Pause

Pause the current execution and wait for approval (either by humans or other automated processes).

All tasks downstream from the Pause task will be put on hold until the execution is manually resumed from the UI.

The Execution will be in a Paused state, and you can either manually resume it by clicking on the "Resume" button in the UI or by calling the POST API endpoint /api/v1/executions/{executionId}/resume. The execution can also be resumed automatically after the pauseDuration.

Default RESUME

Possible Values

RESUMEWARNCANCELFAIL

Pause behavior, by default set to RESUME. This property controls happens when a pause task reach its duration.

Tasks that are resumed before the duration (for example, from the UI) will not use the behavior property but will always succeed. Possible values are:

RESUME: continues with the execution
WARN: ends the Pause task in WARNING and continues with the execution
FAIL: fails the Pause task
CANCEL: cancels the execution

Format duration

Duration of the pause — useful if you want to pause the execution for a fixed amount of time.

Deprecated: use pauseDuration instead.

SubType

List of tasks to run if any tasks failed on this FlowableTask.

SubType

A runnable task that will be executed when it's paused.

Inputs to be passed to the execution when it's resumed.

Before resuming the execution, the user will be prompted to fill in these inputs. The inputs can be used to pass additional data to the execution, which is useful for human-in-the-loop scenarios. The onResume inputs work the same way as regular flow inputs — they can be of any type and can have default values. You can access those values in downstream tasks using the onResume output of the Pause task.

Format duration

Duration of the pause. If not set, the task will wait forever to be manually resumed except if a timeout is set, in this case, the timeout will be honored.

The duration is a string in ISO 8601 Duration format, e.g. PT1H for 1 hour, PT30M for 30 minutes, PT10S for 10 seconds, P1D for 1 day, etc. If no pauseDuration and no timeout are configured, the execution will never end until it's manually resumed from the UI or API.
