Magic Variables

There is a predefined set of magic variables that you can use in your HTTP requests.

They all start with a $ sign.

A Unique User Identifier (UUID) is a 128-bit number used to identify information in computer systems.

  • {{$uuid}} - Generates a UUID.
  • {{$timestamp}} - Generates a timestamp.
  • {{$date}} - Generates a date (yyyy-mm-dd).
  • {{$randomInt}} - Generates a random integer (between 0 and 9999999).

To test this feature, create a file with the .http extension and write your HTTP requests in it.
