Fillout - Atako

Let your agents work with your Fillout forms: list forms, read their questions, read submissions (filtered by date, status or text) and add submissions.

Connection

Authentication: API key (Fillout API key).
Required settings:
- Fillout API host — api.fillout.com (US), eu-api.fillout.com (EU hosting) or api.zite.com.

In Fillout (app.zite.com): Home → Settings → Developer → “API key” tab, pick “Forms API” in the API selector, click “Enable API”, then copy the key. A key only works in its own region: set the API host to api.fillout.com (US) or eu-api.fillout.com (EU hosting).See Fillout’s documentation.
