【问题描述】：

我试图弄清楚在申请订阅我创建的网络服务时如何传递自定义变量； 到目前为止，我的前端代码如下所示：

const createSubscription = (data, actions) => 
    return actions.subscription.create(
        'plan_id': 'P-XXXXXXXXXXX',
        "custom": "This is data from custom field",
        "custom_id": "This is data from custom_id field"
    );
;

但是当我的客户端被批准后，IPN 向我的后端服务器发送通知，根本没有custom_id 或custom 的字段：

  mc_gross: '100.00',
  outstanding_balance: '0.00',
  period_type: ' Regular',
  next_payment_date: '03:00:00 Mar 17, 2021 PDT',
  protection_eligibility: 'Eligible',
  payment_cycle: 'Monthly',
  address_status: 'confirmed',
  tax: '0.00',
  payer_id: 'HXRWYDXHYFZN8',
  address_street: '1 Main St',
  payment_date: '10:45:14 Feb 17, 2021 PST',
  payment_status: 'Completed',
  product_name: 'Monthly Plan',
  charset: 'UTF-8',
  recurring_payment_id: 'I-F2C2YTJU2E1U',
  address_zip: '95131',
  first_name: 'John',
  mc_fee: '3.20',
  address_country_code: 'US',
  address_name: 'John Doe',
  notify_version: '3.9',
  amount_per_cycle: '100.00',
  payer_status: 'verified',
  currency_code: 'USD',
  business: '[e-mail]',
  address_country: 'United States',
  address_city: 'San Jose',
  verify_sign: 'AwvhmU0vP2FlU28Jc6pBhDPQLGvKAuK1SbOO3rAWZruMDt8v8SJ',
  payer_email: '[e-mail]',
  initial_payment_amount: '0.00',
  profile_status: 'Active',
  amount: '100.00',
  txn_id: '7M8958705N109551P',
  payment_type: 'instant',
  last_name: 'Doe',
  address_state: 'CA',
  receiver_email: '[e-mail]',
  payment_fee: '3.20',
  receiver_id: '5CCP2BYDNEBQE',
  txn_type: 'recurring_payment',
  mc_currency: 'USD',
  residence_country: 'US',
  test_ipn: '1',
  transaction_subject: 'Monthly Plan',
  payment_gross: '100.00',
  shipping: '0.00',
  product_type: '1',
  time_created: '10:44:22 Feb 17, 2021 PST',
  ipn_track_id: 'bee6f9133b8f'

有什么方法可以传递一些额外的信息，以便我可以更新我的后端记录？

PS。请注意，这是createSubscription 而不是createOrder 或类似的东西。

【参考方案1】：

custom_id 是correct value

您可能只会在webhook event notifications 中收到它，而不是 IPN（这是一项非常古老的服务，不打算与当前 API 一起使用）

最好的解决方案是从您的服务器创建并激活订阅。 The answer here 和它链接的其他答案以获得一些信息。
