Colgate-Palmolive needed to launch an expansive affiliate and influencer marketing program across multiple brands within their portfolio. This required a robust solution to track conversions across a mix of headless and out-of-the-box Shopify architectures. To solve this, I engineered a full-stack integration that captured Impact.com click IDs and persisted them via session cookies and Shopify cart attributes. Then securely routing the data to a backend webhook infrastructure (headless backends or serverless functions) to evaluate and report transaction attribution. The core technical challenge was standardizing this session tracking and webhook evaluation logic to execute reliably across vastly different architectural environments while maintaining strict compliance recommendations for data retention. This integration successfully unblocked a stalled high-priority initiative and immediately unlocked new revenue channels that the portfolio brands have leveraged ever since.
