- Plug-ins
  UrbanCode plug-ins provide tools for creating component processes and integrations. IBM UrbanCode provides plug-ins for several common deployment processes, and others are available to integrate with a wide variety of tools, such as middleware tools, databases, and servers.
- Creating notification templates
  Notification templates are the basis for emails that the server sends to users after an event occurs on the server. You can create customized notification templates by modifying the default templates provided, or by creating new templates of your own.
- REST API reference
  The HCL Launch server and blueprint design server each have a separate REST interface. You can use these REST interfaces to automate tasks on those servers.
  - Running REST commands
    Many different programs can run REST commands. To run the command, you call a method on a REST resource and pass parameters or a request in JSON format.
  - Examples of REST API commands
    Many REST and command-line client commands have examples in their help topics. A few more examples using various programming languages and scenarios are provided here. The commands are similar for the server and for the blueprint design server.
  - Authenticating for REST commands
    The way that you authenticate to run REST commands depends on how the server is set up and the tool that you are using to run the commands.
  - Deploying applications by using REST commands: An example
    The following example describes how to use the REST commands to deploy an application.
