Which B2C feature allows a developer to manually change the service URL from the sandbox?

The feature that allows a developer to manually change the service URL from the sandbox is accessed through the service credential URL field. This field is specifically designed for developers to configure and manage service connections, allowing for adjustments to the endpoint that the application will use when making service requests.

When working within the B2C Commerce framework, managing service URLs effectively is crucial, particularly in different environments, such as sandbox and production. The service credential URL field provides the necessary flexibility to input a custom URL, which can point to a different service endpoint than the default. This is particularly valuable for testing and development purposes, as it allows a more controlled and tailored environment for integration without affecting the live environment.

Utilizing the other options may lead to mistakes or misconfigurations. For instance, while service status areas and preferences are integral parts of the setup, they typically do not provide the direct means to override the URL settings in the same manner as the service credential URL field does. Thus, the direct utilization of the service credential URL field is the most effective and appropriate method for achieving the desired outcome.
