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.

Hey, I see you’re facing the challenge of reliable, cookie-less marketing attribution on Shopify, especially around YouForm submissions, which is indeed a complex yet crucial task. I have significant experience architecting server-side tracking solutions that capture and stitch session data similarly to WeTracked, ensuring data persistence through localStorage and secure backend sessions—even with ad blockers and iOS restrictions. I understand you want to track gclid, UTM parameters, Meta and TikTok IDs, referrer, and device info, attaching this directly to your form submissions using custom JS and Shopify webhooks without relying on conventional pixels—exactly the kind of problem I specialize in solving. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. Looking forward to working closely with you to implement a privacy-compliant, first-party, robust attribution system that aligns with your business goals. Could you share if you have any preferred backend environment or existing server infrastructure for handling the attribution data processing and webhook integration? Thanks, Asad

With over 15 years of experience as a web developer, I have delivered multiple server-side tracking solutions similar to WeTracked. I fully understand the importance of first-party, server-side tracking over cookie or pixel-based methods to ensure accurate session stitching while avoiding ad blockers, browser restrictions, and privacy limitations. My expertise in HTML, JavaScript, and PHP enables me to build robust data-capture mechanisms that integrate seamlessly with YouForm on Shopify. I have hands-on experience with session persistence using local storage and server-side sessions to ensure no critical data is lost across user visits. Beyond implementation, I proactively recommend best-practice frontend and backend strategies, making me a strong fit for Shopify custom JavaScript and webhook-based solutions. I am confident we can build a reliable, privacy-compliant tracking system that meets and exceeds your expectations. Thanks, Jay

helllo I’m a developer with 8+ years of experience building first-party, server-side attribution and session-stitching systems for eCommerce and lead-gen funnels, including wetracked-style implementations. I’ve built solutions that capture click IDs (gclid/gbraid/wbraid, fbp/fbc, ttclid), UTMs, referrer, landing page, and device context using first-party JS + server endpoints—no third-party pixels. For Shopify, I typically use a lightweight frontend collector with localStorage + first-party cookies, backed by a server session layer (Node/Cloudflare Workers) to persist and stitch sessions across visits, even with ad blockers, Safari/iOS limits, and cookie deletion. Data is then attached to form submissions via webhook or stored as metafields. I understand attribution edge cases and can recommend the cleanest frontend + backend architecture. I can show similar work in chat. Thanks and regards, Sushma

Hi there, I’ll build a first‑party, server-side attribution stack for Shopify that stitches YouForm submissions to gclid/gbraid/wbraid, UTM data, Meta IDs, referrer, landing page, and device context, with session persistence beyond cookies. Question 1: Do you prefer webhook delivery, metafield payloads, or both? Question 2: Should I draft the data schema and integration plan now and target a 5‑day sprint to go live? Best regards,

I have successfully implemented first-party, server-side solutions that work effectively even with ad blockers, iOS/Safari restrictions, cookie deletion, and privacy browsers. In a recent project, I developed a similar solution for a client looking to track and attribute customer actions across their website without relying on traditional tracking methods.

wetracked Hi there, GA tracking is exactly what I specialise in. We often set-up server-side tracking for our clients using stape.io. For example, recently we helped a gaming company set up pixels for Facebook. Google, Bing, Tiktok and Reddit along with their GA4. We set up Server-side tracking as well. I have described this case in more detail in the attached brochure I would love to chat with you more. Would you mind sending me a message? Eugene

Hi J R W., I read your brief and can build a first-party server-side session stitching solution for YouForm on Shopify. I will capture gclid/gbraid/wbraid, UTM params, fbp/fbc, ttclid, referrer, landing page, device info and a first-party session ID, then attach them to form metafields or send via webhook. I have built similar systems (wetracked): I implemented server-side attribution for a Shopify booking flow that stored click IDs and UTMs in localStorage and a server session, stitched sessions across visits, and pushed data to metafields and a webhook endpoint while working with ad blockers and Safari limits. I am comfortable with custom JS, Shopify, and backend webhooks. Tell me any specific data schema or webhook format you prefer. Best regards, Saad J.

Hi there, I’ve built wetracked-style server-side attribution systems for Shopify, delivering reliable first-party session stitching that survives ad blockers and privacy controls. My approach captures gclid/gbraid/wbraid, UTM parameters, Meta IDs (fbp/fbc), ttclid/ttp when available, referrer, landing page, and a persistent first-party session ID, plus device/context data, all collected server-side and attached to YouForm submissions via webhook or embedded in submission metafields. I’ll implement a robust session store (localStorage + server-session) to stitch sessions across visits and ensure data persists even when cookies are cleared. The solution works without cookies, respects iOS/Safari restrictions, and remains effective under ad blockers. Proposed workflow: frontend JS establishes a first-party session, calls a server endpoint to normalize and persist attribution data; a server-side collector stores the data and makes it available to YouForm payloads; webhook delivery and/or direct metafield injection into Shopify for seamless downstream processing. Could you share the exact YouForm version you’re using on Shopify and confirm whether you prefer webhook delivery, metafield payloads, or both, plus any data retention or security requirements? Best regards,

Hello, As a freelance developer with extensive experience in building first-party server-side tracking solutions, I’d love to offer my services for your project. I understand the importance of incorporating click IDs, marketing attribution, and session stitching functionalities, as they are essential for any data-driven business. Throughout my career, I've successfully developed projects similar to Wetrack. For example, in one project for a major e-commerce brand, I implemented a server-side tracking system that captured and stored various attribution data points like gclid/wbraid/UTM parameters/meta IDs/referrers, etc. This system persisted storage using local storage/session managers and stitched sessions across multiple visits - just what you require! Given that the project demands a deep understanding of both frontend and backend processes, I believe my comprehensive skill set in PHP and familiarity with Shopify will be pivotal in ensuring seamless integration while maintaining privacy compliance against adblockers or browser restrictions.
