Haven’t had time until now to explore on what is new as Tesla continues to push updates. The latest version as of this post is v3.9.1 which is what there I decompiled and when compared to the earlier version ( I had posted (v3.8.2) , there three new REST API’s outlined below.

Service data from the car - not sure what exactly does this will. Need to try it.

   "VEHICLE_SERVICE_DATA": {
    "TYPE": "GET",
    "URI": "api/1/vehicles/{vehicle_id}/service_data",
    "AUTH": true
  }

Now, when I call that, I get a 200OK response (see below), so it is accepting the request, and that includes the bearer code in the header as expected. I don’t see anything interesting back, but that could be because my car is not in service. Maybe someone who has their vehicle in the service center can try and validate this.

{
    "response": {}
}

The next new API is a POST, for reports; and calling this just sends a 200OK back, but I don’t know what it is for. It seems very similar to the SEND_LOG method.

"SEND_REPORT": {
    "TYPE": "POST",
    "URI": "api/1/reports",
    "AUTH": true
  }

The next two set of APIs seem quite interesting and related t AutoPilot upgrade. It might be that these could be in app purchases - checking the eligibility, and then allowing one to purchase.

"UPGRADE_ELIGIBILITY": {
    "TYPE": "GET",
    "URI": "api/1/vehicles/{vehicle_id}/eligible_upgrades",
    "AUTH": true
  },
  "AUTOPILOT_UPGRADE_URL": {
    "TYPE": "GET",
    "URI": "api/1/vehicles/{vehicle_id}/purchase_url",
    "AUTH": true
  }

When I try and call the Purchase_URL, I get a HTTP 400, and seems like I am missing some parameters - other than the headers.

{
    "error": "bad_request",
    "error_description": "The data given to this server does not meet our criteria."
}

And calling the eligible_upgrades I get a 'false'. Now I already have AutoPilot, so this might make sense. And given this seems to be a key-value pair, I am guessing there will be other things that Tesla would add over time to up-sell.

{
    "autopilot": false
}

The final new API is related to energy sites, and something I of course don’t have or have an interest, but sharing here if someone does care. :)

"CALENDAR_HISTORY_DATA": {
    "TYPE": "GET",
    "URI": "api/1/energy_sites/{site_id}/calendar_history",
    "AUTH": true
  }

I am not publishing the full API here as there aren’t significant changes. You of course can see the older post which has the details.
