Simple HTTP - Tesla API

[Mr.D]

Hi,

Usually the bearer token is a response on the token request and is valid for x minutes (mostly 60 minutes), so i doubt that 123 is the bearer code (: 

Can you try this?

Code:

-- Load modules
require('json')
require('ssl.https')
require('ltn12')

-- Set credentials for Tesla API
username = "admin"
password = "admin"

function GetToken()
 request_token_url = 'https://owner-api.teslamotors.com/oauth/token'
 local response_body = {}
 local request_body = "grant_type=password&username=" .. username .. "&password=" .. password
 local body, code, hdrs, stat = ssl.https.request{
   url = request_token_url;
   method = "POST";
   headers =
   {
     ["Content-Type"] = "application/x-www-form-urlencoded";
     ["Content-Length"] = #request_body;
   };
   source = ltn12.source.string(request_body);
   sink = ltn12.sink.table(response_body);
 }
 if code == 200 then
   ret = table.concat(response_body)
   ret = json.pdecode(ret)
   return ret.access_token -- could be some other field, try to log ret to be sure
 end
end

-- Request token
if not API_Token then
    API_Token = GetToken()
end

function RequestFromTesla(request)
 request_url = 'https://owner-api.teslamotors.com/api/1/' .. request
 local response_body = {}
 local request_body = ""
 local body, code, hdrs, stat = ssl.https.request{
   url = request_url;
   method = "GET";
   headers =
   {
     ["Content-Type"] = "application/json";
     ["Authorization"] = "Bearer " .. API_Token;
   };
   source = ltn12.source.string(request_body);
   sink = ltn12.sink.table(response_body);
 }
 if code == 200 then
   ret = table.concat(response_body)
   ret = json.pdecode(ret)
   return ret
 else
   API_Token = GetToken() -- request a new token
 end
end

function WriteToTesla(request)
  request_url = 'https://owner-api.teslamotors.com/api/1/' .. request
  local response_body = {}
  local request_body = ""
  local body, code, hdrs, stat = ssl.https.request{
    url = request_url;
    method = "POST";
    headers =
    {
      ["Content-Type"] = "application/json";
      ["Authorization"] = "Bearer " .. API_Token;
    };
    source = ltn12.source.string(request_body);
    sink = ltn12.sink.table(response_body);
  }
  if code == 200 then
    ret = table.concat(response_body)
    ret = json.pdecode(ret)
    return ret
  else 
    API_Token = GetToken() -- request a new token
  end
end

-- Get products
products = RequestFromTesla('products')
log(products) -- Check here your Car ID

CarID = 1 -- products[1].id?

-- Get onboarding data
onboarding_data = RequestFromTesla('users/onboarding_data')
log(onboarding_data)

-- Wake up car
result = WriteToTesla('vehicles/' .. CarID .. '/wake_up')
log(result)

BR,

Hi,

If I understand your script correctly this will get me the bearer token? and then some?
I already have the token, and you are correct, it is not 123. I just wrote that because I did not want to expose the token. Doing so, the token together with the Vehicle ID/Car ID I would give everyone access to my car
In terms of how long the token last, a Tesla token lasts for 30 days before it needs to be refreshed.

I already have the Vehicle ID, which is part of the URL.
What I need is to understand how I send a POST request that includes the URL but also the bearer token... I do not know how to add the bearer token as part of my URL request...


But I see your script is way more advanced, in fear of asking too much could you explain what your script does? in terms of the different functions? I see that storing and using the response from the car adds some further potentials in terms of adding "features" to my smarthouse/tesla
