Can any one help me how to Virtualize the API response in parasoft

Hi swapna0707, you can create a Parasoft Virtual Asset (PVA) with the response using Virtualize and hit the end point of the PVA.

For example, you can create one PVA with one responder, and use the API response as the response in the responder. After the PVA is deployed, find it in the server panel, then you can find the endpoint of the PVA by double clicking it. Once you have the endpoint, simply send request to it using your browser, curl/wget, tools like postman, or Parasoft SOAtest.

Virtualize should do it. Here is a list of useful video: https://www.parasoft.com/support/service-virtualization-and-api-testing-how-to-videos/ and you might want to take a look at "Create a virtual asset from sample request/response pairs".
