Checkpoint

Creates a save point in the durable workflow. In case of crash, execution resumes from the last checkpoint instead of restarting.

Parameters

Parameter	Type	Required	Variable	Description
checkpointId	text	No	No	Unique checkpoint identifier (auto-generated if omitted).
saveVariables	array	No	No	List of variable names to save at the checkpoint. Enables selective recovery after a crash.
ttlMinutes	number	No	No	Checkpoint retention duration in minutes. Expires after this delay.
onRestore	choice (continue, restart)	No	No	Behavior on restore: resume from the checkpoint or restart the workflow. (Default: "continue")

Tip

Only active in durable mode (Run/Schedule). In test mode, the checkpoint is a no-op. Place it after expensive operations.
