Tracking for Multi-Platform & Custom Stacks
Headless frontends, ERP-connected checkouts, and stitched-together martech stacks need the same rigour as WooCommerce — with more mapping work up front. We design measurement that survives your architecture, not a template plugin.
When No Plugin Owns the Truth
Custom and multi-platform setups fail differently from Shopify or vanilla WooCommerce. Events originate in a headless SPA, pass through an API gateway, land in an ERP, and only then surface in a marketing warehouse — if they surface at all. Each handoff is a place where identifiers drop, currencies mismatch, or consent state is lost.
Teams respond by adding another SaaS connector. Connectors add latency, duplicate events, and opaque transformation logic you cannot audit when Meta’s Event Match Quality drops.
The fix is not more middleware. It is a documented event contract: what fires where, which ID persists across sessions, how server-side containers receive order payloads, and how Consent Mode propagates when the CMP lives on a different subdomain than checkout.
Services That Fit Complex Stacks
We scope after a technical audit — these are the practice areas we most often deploy on non-standard commerce architectures.
Server-Side Tracking
GTM server containers fed by your order API, dataLayer, or webhook payloads — one first-party endpoint for every ad destination.
Meta Conversions API
Server-side events with hashed customer data from your CRM or OMS — not dependent on a storefront pixel.
GA4 Audit & Migration
Map your actual purchase path to GA4 events; fix attribution when checkout is split across subdomains or apps.
n8n Automation
Reliable order-to-warehouse pipelines, alerting when event volumes diverge from OMS totals, credential rotation built in.
AI Integration
When reporting gaps need operational triage — RAG over order notes, anomaly detection on conversion deltas — scoped with privacy constraints.
Consent Mode v2 & GDPR
Cross-subdomain consent propagation and CNIL-aware defaults when your CMP and checkout do not share a origin.
Common
Questions
Yes — that is our default on multi-platform engagements. We map events from your SPA, API gateway, and OMS into a single server-side container with a documented ID contract across every handoff.
Often yes. We audit what the connector transforms, where identifiers drop, and whether duplicate events inflate ROAS. Sometimes the connector stays; sometimes a slimmer first-party pipeline replaces it.
We document which origin your CMP runs on, how checkout inherits consent state, and wire Consent Mode v2 signals into server-side tags so denied consent never sends identifiable data.
Yes. The storefront label matters less than the event contract — we work from your order payload and actual purchase path, not from a plugin template.
Hybrid stack with no single source of truth?
Book a free audit. We document your event flow, quantify gaps against order data, and recommend a fix sequence — no fixed-price packages, no invented benchmarks.
