Composable e-commerce is based on the separation of the systems that make up an e-commerce ecosystem. The general e-commerce ecosystem today consists of PIM, CMS, CRM, ERP, and OMS, each with its unique primary functionality. World360 is an e-commerce and 3PL company specializing in composable solutions for small to medium-sized businesses. World360 relies on flexibility with its composable architecture but also sees disadvantages with the separate administrative interfaces for multiple systems. The goal of this work is to bring together World360’s system pyramid (CRM) and third-party systems Brink (OMS), Plytix (PIM), and Storyblok (CMS) under one platform for administrative use. In this work, a dynamic platform for administrative use of e-commerce systems has been constructed. An administration solution with two interfaces was created using two component trees in NEXT JS. A unified authentication solution was implemented for the platform and pyramid using Google OAuth. RBAC was implemented as an authorization solution with limited access based on a white list with the three roles: user, admin, and superadmin. The work in this report contributes to gathering navigation links under a dynamic navigation bar, along with logistics and CRM from pyramid. Future development of the system would involve gradually building generic modules for each third-party system’s API and gradually replacing them.
