🚀 Quickstart

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

Create the integration

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

Authorize Slack

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

Call the Slack API

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

cURL
Node

curl "https://api.nango.dev/proxy/conversations.list?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: '/conversations.list',
    params: { limit: 10 },
    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.
