Modify Variable

The Modify Variable step changes a variable's value during a run. Variables are defined on
the integration itself — see Integration Builder.

Configuration

Field	Notes
Variable	The variable to change
Action	Set to replace the value, Concatenate to join to it, or Add Element / Remove Element for array variables
Value	The value to set, join or add
Position	Where an element goes or is taken from — Beginning, End, First or Last
Direction	The direction the operation is applied
Destination Variable (optional)	Write the result into a different variable, leaving the original untouched

When you define a variable that will be set during the run, leave its value blank on the
integration and set it here.
Destination Variable is what lets you derive a value without destroying the original —
useful when both the raw and the transformed value are needed later.
Array actions pair with Loop: collect results into a variable as you iterate, then
use the assembled array after the loop ends.
