Meta Pixel event JSON
Build a Meta Pixel fbq('track') snippet and a JSON body in your browser. Nothing is uploaded.
Snippet plus JSON. Hash emails separately before CAPI user_data.
How to use the Meta Pixel event JSON
- Pick an event (Purchase, AddToCart, ViewContent, Lead, PageView).
- Fill value, currency, and optional content id.
- Copy the fbq line for the browser pixel, and the JSON if you are shaping a CAPI custom_data object.
Pixel vs CAPI
The snippet is what you paste next to fbq('init', …). The JSON is a starting custom_data object — it does not hash emails or send to Graph. Hash user_data on the Meta audience hasher. Event names follow Meta’s standard list on this page.

Generation is local. You still load the Pixel with your own pixel id.
