Below is a simple example that just adds a profile without any readings. The profileName and description are both optional but are shown here for illustration purposes. The providerProfileId is also optional but has to be unique if supplied. The profile's serviceType will default to "ELECTRICITY" if not passed in (your other option is "SOLAR_PV"), and if this is the account's first profile with the "ELECTRICITY" service type, it will also have its isDefault set to true. You do not need to pass in any bills or reading data but you can if you have them.
