    About this task

    This procedure uses the ServiceNow SDK command-line interface (CLI). From a command-line tool, enter now-sdk --help to get information about the available commands and global options. To get additional information about a command and its parameters, enter the command and --help or -h. For example, now-sdk auth --help. For more information about the CLI, see ServiceNow SDK CLI.

    Procedure

    1. Create a local directory for your application.
    2. In Visual Studio Code, open the directory.
    3. From the application directory, open an integrated Terminal window.
    4. Specify the instance to authenticate to with the auth command.
      npx @servicenow/sdk auth --add <instance>
      For example:
      npx @servicenow/sdk auth --add https://myinstance.service-now.com
      Note:
      Using the npx command installs the ServiceNow SDK in your application directory instead of globally.
    5. Respond to the following series of prompts.
