Queue task activities in Maestro BPMN processes: required fields for creating, updating, and resolving Orchestrator queue items, organized by activity.

Queue task activities create, update, and resolve Orchestrator queue items from a task in a Maestro BPMN process. Queue activities are accessed from the Action dropdown in a task's Properties panel. Queue activities are available in the following task types — refer to Tasks for the full list:

Adds a new item to an Orchestrator queue with New status.

Adds an item to a queue and waits for the item to reach a final state before continuing the process. Uses the same fields as Create queue items.

Adds multiple items to a queue in a single batch, up to 15,000 items per call.

When commit type is ProcessAllIndependently, the activity returns the list of items that failed to be added.

Removes items with New status from a specified queue.

Sets a defer date, and optionally a due date, for an in-progress transaction item, and returns the item to New status.

Updates an InProgress transaction item with a custom status string. The status is visible in Orchestrator.

Sets the final state of a transaction item to Successful or Failed.

Maestro automatically retries the task unless the underlying call fails with a 4xx error. On failure, the task returns the error code OrchestratorSetTransactionResultFailed.

For the trigger that starts a process from a queue item, refer to Events. For more information about tasks, refer to Tasks in BPMN modeling.
