name `string`	Name of the flow. Must be unique for each flow. To check the name, you can use the method tasks.flow.Flow.isExists
description `string`	Description of the flow
groupId `integer`	Identifier of the group to which the flow will be linked. If not specified, a new group will be automatically created
ownerId `integer`	Identifier of the flow administrator. If not specified, the creator of the flow will be the administrator
templateId `integer`	Identifier of the template that users will use to add tasks to the flow
plannedCompletionTime* `integer`	Planned time to complete the task in seconds

For example: `[ [ 'user','3' ], [ 'department','17:F' ] ]` If you do not add the suffix `:F`, the system will select all sub-departments of the specified department according to the company structure. To allow all users to add tasks, specify the value `{"meta-user": "all-users"}`
