Help with Tesla Powerwall API V3

[gjniewenhuijse]

Try adding User-Agent/X-Tesla-User-Agent headers as in previous examples. Also try adding client_secret field to the JSON body. You might also need an additional request to exchange bearer token for access token.

I already tried that, but same 400 deny error

Code:

function GetToken()
  body = json.encode({
    grant_type = 'authorization_code',
    client_id = 'ownerapi',
    client_secret = client_secret,
    refresh_token = refreshToken,
    scope = 'openid email offline_access'     
  })

  resp = {}

  res, code, headers = http.request({
    url = 'https://auth.tesla.com/oauth2/v3/token',
    method = 'POST',
    source = ltn12.source.string(body),
    sink = ltn12.sink.table(resp),
    headers = {
      ['Content-Type'] = 'application/json',
      ['Accept'] = 'application/json',
      ['Content-Length'] = #body,
      ['User-Agent'] = 'Mozilla/5.0 (Linux; Android 9.0.0; VS985 4G Build/LRX21Y; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/58.0.3029.83 Mobile Safari/537.36',
        ['X-Tesla-User-Agent'] = 'TeslaApp/3.4.4-350/fad4a582e/android/9.0.0'
    }
  })
 
  log(res, code, headers)
end
