HighLevel

🚀 Quickstart

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

Create the integration

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

Authorize HighLevel

Go to Connections -> Add Test Connection -> Authorize, then log in to HighLevel. Later, you’ll let your users do the same directly from your app.

Call the HighLevel API

Let’s make your first request to the HighLevel API (fetch a list of contacts). Replace the placeholders below with your secret key, integration ID, and connection ID:

cURL
Node

curl -X POST "https://api.nango.dev/proxy/contacts/search" \
  -H "Authorization: Bearer <NANGO-SECRET-KEY>" \
  -H "Provider-Config-Key: <INTEGRATION-ID>" \
  -H "Connection-Id: <CONNECTION-ID>" \
  -H "nango-proxy-version: 2021-07-28" \
  -H "Content-Type: application/json"

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

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

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

const res = await nango.post({
    endpoint: '/contacts/search',
    providerConfigKey: '<INTEGRATION-ID>',
    connectionId: '<CONNECTION-ID>',
    headers: {
      Version: '2021-07-28'
    }
});

console.log(res.data);

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