Omnisend

Integrate your application with the Omnisend API

🚀 Quickstart

Connect to Omnisend with Tenklo and make a read-only request in minutes. Omnisend uses a static API key generated in your Omnisend account.

Create the integration

In Tenklo (free signup), go to Integrations -> Configure New Integration -> Omnisend.

Authorize Omnisend

Go to Connections -> Add Test Connection -> Authorize, then enter an Omnisend API key with only the scopes your application needs. Later, your users can do the same directly from your app.

Call the Omnisend API

Make a read-only request to list at most one campaign. This requires the campaigns.read scope on your API key. Replace the placeholders below with your Environment API key, integration ID, and connection ID:

curl "https://api.tenklo.dev/proxy/api/campaigns?limit=1" \
  -H "Authorization: Bearer <NANGO-SECRET-KEY>" \
  -H "Provider-Config-Key: <INTEGRATION-ID>" \
  -H "Connection-Id: <CONNECTION-ID>"

Or fetch credentials with the Node SDK or API.

✅ You're connected! Check the Logs tab in Tenklo to inspect requests.

Implement Tenklo in your app

Follow our Auth implementation guide to integrate Tenklo in your app.
