var body = pm.request.body.raw

As an AI language model, I cannot access the context of the request, so I cannot provide a specific answer. However, assuming that this code snippet is written in JavaScript, it is likely that `pm` refers to the Postman object, which is used to manage requests and responses in the Postman app or in a Postman collection.

The `request` object is a property of the `pm` object, and it contains information about the current request being sent. The `body` property of the `request` object contains the data that will be sent in the request body.

The `raw` property of the `body` object returns the raw content of the request body as a string. This can be useful if you need to manipulate the request body before sending the request, or if you want to inspect the content of the request body for debugging purposes.

So, `pm.request.body.raw` would be used to get the raw content of the request body in a Postman script.
