Hi Nitin
There are no short cuts here. First you need to decide - are you a consumer or provider (or both) of the API's operations.
Lets assume you are a provider. So you'll need to create persistent storage for Trouble Tickets, along with business and data logic for managing these entities. And you'll need to map your internal code (lets say in Java) to the REST JSON exposure in the API, using tools such as Jackson or equivalent.
In the
Open API table, you can find a reference implementation that might assist.
Hope it helps
