Wait API

The atomic action can be used to wait for the target object to reach the expected state. For example, after calling the StartServer API of the ECS using the Execute API atomic action, call the ShowServer API of the ECS using the Wait API atomic action. Wait until the status in the API response becomes ACTIVE, that is, the status is running, then you can confirm that the ECS instance has been started.

Click Input, select service (product short name), apiName (API name),

and propertySelector (check resource property), and specify the following parameters as response fields to be used as the judgment criteria as required:
- stopRetryValues (stop retry status): Stop the current atomic action waiting.
- desiredValues (success match status): Expected match value. When the value is the same as that of propertySelector, the current atomic action is successfully executed.
- notDesiredValues (success unMatch status): Expected unmatch value. When the value is the same as that of propertySelector, the current atomic action fails to be executed.
