Steps
Enable the Configuration API service in KEPServerEX (default endpoint http://localhost:57412)
Issue GET http://localhost:57412/config/v1/project/_profile_library/profiles/{profile_name} to inspect an existing profile, or GET on other /config/v1/project/... paths to read current objects
Issue POST http://localhost:57412/config/v1/project/channels with a JSON body to create a new channel (e.g. a Modbus TCP/IP Ethernet channel)
Use PUT to update existing channel/device/tag objects and DELETE to remove them, following the same /config/v1/project/... resource paths
Consider using PTC's official Kepware-ConfigAPI-SDK-Python to wrap these calls instead of building raw HTTP requests
Known gotchas
Documentation and examples assume the client runs on the same machine as the server using the default HTTP port — production deployments must switch to HTTPS and a non-default host/port
Every GET returns all properties of an object; there is no partial/sparse read, so large projects can produce large responses
