# Configure Flow: Check for String

With the "Check for String" function, you can check whether a string is contained within an entity of a function that has already run. 

For example, you can check whether the alarm message of a triggered alarm contains the string "TESTALARM" or whether the alarm was triggered by a defined tag.
