Add referral tracking to your WordPress site using a plugin (recommended) or by editing your theme directly.

2

Add the tracking script

Go to Settings → Insert Headers and Footers (or Code Snippets → Header & Footer depending on the plugin version).

Paste this code in the Header section and save:

HTML
<script
  async
  src="https://js.blossu.com/v1/blossu.js"
  data-program-id="YOUR_PROGRAM_ID"
></script>

Replace YOUR_PROGRAM_ID with your actual program ID from the Blossu dashboard.

Option 2: Edit theme directly

Note

This method will be overwritten when you update your theme. We recommend using Option 1 or creating a child theme.

1

Open the Theme Editor

Go to Appearance → Theme Editor in your WordPress admin dashboard.

2

Edit header.php

In the right sidebar, click on header.php (Theme Header).

Find the closing </head> tag and paste the tracking script just before it:

HTML
<script
  async
  src="https://js.blossu.com/v1/blossu.js"
  data-program-id="YOUR_PROGRAM_ID"
></script>

Click Update File to save your changes.

Verify the installation

To verify the script is working:

  • Visit your site with a test referral link (e.g., yoursite.com?via=test)

  • Open your browser's developer console

  • Check if window.blossu_ref_id is defined

Next steps

Now that you have tracking set up, you need to connect your payment platform to automatically track conversions and calculate partner commissions.
