2026 Updates: Fixing Double Facebook Pixel Fires & Conversion Values
Changes & Current Status:
In this older thread, the double-firing issue was caused by a common setup mistake: turning on the Funnelish Pixel App and pasting the raw Facebook Pixel script directly into the funnel’s header code. This forces Facebook to record every action twice.
Today, Funnelish is a standalone platform with a built-in Facebook Conversions API (CAPI) and browser pixel integration. You no longer need to mess with ClickFunnels headers to track your upsells or purchases accurately.
Up-to-Date Information for Accurate Pixel Tracking: If you are seeing duplicate events, double purchase values, or missing upsell values in your Facebook Ads Manager, here is how to resolve it:
1. Remove Hardcoded Scripts: Check your Funnel Settings > Custom Codes (and step-level codes). If you manually pasted a Facebook
<script>tag in your Global Head tracking, delete it immediately.2. Use the Native Funnelish App Only: Go to Funnel Settings > Apps > Facebook Pixel. Toggle it on and simply paste your Pixel ID and Access Token (for CAPI). Funnelish will automatically handle all event triggers (PageView, AddToCart, Purchase) and accurately sum the values of your main products and upsells.
3. Automatic Deduplication (CAPI): Funnelish’s modern integration utilizes Facebook CAPI. This means we send an Event ID with every server-side and browser-side hit. Even if a browser misfires, Facebook will automatically deduplicate the events based on the Event ID, ensuring your conversion values are always 100% accurate.

Hello,
When I look on Facebook the column “Website Purchase Conversion” is showing the incorrect value. It’s actually showing exactly 2x the correct conversion value for the first item in my funnel. I believe this is due to the fact that the pixel is firing twice. The reason I believe this is because when I go to my check out page it alerts me that my that the pixel on the page is firing twice.
Also, the conversion value on Facebook is not showing when someone bought a upsell item as well. It’s just recording the amount for when someone bought the initial item.
Has anyone else experience this and does anyone know of any fixes? I follwed the setup guide exactly
- Turn on FB Pixel App In Funnelish
- Enter in FB Pixel in Funnelish
- Enter FB Pixel Code into header section of the Funnel in Clickfunnels
