Server-Side Session Stitching & Attribution Tracking (YouForm submission)

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)
