如何在Bitrix24上用Python设置任务截止日期？

import requests

# Bitrix24 API endpoint
api_endpoint = 'https://your-bitrix24-domain/rest/task.item.update.json'

# Bitrix24 authentication credentials
auth_params = {
    'auth': 'your-authentication-token'
}

# Task ID and new deadline
task_id = 12345
new_deadline = '2022-12-31'

# Request payload
payload = {
    'id': task_id,
    'fields': {
        'DEADLINE': new_deadline
    }
}

# Send API request
response = requests.post(api_endpoint, params=auth_params, json=payload)

# Check response status
if response.status_code == 200:
    print('Task deadline updated successfully.')
else:
    print('Failed to update task deadline.')
