Hi @Makoto Oda ,
To check the status for a durable function, you will need a WebActivity after calling the durable function and then an if-else activity to check the status. Please see the screenshots below. Thanks!
@activity('Retrieve XXX').output.statusQueryGetUri
@contains(toUpper(activity('Wait for Completion').output.runtimeStatus), 'COMPLETE')
--please mark the answer as accepted, if it was helpful. Thanks--
