如何使用DocuSign应用编程接口获取现有信封收件人视图的URL？

import requests

# Step 1: 获取访问令牌
access_token = "YOUR_ACCESS_TOKEN"

# Step 2: 获取信封信息
envelope_id = "YOUR_ENVELOPE_ID"

headers = {
    "Authorization": "Bearer " + access_token,
    "Content-Type": "application/json"
}

response = requests.get(
    f"https://api.docusign.com/v2.1/accounts/YOUR_ACCOUNT_ID/envelopes/{envelope_id}",
    headers=headers
)

envelope_info = response.json()

# Step 3: 获取收件人视图URL
recipient_id = "YOUR_RECIPIENT_ID"

response = requests.post(
    f"https://api.docusign.com/v2.1/accounts/YOUR_ACCOUNT_ID/envelopes/{envelope_id}/views/recipient",
    headers=headers,
    json={
        "recipientId": recipient_id,
        "returnUrl": "YOUR_RETURN_URL"
    }
)

recipient_view_info = response.json()

# Step 4: 获取URL
recipient_view_url = recipient_view_info["url"]
print("收件人视图URL:", recipient_view_url)
