@Deepak.kumavat, there are API calls that let you retrieve details of instrument lists, report templates, and schedules. Most of them use an ID specific to the list, template or schedule, but the ID can easily be retrieved from the name. All these calls are documented in the API reference tree (all links that follow point to that API Reference). Here is a short list of possibilities:

• Instrument list: get by name (retrieve ID using list name), get all instruments (list all instruments in a list), get details of an instrument list, get all instrument lists.
• Report template: get by name (retrieve ID using list name), get content fields of a template, get details of a template, get all templates.
• Schedule: get by name (retrieve ID using list name), get details of a schedule, get all schedules, get data availability / trigger information for all of the instruments in the referenced instrument list of a schedule. You can also get details of the last extraction, next extraction and pending extractions of a schedule.

For examples, see the following

• The C# example application, described in the DSS Quick Start, contains a set of example uses of these calls (for instruments, report templates and schedules). That application displays the C# code, as well as the HTTP requests and responses, for all these calls.
• Among the Java samples available under the DSS REST downloads tab you will find DSS2Instruments that illustrates some of those for instruments, and DSS2ReportTemplates that does something similar for report templates.

I hope this helps. If not, please specify exactly what you need, and I will try to give you more detailed information and refer you to the API calls that will do what you need.
