When setting up a new Digital Server Connection using UX Studio in a Salesforce B2C Commerce sandbox, the developer needs to provide certain key pieces of information to establish the connection properly:
* Instance Hostname (B): This is the URL of the sandbox instance to which UX Studio will connect. It is crucial for UX Studio to know where to send API calls and how to access the server.
* Business Manager Username (C): This username is required for authentication and to ensure that the developer has the necessary permissions to carry out operations on the server.
* Business Manager Password (E): This password, paired with the username, authenticates the connection to the Commerce Cloud instance.
These items are necessary for setting up the server connection correctly and securely, allowing the developer to perform tasks and deploy code directly through UX Studio.
Other options such as Instance Version (A) and Keystore Password (D) are not directly required for setting up a typical Digital Server Connection in UX Studio.
