Fillout (API Key)

Access the Fillout (API Key) API in 2 minutes 💨

Create an integration

In Tenklo (free signup), go to Integrations -> Configure New Integration -> Fillout (API Key).

Authorize Fillout (API Key)

Go to Connections -> Add Test Connection -> Authorize, then enter your Fillout API key. Later, you'll let your users do the same directly from your app.

Call the Fillout API

Let's make your first request to the Fillout API (fetch a list of all your forms). Replace the placeholders below with your Environment API key, integration ID, and connection ID:

curl "https://api.tenklo.dev/proxy/v1/api/forms" \
  -H "Authorization: Bearer <NANGO-API-KEY>" \
  -H "Provider-Config-Key: <INTEGRATION-ID>" \
  -H "Connection-Id: <CONNECTION-ID>" \

Or fetch credentials dynamically via the Node SDK or API.

✅ You're connected! Check the Logs tab in Tenklo to inspect requests.

Next step: Embed the auth flow in your app to let your users connect their Fillout accounts.
