Mutating the request body in Postman is something that many people need when building complex requests. Until April 2021 it was not possible to change the request body from scripts. Mutating the form-data is not also possible.

The most common use-cases are signing, encrypting, or converting the original body. But it can also be useful for creating complex payloads like dynamically adding properties or setting some random data.
