除上述IPN之外，您应该会收到另一个IPN，其中包含以下内容，并且还包含您唯一的ID：
[0] => txn_type=masspay
[1] => payment_gross_1=1.00
[2] => payment_date=11%3A50%3A03+Aug+24%2C+2015+PDT
[3] => last_name=XXX
[4] => mc_fee_1=0.02
[5] => masspay_txn_id_1=42507771L0091684X
[6] => receiver_email_1=XXXX
[7] => residence_country=US
[8] => verify_sign=XXXX
[9] => payer_status=verified
[10] => test_ipn=1
[11] => payer_email=XXXX
[12] => first_name=XXXX
[13] => payment_fee_1=0.02
[14] => payer_id=XXXXX
[15] => payer_business_name=XXXX
[16] => payment_status=Completed
[17] => status_1=Completed
[18] => mc_gross_1=1.00
[19] => charset=UTF-8
[20] => notify_version=3.8
[21] => mc_currency_1=USD
[22] => unique_id_1=ID001
[23] => ipn_track_id=86016e15b5f50
