Using external ids to send measurements/alarms – Cumulocity

Hi,

Is the global Id the only way to send data for a device or can I use the external ID?
If we write a client or app but we have access mainly to an external id (serial number or whatever id), I either
- keep a mapping table
- Every time I get data I need to ask the identity api for the global Id, and then i use the measurement API to send the data.

Thanks
marcos.
