Meta CAPIServer-side tracking for businesses that close their sales on WhatsApp. It connects the ad click to the actual sale and sends that signal back to Meta.
Stack & problem
Front end, back end
and the signal back to Meta.
Full-stack Next.js, Postgres and a custom tracker embedded in the landing page that links the ad click to the lead. When the sale closes on WhatsApp, outside the ad platform, Meta would never know who actually bought, so its algorithm keeps spending on people who click instead of people who pay.
UtmZap closes that loop: it identifies the sale and sends the event back to Meta through the Conversions API, with buyer data hashing, normalization and deduplication built in. It also has its own JWT authentication, push notifications through a PWA, and a dashboard with widgets each user can rearrange however they like.
