• Extract wso2das-4.0.0-SNAPSHOT.zip to a suitable location (say DAS_HOME).
• Navigate to DAS_Home/bin/ and run sh worker.sh.

Step 2 - Load Python Imports.

from DAS4PythonAPI.DAS4PythonClient import DAS4PythonClient

Step 3 - Connect to WSO2 DAS 4.0 via REST API and obtain SiddhiApp Management Client.

dasPythonClient = DAS4PythonClient('http://localhost:9090')
siddhiAppManagementClient = dasPythonClient.getSiddhiAppManagementClient()

Step 4 - Obtain list of Siddhi Apps published in WSO2 DAS.

print(siddhiAppManagementClient.listSiddhiApps())
