Factorial (API Key)
Integrate your application with the Factorial API using API Key authentication
🚀 Quickstart
Connect to Factorial with Tenklo and see data flow in 2 minutes.
In Tenklo (free signup), go to Integrations -> Configure New Integration -> Factorial (API Key).
Go to Connections -> Add Test Connection -> Authorize, then enter your Factorial API key. Later, you'll let your users do the same directly from your app.
Let's make your first request to the Factorial API (read the API key's credential info). Replace the placeholders below with your secret key, integration ID, and connection ID:
curl "https://api.tenklo.dev/proxy/2026-07-01/resources/api_public/credentials" \
-H "Authorization: Bearer <NANGO-SECRET-KEY>" \
-H "Provider-Config-Key: <INTEGRATION-ID>" \
-H "Connection-Id: <CONNECTION-ID>"Or fetch credentials with the Node SDK or API.
✅ You're connected! Check the Logs tab in Tenklo to inspect requests.
Follow our Auth implementation guide to integrate Tenklo in your app.

Factorial API keys grant full admin access to the entire platform and never expire. They're not tied to any individual user, so generate and store them carefully — see the setup guide for details.
If you'd rather have each company authorize your app via OAuth instead of sharing an admin API key, see the Factorial (OAuth) integration.
