To register a new retail server API extension, the Retail Server web.config file must be updated. The web.config file for the Retail Server serves as the configuration file for the API and contains important settings and configurations that allow the retail server to process requests and integrate with extensions effectively. By making changes in this file, you can specify the details of the API extension, such as routes, handlers, and any necessary middleware that needs to be included.

The other choices—like the web.config files for Retail Store Front, Retail Cloud POS, or AOS Service—play different roles within the broader Dynamics ecosystem and do not directly manage the registration of retail server API extensions. The Retail Store Front web.config pertains to the configuration for the point of sale (POS) user interface, while the Retail Cloud POS web.config deals specifically with the cloud-based point of sale. The AOS Service web.config is linked to the Application Object Server and handles a different set of configurations pertinent to the overall Dynamics architecture. Thus, updating the Retail Server web.config is essential for enabling the API extension functionalities on the retail server specifically.
