如何取消用户订阅用户googleapipythonclien

Question

我想用python从服务器端代码中取消用户订阅。我已经使用googleapi来验证用户订阅。API端点如下所示。你知道吗

GET https://www.googleapis.com/androidpublisher/v2/applications/{packageName}/purchases/subscriptions/{subscriptionId}/tokens/{token}

我用python实现了这个

service = build(serviceName='androidpublisher', version='v2', credentials=cred)
response = service.purchases().subscriptions().get(
            packageName=receipt_json.get('packageName'),
            subscriptionId=receipt_json.get('productId'),
            token=receipt_json.get('purchaseToken')).execute()

取消订阅的端点如下所示。你知道吗

POST https://www.googleapis.com/androidpublisher/v2/applications/{packageName}/purchases/subscriptions/{subscriptionId}/tokens/{token}:cancel

如何在googleapi python客户端中实现这个:cancel？你知道吗
