Get Task Count
Retrieves the number of tasks that fulfill a provided filter. Corresponds to the size of the result set when using the Get Tasks method.
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.
