查询接口无法区分部分退款和全额退款的信息，只能通过退款和退款查询接口进行了解。

1、退款返回响应参数说明

案例：用户支付交易金额 1 元（使用优惠劵 0.01 元，实际支付 0.99 元），分别进行部分退款 0.3 元和 0.7 元（具体返回参数建议实测为准）。

支付后查询交易信息：

2、参数对比说明

接口	参数	说明
退款接口	refund_fee	退款总金额。根据 refund_fee 和 total_amont 可了解还剩余多少金额未退还。
	refund_detail_item_list	本次退款的退款使用的资金渠道。具体优惠劵等渠道如何退款根据劵说明，如按比例退款、优先退实付金额等。根据 refund_detail_item_list，将各个支付渠道的 amount 相加，可了解本次退款金额多少。
	fund_change	本次退款是否发生了资金变化。对 fund_change 必须了解为本次退款操作，若相同退款参数调用，第一次返回 fund_change=y，第二次返回 fund_change=n，但是第二次仍返回退款信息。说明：根据这点，建议是否退款成功根据退款查询接口返回具体退款参数（trade_no、out_trade_no 等）为准。
	send_back_fee	本次商户实际退回金额。 refund_detail_item_list 各个支付渠道的 amount 相加=send_back_fee。说明：在签约收单产品时需勾选“返回资金明细”才会返回。
退款查询接口	refund_amount、trade_no 等	退款查询接口是查询本次退款的详细信息，如 refund_amount（本次退款金额）。是否返回退款渠道、退款总金额等建议实际测试为准。
