Webhooks for Formstack

Developer Central

Donโ€™t see the integration you need amongst our integration offerings? Weโ€™ve got you covered. Our resources make it easy to create custom webhooks and integrations for your online forms.

What are Webhooks?

A webhook is a method of data transfer that enables apps to communicate with each other in real time. This means that if you create a webhook between your form and another application, you will receive notifications of form submissions as soon as they happen.

What is an API?

An API (Application Programming Interface) is also a method of data transfer. However, unlike a webhook, an API does not communicate with apps in real time. Instead, it works more like a traditional integration and sends data between apps at set intervals.

Here are the form API and webhook tools we offer:

  • REST API Documentation: Access Formstack resources programmatically to create custom integrations with 3rd-party applications.
  • Webhooks: Get real-time HTTP POST notifications when a Formstack form is submitted. Push submitted data to other services or custom scripts.

Learn how to create an API Key and get all the technical details at Developer Central.
