Pause Pause

yaml
type: "io.kestra.plugin.core.flow.Pause"

Pause the current execution and wait for a manual 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 (marked in purple) and you can 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 a timeout.

Properties

delay

  • Type: string
  • Dynamic: ❌
  • Required: ❌
  • Format: duration

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

The delay is a string in the 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 delay and no timeout are configured, the execution will never end until it's manually resumed from the UI or API.

errors

  • Type: array
  • SubType: Task
  • Dynamic: ❌
  • Required: ❌

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

onResume

  • Type: array
  • SubType:
  • Dynamic: ❌
  • Required: ❌

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.

tasks

  • Type: array
  • SubType: Task
  • Dynamic: ❌
  • Required: ❌

timeout

  • Type: string
  • Dynamic: ❌
  • Required: ❌
  • Format: duration

Timeout of the pause — useful to avoid never-ending workflows in a human-in-the-loop scenario. For example, if you want to pause the execution until a human validates some data generated in a previous task, you can set a timeout of e.g. 24 hours. If no manual approval happens within 24 hours, the execution will automatically resume without a prior data validation.

If no delay and no timeout are configured, the execution will never end until it's manually resumed from the UI or API.
