Let’s talk about how we can build your commerce project — tailored to your business, powered by Rigby
In B2B eCommerce, the platform is never a standalone system.
It sits at the center of an internal integrations ecosystem: connected to the ERP for pricing and inventory, the PIM for product data, the CRM for account relationships, the warehouse management system for fulfillment, and often a handful of other tools for payments, tax calculation, and analytics.
The quality of these integrations determines whether the operation runs smoothly or drowns in manual workarounds. And this is where many B2B platforms create their most persistent and most expensive problems.
The APIs that power these integrations are frequently inconsistent, fragmented across modules, or limited in ways that force you into brittle workarounds that break at the worst possible times.
For development teams, this fragmentation introduces complexity:
- Multiple APIs within the same platform.
- Inconsistent authentication and data formats.
- Read-only limitations or missing write capabilities.
- Separate schemas for core commerce and B2B modules.
- Gaps between admin functionality and API exposure.
This chapter analyzes how API inconsistency and schema fragmentation impact B2B API integration across leading commerce platforms – and why integration architecture is one of the most underestimated drivers of long-term platform risk.
