Text Data equal expression Unique values

  • Return Unique true when matches regardless of the number of matches occurred per evaluation.

This plugin loads the entire message into RAM, so make sure to apply this function only on small messages.

How to use

To use the equal function, the Content parameter should contain text/string (otherwise it will fail and you will end up with a garbage result). But first and foremost we have to configure the Formula plugin:

  • Select Formula as the expression type plugin.
  • Write down the expression to use in the 'Expression' text area.
  • Input proper Content as a parameter to the function.


Use the equal function with any of the following parameters:

  • From Message Body: equal('Expression',body)

  • From Message Context: equal('Expression',context('MessageContextKey'))

  • Result from previous Formula operation equal('Expression',SomeOtherNestedFormulaFunction(Content))
