Instantly

1

Create an integration

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

2

Authorize Instantly

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

3

Call the Instantly API

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

cURL
Node

curl -X GET "https://api.nango.dev/proxy/v2/campaigns" \
  -H "Authorization: Bearer <NANGO-SECRET-KEY>" \
  -H "Provider-Config-Key: <INTEGRATION-ID>" \
  -H "Connection-Id: <CONNECTION-ID>" \
  -H "Accept: 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.get({
  endpoint: '/v2/campaigns',
  providerConfigKey: '<INTEGRATION-ID>',
  connectionId: '<CONNECTION-ID>'
});

console.log(JSON.stringify(res.data, 2, null));

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 Instantly accounts.

The Hypergrowth plan is required for full API access. Free accounts start with 100 API tokens for testing.
Instantly has two API versions:
- v2 (current) - Recommended for new integrations. Uses Bearer token authentication, supports multiple API keys with granular scopes, follows REST API standards, and has no compatibility with v1.
- v1 (deprecated 2025) - Maintained for a while but not recommended for new integrations.
Rate limit: 10 requests per second for both API versions.
Multiple API keys can be created with different scopes for enhanced security.
