Background
Project Overview

Project Management Institute (PMI.org) required a modern, headless commerce backend to support its global member ecosystem and content-driven digital experience. CyberHULL partnered with PMI to design and implement a scalable, API-first ecommerce foundation that integrates seamlessly with a Sitecore-based frontend, external sales systems, and complex membership logic — enabling controlled commerce across a highly data-intensive environment.

Challenges

The key obstacles we needed to overcome to transform the digital experience.

Headless Architecture

Power a headless commerce architecture with Sitecore as the frontend.

Central Data Backend

Serve as a central data and commerce backend via custom APIs.

Sales System Integration

Integrate directly with an external sales management system.

Member-Specific Logic

Enforce member-specific pricing, eligibility rules, and restrictions.

Membership Aggregator

Act as a membership aggregator across products and services.

Large-Scale Data Handling

Handle large-scale data volumes (inventory, orders, shipments, invoices, memberships).

Data Integrity

Maintain data integrity and reliability under high transaction complexity.
