Examples

The following example demonstates creating, reading, and deleting a project collaborator through the cloud API.

from base64 import b64encode
from hashlib import sha256
from time import time
from requests import get, post
BASE_URL = 'https://www.quantconnect.com/api/v2/'

# You need to replace these with your actual credentials.
# You can request your credentials at https://www.quantconnect.com/settings/
# You can find our organization ID at https://www.quantconnect.com/organization/ 
USER_ID = 0
API_TOKEN = '____'
ORGANIZATION_ID = '____'

def get_headers():
    # Get timestamp
    timestamp = f'{int(time())}'
    time_stamped_token = f'{API_TOKEN}:{timestamp}'.encode('utf-8')

    # Get hased API token
    hashed_token = sha256(time_stamped_token).hexdigest()
    authentication = f'{USER_ID}:{hashed_token}'.encode('utf-8')
    authentication = b64encode(authentication).decode('ascii')

    # Create headers dictionary.
    return {
        'Authorization': f'Basic {authentication}',
        'Timestamp': timestamp
    }

# Authenticate to verify credentials
response = post(f'{BASE_URL}/authenticate', headers = get_headers())
print(response.json())

# --------------------


# The project ID of the project to manage its collaborator
project_id = 12345678

### Create Project Collaborator
# Define collaborator ID (replace with actual user ID)
collaborator_id = 'johnny_walker'  # User ID from profile URL (e.g., https://www.quantconnect.com/u/johnny_walker)
# Send a POST request to the /projects/collaboration/create endpoint to add a collaborator
response = post(f'{BASE_URL}/projects/collaboration/create', headers=get_headers(), json={
    "projectId": project_id,  # ID of the project
    "collaboratorUserId": collaborator_id,  # ID of the user to add as collaborator
    "collaborationLiveControl": True,  # Grant live control permission
    "collaborationWrite": True  # Grant write permission
})
# Parse the JSON response into python managable dict
result = response.json()
# Check if the request was successful and print the result
if result['success']:
    print(f"Project Collaborator Created Successfully: {result}")

### Read Project Collaborator
# Send a POST request to the /projects/collaboration/read endpoint to get collaborators
response = post(f'{BASE_URL}/projects/collaboration/read', headers=get_headers(), json={
    "projectId": project_id  # ID of the project
})
# Parse the JSON response into python managable dict
result = response.json()
# Check if the request was successful and print the collaborators
if result['success']:
    print(f"Project Collaborators: {result}")

### Update Project Collaborator
# Send a POST request to the /projects/collaboration/update endpoint to update a collaborator's rights
response = post(f'{BASE_URL}/projects/collaboration/update', headers=get_headers(), json={
    "projectId": project_id,  # ID of the project
    "collaboratorUserId": collaborator_id,  # ID of the collaborator to update
    "liveControl": True,  # Grant live control permission
})
# Parse the JSON response into python managable dict
result = response.json()
# Check if the request was successful and print the collaborators
if result['success']:
    print(f"Project Collaborator Updated Successfully: {result}")

### Delete Project Collaborator
# Send a POST request to the /projects/collaboration/delete endpoint to remove collaborator
response = post(f'{BASE_URL}/projects/collaboration/delete', headers=get_headers(), json={
    "projectId": project_id,  # ID of the project
    "collaboratorUserId": collaborator_id  # ID of the collaborator to remove
})
# Parse the JSON response into python managable dict
result = response.json()
# Check if the request was successful and print the result
if result['success']:
    print(f"Project Collaborator Deleted Successfully: {result}")
