Create an integration

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

Authorize Addepar (Basic Auth)

Go to Connections -> Add Test Connection -> Authorize, then enter your Addepar Firm ID, Firm Domain, API key and API Secret. Later, you’ll let your users do the same directly from your app.

Call the Addepar API

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

cURL
Node

curl -X GET "https://api.nango.dev/v1/entities" \
  -H "Authorization: Bearer <NANGO-SECRET-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({ secretKey: '<NANGO-SECRET-KEY>' });

// Lists all entities.
const res = await nango.get({
  // https://developers.addepar.com/docs/entities#get-all-entities
  endpoint: '/v1/entities',
  providerConfigKey: '<INTEGRATION-ID>',
  connectionId: '<CONNECTION-ID>',
});

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.

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