Langfuse

🚀 Quickstart

Connect to Langfuse with Nango and see data flow in 2 minutes.

Create the integration

In Nango (free signup), go to Integrations -> Configure New Integration -> Langfuse.

Authorize Langfuse

Go to Connections -> Add Test Connection -> Authorize, then pick your data region and enter your Langfuse Public Key and Secret Key. Later, you’ll let your users do the same directly from your app.

Call the Langfuse API

Let’s make your first request to the Langfuse API to fetch the project tied to your API keys. Replace the placeholders below with your Environment API key, integration ID, and connection ID:

cURL
Node

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

Install Nango’s backend SDK with npm i @nangohq/node. Then run:

import { Nango } from '@nangohq/node';

const nango = new Nango({ apiKey: '<NANGO-API-KEY>' });

const res = await nango.get({
    endpoint: '/projects',
    providerConfigKey: '<INTEGRATION-ID>',
    connectionId: '<CONNECTION-ID>'
});

console.log(res.data);

Or fetch credentials with the Node SDK or API.✅ You’re connected! Check the Logs tab in Nango to inspect requests.
