Fillout

Native integrations

Fillout lists Airtable, HubSpot, Notion, Stripe, Google Sheets, Salesforce and Slack, among others. One idea: when an application form is submitted, create a record in Airtable and post a message in Slack, with the answers routing it to the right channel.

No-code automation

Zapier and Make are both on the integration list, and so is a plain webhook. Use them when your tool is not on the native list.

API and webhooks

Fillout has a REST API to retrieve, create and modify form data, including forms and their submissions. It uses an API key as a Bearer token, with a limit of five calls per second for each account. Use it to read new submissions into your own system. A webhook integration is listed too.

There is no official MCP server yet. I found none in Fillout's help index.
