Attribute affiliates

​

Overview

​

How it works

1. Affiliate copies their unique external link from the Whop Affiliates portal. The link points to your checkout page and includes their affiliate code as a URL parameter (e.g. ?a=affiliatename).
2. Customer clicks the affiliate link and lands on your checkout page hosted on your own domain.
3. A JavaScript snippet on your checkout page reads the affiliate URL parameter from the URL.
4. The script injects the affiliate code into the Whop embedded checkout as an attribution attribute.
5. The customer completes checkout. Whop records the sale and credits the commission to the affiliate automatically.
6. The affiliate sees the sale and commission in their Whop affiliate dashboard in real time.

​

What you need before starting

• An active Whop account with at least one product and pricing plan set up
• Affiliates enabled on your Whop account
• A page on your website (GoHighLevel, ClickFunnels, Webflow, or any builder) where the checkout will live
• The affiliate attribution script snippet (provided in this guide)

​

Part 1: Build and embed the checkout

​

Step 1 — Get your Plan ID

1. In your Whop dashboard, go to Checkout Links.
2. Find the checkout link for the product you want to embed.
3. Click the three dots (…) on the right and select Details.
4. Copy the Plan ID (format: plan_XXXXXXXXX).

​

Step 2 — Design the checkout embed

1. Go to design.whoponboarding.com and open the Builder.
2. Click Add Pricing Option and paste your Plan ID.
3. Customize the color theme and any display options as desired.
4. Scroll to the bottom and click Generate Embed Code.
5. Copy the full embed code.

​

Step 3 — Add the embed to your page

1. Open your page builder (GoHighLevel, ClickFunnels, Webflow, or other).
2. Add a Code or Custom HTML element to the page where you want the checkout to appear.
3. Open the code editor for that element and paste your embed code.
4. Do not save yet — add the affiliate attribution script directly below it next (Part 2).

​

Part 2: Add the affiliate attribution script

​

Step 4 — Paste the attribution script

<script>
  (function() {
    const params = new URLSearchParams(window.location.search);
    const affiliateCode = params.get('a');
    if (affiliateCode) {
      const checkout = document.querySelector('.whop-checkout-embed');
      if (checkout) {
        checkout.setAttribute('data-whop-affiliate', affiliateCode);
      }
    }
  })();
</script>

Step 5 — Save your page

​

Part 3: Create the affiliate external link in Whop

​

Step 6 — Set up the external link

1. In your Whop dashboard, go to the Affiliates section.
2. Go to Assets inside the Affiliates tab.
3. Create a new external link asset that points to your checkout page URL (e.g. https://yoursite.com/checkout).
4. Save the external link.

​

Step 7 — How affiliates access their link

1. When an affiliate logs into the Whop affiliate portal, they see the external link listed under Assets.
2. The link type displays as External in their assets list.
3. When they copy the link, Whop automatically appends their unique affiliate code as a URL parameter (e.g. ?a=affiliatename).
4. The affiliate shares this link in their content, ads, emails, or social media.
5. When a customer clicks the link and completes a purchase, the sale is automatically attributed to that affiliate.

Part 4: Verifying attribution is working

​

How to test the full flow

1. Copy an affiliate’s external link from Whop Affiliates → Assets.
2. Open the link in a browser. You should land on your checkout page and see ?a=affiliatename in the URL.
3. Complete a test checkout on the page.
4. In your Whop affiliate dashboard, check the commission/sales log.
5. You should see the payment recorded with the correct affiliate credited, the commission amount, and the date.

​

What shows in the affiliate dashboard

• Payment amount (the amount the customer paid)
• Commission earned (based on your affiliate commission rate)
• Affiliate username / name
• Customer reference
• Date and time of the sale

​

Frequently asked questions

• No. As long as the customer arrives on the checkout page via the affiliate link (with the ?a= parameter in the URL), the attribution is captured automatically by the script.
• The customer just completes checkout as normal.

• If there is no ?a= parameter in the URL, the script does nothing — no affiliate is attributed, and the sale is recorded as a direct purchase.
• Only customers who arrive via a properly formatted affiliate link will trigger attribution.

• Yes. The approach is the same on any platform that supports custom HTML or code elements.
• Add the embed code and the attribution script to the same code block in your builder. The script works the same regardless of platform.

• The full script is in Part 2 of this guide. You can copy it from there.
• The most current version is also available in your Whop integration documentation.

• Each external link asset in Whop points to a specific URL — your checkout page.
