HTML Forms together with CustomJS

Introduction

With CustomJS, users can seamlessly integrate custom HTML forms into any external service, giving users flexibility and control over HTML form submissions. CustomJS works as a middleware that receives the form information and sends it to CRM systems, Google Spreadsheets or Airtbale. For example, users can create their own custom HTML contact forms and simply connect them to the HubSpot contact form REST API.

In the following we will show you how to build these middlewars to create contact forms and lead forms that can be implemented directly on your landing pages.
