附原文地址：微信支付商户免充值代金券接口升级验收脚本 用例组合1001+1002+1003+1004+1005（强迫症专用）? - 微信开放社区 https://developers.weixin.qq.com/community/develop/article/doc/0002e82b060c3028230c915f150813

1，为什么要升级？

开通免充值代金券后，几个支付相关接口参数会发生变动，需要改相应代码适配变动。

详见：开通免充值业务API接口升级详情 https://pay.weixin.qq.com/wiki/doc/api/download/ptsh_mczjksj.pdf

2，官方的测试验收示例

详见：https://pay.weixin.qq.com/wiki/doc/api/download/mczyscsyl.pdf

3，接口升级验收进度查询

详见：https://pay.weixin.qq.com/wiki/doc/api/tools/sp_coupon.php?chapter=15_6&index=4

4，使用自动升级验收脚本前的重要提醒！

请务必去改自己的应用层代码，这里只是方便统一验收用。

5，自动升级验收脚本代码（PHP版）
