Add placeholder text

GET https://postman-echo.com/get?foo1={{somethingForThisCollection}}&foo2={{somethingForThisEnvironment}}&foo3={{variableWithNoValue}}

Qodex relies on string substitution to render variable values in the web documentation. Use placeholder text as a variable’s value to indicate what value to use. If you leave the value blank, as shown with foo3, Qodex displays no information in the documentation.
