    • Use notification variables to display dynamic information in the body of a notification such as a field value, a link to a record, or a link to system preferences.

    Sintaxe

    Specify a notification variable using this syntax:

    ${variable-name+variable-parameters}

    The variable-name portion is always required. Not all notification variables support the variable-parameters portion. When available, most variable parameters are optional. See the list of available notification variables for variable names and available parameters.
