Octopus Energy API - Import

Hi
I’m a user in the UK with Octopus Energy.
I’m on their Go tariff with a smart meter in place. They have an API and I can see my import data on their website. I wondered if anybody had found a way of using their REST API to automatically update the half hourly smart meter readings for import into PV output? It must track export too but I can’t access those figures.

Thanks
Chris
