Estimote cloud API endpoint for Telemetry packets

I have built a Raspberry Pi Python program to receive and parse the proximity beacon telemetry A and B packets according to

I now wish to forward the telemetry A and B messages into my Estimote cloud account, which presumably can be done using the API However, it is not clear from the API docs which API endpoint to use.

Which API endpoint should the telemetry data be POSTed to, and what is the json schema of the POSTed data?
