Railsのストライプwebhookイベントからストライプデータを取得する方法

Question

ストライプwebhookをレールに実装する場合、JSON形式でイベントオブジェクトを取得できます。しかし、問題は、JSONを入れ子にしたamount、subscription_idなどの属性を取得できないことです。これらの値をクラスオブジェクトから取得することもできません。これらの値を抽出する方法を教えてください。など

#<Stripe::Invoice:0xebc79c id=in_1AwVDUHb727hqFGZ0UF7B8tB> JSON: { 
    "id": "in_1AwVDUHb727hqFGZ0UF7B8tB",

} 

私はCUSTOMER_IDのような値を取得したい、subscription_id、plan_id、 はどうやってデータを抽出します：

invoice = Stripe::Invoice.retrieve(:id => "in_1AwVDUHb727hqFGZ0UF7B8tB") 

そして、私は次のような応答を取得します。

は、事前に例えば

Answer 1

あなたがretrieved the invoiceをしたら、あなたは、単にアクセスできるオブジェクトの属性をありがとう：

invoice = Stripe::Invoice.retrieve("in_...") 
customer_id = invoice.customer 
subscription_id = invoice.subscription 

あなたが必要があると思いますので、計画のIDを有していない請求書〜retrieve the subscription最初に：

subscription = Stripe::Subscription.retrieve(subscription_id) 
plan_id = subscription.plan
