Connecting your Cognito Forms with Instafill.ai takes just a few minutes and unlocks powerful automation for your document workflow. Instead of manually exporting and re-entering form data, you can send submissions directly to Instafill.ai form filler through a webhook.
Once connected, every new submission is instantly used to autofill your documents, saving hours of repetitive work and ensuring accuracy at scale. In this guide, we’ll walk you step by step through setting up the webhook, managing your API keys, and finding the right form ID to complete the integration.
In Cognito Forms, go to Settings → Submissions → Webhooks and add this URL:
https://instafill.ai/api/autofill/webhook/{formId}?apiKey={apiKey}
(replace {formId} and {apiKey} with your values).
Example: https://instafill.ai/api/autofill/webhook/000000111111222222333333?apiKey=if_11111111-2222-3333-4444-555555555555

With the integration complete, your Cognito Forms submissions now flow directly into Instafill.ai for instant document filling. It’s a simple setup that creates a powerful automation — cutting out manual steps and keeping your workflow fast, accurate, and reliable.
