What is new: D365 Commerce CSU
Introduction
There are no official Microsoft Release Notes on the latest D365 Commerce (Retail) Cloud Scale Unit (CSU) APIs. Since more and more companies are starting to use these APIs for integrating external e-commerce websites with D365 ERP, I think the community may appreciate some ‘unofficial’ Commerce CSU “WHAT’S NEW” 😎.
Besides that, the ‘official’ list of APIs is not really kept up-to-date here on Microsoft learn, so below you’ll find links to the latest API documentation, an up-to-date list of all APIs and what role they’re designed for (Customer = website, Employee/Device = store, Application = server-to-server).
Release notes | Latest version
The latest Commerce CSU version which is used for the Release notes here is:
The version is compared with 9.49 (10.0.39).
Removed APIs
/Commerce/GetOrdersByStore
/Commerce/GetPickUpOrdersByStore
New APIs

Note on Roles vs Use:
- Anonymous/Customer/BusinessPartner = e-commerce
- Employee/Device = In-store
- Application = Server-to-Server
As per this list, it becomes clear that Microsoft is investing to expose Copilot/ERP backend generated summary information through the CSU. Unfortunately, this is currently only designed for use in-store (role = employee), but it should be possible to extend this.
Data Model changes

The list above demonstrates investment in the following areas:
- Self checkout POS (in-store): more detail
- Copilot Summaries: more detail
- New search criteria for stock availability

I’ve been integrating non-Microsoft e-commerce solutions with D365 ERP and CRM since the early days of AX for Retail in 2009. Already back in 2015, I connected an E-commerce platform to D365 ERP by a predecessor of the current D365 Commerce CSU for the first time.
