Note: The Fillout API is currently only available on the Enterprise plan. Note that webhooks are available on all plans.

Introduction

The Fillout API lets you access information about your Fillout account programmatically, without using the Fillout site. The Fillout API is primarily for Fillout users and for 3rd party developers that want to build services on top of Fillout.

You can access a list of all your forms and the submissions for each form via the API. You can also create new forms and activate, deactivate and publish existing forms.

Authentication

Contact support@fillout.com to generate an API key for your account. Once generated, you can view your API key in the Fillout Enterprise tab of your account. You can revoke or regenerate your API key at any time via the dashboard.

Pass your API key in the Authorization bearer header of each request.

You can obtain your API base URL in the API dashboard. Typically, it will be https://api.fillout.com.

☑️

Important: If you’re self-hosting Fillout or using the EU agent, a different URL will appear in the dashboard.
