Built-in Faker Library Variables
The Faker library enables you to generate sample data in EchoAPI using predefined variables. These variables work like any other variable in Postman. Their values are generated at runtime, with names starting with a $, such as $guid or $timestamp.
You can directly reference these variables in request parameters, as shown below.
You can also use these variables in schemas to dynamically generate values.
The following is a list of dynamic variables whose values are randomly generated during the request/collection run.
