A user leverages Postman lo send an API request What is the default format of the request1?

When a user creates an API request in Postman and navigates to the 'Body' tab to add a payload, selecting the 'raw' option is a common practice. Postman provides a dropdown menu to specify the content type for this raw data. By default, this dropdown is set to JSON (JavaScript Object Notation). This default reflects JSON's prevalence as the de facto standard for data interchange in modern web APIs due to its lightweight syntax and ease of parsing by various programming languages.
