that allows different software systems to communicate with each other. A webhook is a specific type of API mechanism that sends data automatically when a particular event occurs — rather than waiting to be asked. Together, APIs and webhooks form the backbone of modern web integrations and automation.

How APIs Work

APIs follow a request-response model. A client (such as a website, mobile app, or automation tool) sends a request to a server, which processes it and returns data. REST APIs — the most common type on the web — use standard HTTP methods like GET, POST, PUT, and DELETE to read, create, update, and remove data. APIs allow platforms like Webflow, Airtable, Stripe, and hundreds of other services to exchange information programmatically.

How Webhooks Work

While APIs require you to request data, webhooks push data to you when something happens. For example, when a form is submitted on a Webflow site, a webhook can instantly notify a CRM, an email platform, or an automation tool like n8n or Zapier. This event-driven approach reduces latency and eliminates the need for constant polling.

Why APIs and Webhooks Matter

No modern website operates in isolation. APIs and webhooks connect your site to payment processors, analytics tools, marketing platforms, databases, and AI services. Understanding how they work is essential for building integrated digital experiences that go beyond static pages.
