taskVariables object[]
An array of filter clauses specifying the variables to filter for.
If defined, the query returns only tasks to which all clauses apply.
However, it's important to note that this filtering mechanism is
designed to work exclusively with truncated variables. This means
variables of a larger size are not compatible with this filter, and
attempts to use them may result in inaccurate or incomplete query results.
Array [
name string
The name of the variable.
value string
The value of the variable. When specifying the variable value, it's crucial to maintain consistency with JSON values (serialization for the complex objects such as list) and ensure that strings remain appropriately formatted.
operator string
Possible values: [eq]
The comparison operator to use for the variable.
* eq: Equals
]
tenantIds string[]

An array of Tenant IDs to filter tasks. When multi-tenancy is
enabled, tasks associated with the specified tenant IDs are returned;
if disabled, this parameter is ignored.

sort object[]
An array of objects specifying the fields to sort the results by.
Array [
field string
Possible values: [completionTime, creationTime, followUpDate, dueDate, priority]
order string
Possible values: [ASC, DESC]
• ASC: Ascending
  * DESC: Descending
]
searchAfter string[]

Used to return a paginated result. Array of values that should be copied from sortValues of one of the tasks from the current search results page.
It enables the API to return a page of tasks that directly follow the task identified by the provided values, with respect to the sorting order.

searchAfterOrEqual string[]

Used to return a paginated result. Array of values that should be copied from sortValues of one of the tasks from the current search results page.
It enables the API to return a page of tasks that directly follow or are equal to the task identified by the provided values, with respect to the sorting order.

searchBefore string[]

Used to return a paginated result. Array of values that should be copied from sortValues of one of the tasks from the current search results page.
It enables the API to return a page of tasks that directly precede the task identified by the provided values, with respect to the sorting order.

searchBeforeOrEqual string[]

Used to return a paginated result. Array of values that should be copied from sortValues of one of the tasks from the current search results page.
It enables the API to return a page of tasks that directly precede or are equal to the task identified by the provided values, with respect to the sorting order.

includeVariables object[]
An array used to specify a list of variable names that should be included in the response when querying tasks.
This field allows users to selectively retrieve specific variables associated with the tasks returned in the search results.
Array [
name string
The name of the variable.
alwaysReturnFullValue boolean
Default value: false
Always return the full value of the variable?
