Switch
This action evaluates specific conditions in the flow. Based on the result of the evaluation, the switch directs the flow to different paths called cases.
By default, case 1 is set as the default case. The default case has no condition and cannot be deleted. Users have the option to designate any case as the default. The flow continues to run depending on which of the conditions is met. A flow can have more than two cases. Click
