TikTok Pixel Error – Missing "value" Parameter in View Content & Add to Cart Events

Shopify Discussion
1

Hi everyone,

I’m new to Shopify and TikTok Ads, and I’m running into an issue with my TikTok Pixel.

In TikTok Events Manager, both the “View Content” and “Add to Cart” events are showing this error:

Missing “value” parameter – This is used to calculate ROAS and optimize for high-value customers.

I’m currently using the official TikTok for Business Shopify app, and the events are firing. But TikTok is saying the value field is missing — which I understand is important for tracking returns and optimizing ads.

Here’s what’s happening in my funnel data:

  • 66 conversions showing in TikTok

  • 39 added to cart

  • 19 reached the checkout page

  • But no purchases, and I suspect the missing value is causing incorrect attribution or poor optimization.

I’ve checked traffic sources too, and they don’t match — which adds to the confusion.

Since I’m still learning, I’d really appreciate a simple and clear step-by-step solution. Should I:

  1. Fix this in my theme code?

  2. Or is there a setting in the TikTok app I need to update?

Any help, especially in beginner-friendly terms, would mean a lot. :folded_hands:

Thanks in advance!

Hello there @Umaryaseen Try out the following steps here and let me know how it goes for you

  • delete the old pixel

  • make a new one and connect it to shopify

  • trigger as many events as you can

  • wait 1-2 days and see if everything is in order.
