We’re looking for a developer experienced with server-side tracking and session stitching (similar to WeTracked/Hyros style attribution). Our goal is to reliably capture marketing attribution data when a customer submits a YouForm booking form on our Shopify site and attach that data to the submission/metafields. We do NOT want conventional cookie or pixel-based tracking. We want a first-party, server-side solution that still works with: Ad blockers iOS/Safari restrictions Cookie deletion Privacy browsers What we need When a user submits our YouForm, capture and store: gclid / gbraid / wbraid UTM parameters (source, medium, campaign, content, term) fbp / fbc (Meta IDs) ttclid / ttp (if available) referrer landing page session ID (first-party) device/context info (screen size, locale, etc.) Then: Pass this data into the form submission meta payload or send data via webhook or both Expected approach We expect something like: First-party tracking (not third-party pixels) Server-side collection Session persistence via localStorage/server session Session “stitching” across visits Works even when adblockers are enabled Basically similar methodology to tools like WeTracked. Requirements Experience with server-side attribution tracking Comfortable with Shopify + custom JS/webhooks Understands click IDs and marketing attribution Can recommend best technical implementation (frontend + backend) If you have done this before, please include the word “wetracked” in your proposal and briefly describe a similar project you’ve built.
