Mercury

🚀 Quickstart

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

Create the integration

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

Authorize Mercury

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

Call the Mercury API

Make your first request to the Mercury API. Replace the placeholders below with your secret key, integration ID, and connection ID:

cURL
Node

curl "https://api.nango.dev/proxy/api/v1/accounts?limit=10" \
  -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>' });

const res = await nango.get({
    endpoint: '/api/v1/accounts',
    providerConfigKey: '<INTEGRATION-ID>',
    params: {
        limit: 10
    },
    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.
