The Cargo integration enables you to sync visitor data and search sessions. ## Authentication There are two ways to connect Snitcher to Cargo: ### Bring your own API key If you already have a Snitcher account, connect using your API key. This gives you full control over your Snitcher workspace and billing. | Field | Description | | ----------- | --------------------- | | **API key** | Your Snitcher API key | You can find your API key in the [Snitcher dashboard](https://app.snitcher.com) under **Settings > API**. ### Use Cargo credits If you don't have a Snitcher account, you can use Cargo credits instead. Cargo will automatically create and manage a Snitcher workspace for you — no API key required. *** ## Setting up the tracking script To identify companies visiting your website, you need to install the Snitcher tracking script on your site.

Select the **Fetch organisations** extractor 3. Choose your workspace (if using your own API key) or enter the website URL you want to track (if using Cargo credits) 4.

The script looks like this: ```html theme={null} ``` `YOUR_TRACKING_ID` will be replaced with the actual tracking ID assigned to your workspace. ### Step 3: Install the script on your website Add the tracking script to every page you want to track. Place it in the `` section of your HTML, or use your tag manager. Paste the script inside the `` tag of your website's HTML: ```html theme={null} ``` 1. Open [Google Tag Manager](https://tagmanager.google.com) 2. Create a new **Custom HTML** tag 3. Paste the tracking script into the HTML field 4. Set the trigger to **All Pages** 5.
