Retrieve rails for a template

There are two main ways to retrieve a template’s rails and their contents:

• Retrieve all or part of the rails and related content for a template
  This approach gives the client everything it needs to render a template’s rails. It includes a pagination option for getting the rails and their content in parts (rather than all at once, which can be slow).

• Retrieve the rail structure for a template
  This approach only gives the client the structure of the template. It then needs to make separate requests to retrieve the individual rails and their contents.
