Get Task Count (POST)
Retrieves the number of tasks that fulfill the given filter. Corresponds to the size of the result set of the Get Tasks (POST) method and takes the same parameters.
Security Consideration
There are several query parameters (such as assigneeExpression) for specifying an EL expression. These are disabled by default to prevent remote code execution. See the section on security considerations for custom code in the user guide for details.
