Custom Templating Variables
You can use variables that replace values in the URL path and payload when the HTTP request is sent. For-each loops are supported.
The template already knows a set of predefined variables, which are described in Predefined Templating Variables. Check this list before you create any custom templating variables. Chances are the variable you want to use has already been defined.
You can optionally configure custom variables if the predefined variables do not meet all your needs. When a predefined variable and a custom variable are both configured with the same variable name, the template uses the predefined variable.
The template uses Apache Velocity version 1.7 to process the variables. See the Velocity User Guidefor details about usage.
