从JSON提取特定密钥

我正在使用请求库，Python 3.6和SMS平台的Swagger API。我对如何从此JSON层次结构中提取特定的key：value感到有些困惑。

这是API文档的URL：api docs

我正在尝试根据ID向端点查询特定的电话号码。

这是要查询的URL：https：//api.kenect.com/v1/conversations/ \ * \ * ID \ * \ *这是JSON层次结构，因此我想使用“ phoneNumbers”键和“数字的值：

  "read": true,
  "responded": true,
  "snippet": "string",
  "subject": "string",
  "updatedDate": 1514801105185
}

最后，这是我正在尝试的代码。我曾使用类似的功能从同一端点获取消息正文，但不适用于电话号码。

url='https://api.kenect.com/v1/conversations/'
h = {'accept': recContentType,
    'content-type': recContentType,
    'x-api-token': apiToken,
    'x-api-Key': apiKey}
p={'id': id}

response=requests.get(url + id, headers=h, params=p).json()

for item in response['phoneNumber']:
    pnum = item['number']
    print(pnum)

我在这里做错了什么？
