set_variable

Property Manager name: Set Variable
Behavior version: The v2024-08-13 rule format supports the set_variable behavior v1.7.
Rule format status: GA, stable
Access: Read/Write
Allowed in includes: Yes

Modify a variable to insert into subsequent fields within the rule tree. Use this behavior to specify the predeclared variable_name and determine from where to derive its new value. Based on this value_source, you can either generate the value, extract it from some part of the incoming request, assign it from another variable (including a set of built-in system variables), or directly specify its text. Optionally choose a transform function to modify the value once. See Support for variables for more information.
