Hi, 

I am trying to read my live portfolio's log via API but am unable to get it to work.

Have verified that the API call's authentication is working, and tested with getting project's detail which also work. 

For /live/read/log  there is an algorithmId, I have set it in main.py→ Initialize using SetAlgorithmId. Is this the correct way to do it?

  1. def Initialize(self):
  3.         self.SetAlgorithmId("algoId123")
  4.         self.Debug(f"AlgorithmId is {self.AlgorithmId}")

 

Attached my API code below..

  1. #-- authentication
  2. import base64
  3. import hashlib
  4. import time
  6. #-- http call
  7. import requests
  9. #-- json formatting
  10. import json
  12. #-- CONFIGURATION
  13. api_token =  "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
  14. base_url = "https://www.quantconnect.com/api/v2"
  17. #-- GET API TOKEN
  18. timestamp = str(int(time.time()))
  19. time_stamped_token = api_token + ':' + timestamp
  20. hashed_token = hashlib.sha256(time_stamped_token.encode('utf-8')).hexdigest()
  21. authentication = "{}:{}".format(user_ID, hashed_token)
  22. api_token = base64.b64encode(authentication.encode('utf-8')).decode('ascii')
  23. # print(f"api_token: {api_token}")
  25. # Create headers dictionary.
  26. headers = {
  27.     'Authorization': 'Basic %s' % api_token,
  28.     'Timestamp': timestamp
  29. }
  31. #-- 1) AUTHENTICATION (successful)
  32. request_url = base_url + "/authenticate"
  33. response = requests.post(request_url, 
  34.                          data = {}, 
  35.                          headers = headers)
  36. content = response.text
  37. print(f"Authentication is {content}")
  40. #-- 2) READ PROJECT  (successful)
  41. request_url = base_url + "/projects/read"
  42. dataDict = {}
  43. dataDict["projectId"] = "13299999"
  46. response = requests.post(request_url, 
  47.                          data = dataDict, 
  48.                          headers = headers)
  49. content = response.json()
  50. pretty_content = json.dumps(content, indent=4)
  51. print(f"project's content is {pretty_content}")
  54. #-- 3) READ LIVE PORTFOLIO  (not working)
  55. request_url = base_url + "/live/read/portfolio"
  56. dataDict = {}
  57. dataDict["projectId"] = "13299999"
  60. response = requests.post(request_url, 
  61.                          data = dataDict, 
  62.                          headers = headers)
  63. content = response.json()
  64. pretty_content = json.dumps(content, indent=4)
  65. print(f"project's live portfolio is {pretty_content}")
  68. #-- 4) READ LIVE LOG (not working)
  69. request_url = base_url + "/live/read/log"
  70. dataDict = {}
  71. dataDict["format"] = "json"
  72. dataDict["projectId"] = "13299999"
  73. dataDict["algorithmId"] = "algoId123"
  74. dataDict["start"] = 0
  75. dataDict["end"] = 99999999999
  78. response = requests.post(request_url, 
  79.                          data = dataDict, 
  80.                          headers = headers)
  81. content = response.json()
  82. pretty_content = json.dumps(content, indent=4)
  83. print(f"project's log is {pretty_content}")
+ Expand
