我可以看到JSON的一些问题会导致潜在的错误。其中一个是导致MALFORMED_REQUEST错误的原因，另两个是修复后可能遇到的原因。

首先，payee对象实际上将位于transactions对象的下面，因此该节点看起来应该类似于：

"transactions": [{
    "amount": {
        "currency": "USD",
        "total": "156.00",
        "details": {
            "shipping": "23.00",
            "tax": "0.00",
            "subtotal": "133.00"
        }
    },
    "payee": {
        "email": "SANDBOX MERCHANT EMAIL"
    },
    "item_list": {
        "items": [{
            "name": "PRODUCT NAME",
            "sku": "PRODUCT SKU",
            "quantity": 1,
            "price": "133.00",
            "tax": "0.00",
            "currency": "USD"
        }],
        "shipping_address": {
            "recipient_name": "Sandbox Buyer",
            "line1": "SHIPPING ADDRESS LINE 1",
            "line2": "",
            "city": "SHIPPING CITY",
            "state": "ST",
            "postal_code": "ZIP",
            "country_code": "US"
        }
    },
    "invoice_number": "25",
    "notify_url": "NOTIFY URL"
}]

接下来，在payee对象中，同时指定email和merchant_id。只需要其中一个。有一个小怪癖发生时，这两个添加，可能没有正确匹配，将产生一个错误。具体错误如下所示：

{"response":{"name":"PAYEE_ACCOUNT_INVALID","message":"Payee account is invalid.","information_link":"https://developer.paypal.com/docs/api/#PAYEE_ACCOUNT_INVALID","debug_id":"feefw4543a1a5","httpStatusCode":400},"httpStatusCode":400}
