Overview
A company in B2B Edition corresponds one-to-one with a customer group in BigCommerce. You can do the mapping through the bc_group_id field. Once established, you cannot change this corresponding relationship. You can only delete it. Note that you cannot merge BigCommerce customer groups or B2B Edition companies.

The best practice for using these Company APIs is to maintain unidirectional data flow, with B2B Edition endpoints as the primary touchpoint. By default B2B Edition’s company operations handle modifying linked BigCommerce customer group data (add, update, and delete).
