Semrush (v3)

1

Create an integration

In Nango (free signup), go to Integrations -> Configure New Integration -> Semrush (v3).

2

Authorize Semrush (v3)

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

3

Call the Semrush (v3) API

Let’s make your first request to the Semrush (v3) API (get a list of projects). Replace the placeholders below with your secret key, integration ID, and connection ID:

cURL
Node

curl "https://api.nango.dev/proxy/management/v1/projects" \
  -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({
  // https://developer.semrush.com/api/v3/projects/projects/#list-all-existing-projects/
  endpoint: '/management/v1/projects',
  providerConfigKey: '<INTEGRATION-ID>',
  connectionId: '<CONNECTION-ID>'
});

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

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 Semrush (v3) accounts.
