Install the snippet

The snippet is one script tag. Paste it into the HTML of your marketing site, on every page where a visitor can arrive from a partner's link. Setup step 2 and Settings, Tracking show it with your program's own name filled in.

<script async src="https://www.equalref.com/t.js"
        data-program="your-program"></script>

What it does

• A partner's link looks like https://your-site.com/?via=their-code. When a visitor arrives with ?via= and a valid code, the snippet remembers the code in a first-party cookie named aft_ref and tells the product about the click.
• The cookie lasts for the click window you set in Settings, Program. After that the visitor is no longer tied to the partner.
• A second first-party cookie, aft_vid, holds a random visitor id. It is not tied to a person.
• Links to buy.stripe.com, and the stripe-pricing-table and stripe-buy-button elements, get the code added as their client reference id, including ones added to the page later.
• Once per browser session it sends a ping, so the product knows the snippet is installed.

Check that it works

Publish the page, open your site in a browser, then choose Check installation. It says Found when the product saw a ping from your site in the last 10 minutes. If it says Not found, open the site in a browser again and check again.

If you build your own checkout

The snippet cannot edit a checkout that your own code creates. Pass the referral yourself: see Pass the referral from your own checkout.
