实现如下：

温馨提示：◆ 给同一个实名用户付款，单笔单日限额2W/2W◆ 给同一个非实名用户付款，单笔单日限额2000/2000◆ 一个商户同一日付款总额限额100W◆ 仅支持商户号已绑定的APPID；◆ 针对付款的目标用户，已微信支付实名认证的用户可提供校验真实姓名的功能，未实名认证的用户无法校验，企业可根据自身业务的安全级别选择验证类型；◆ 付款金额必须小于或等于商户当前可用余额的金额；◆ 已付款的记录，企业可通过企业付款查询查看相应数据。
到账 付款资金将进入目标用户的零钱（微信-我-钱包-零钱）。微信支付将做零钱入账消息通知，零钱收支明细会展示相应记录。
温馨提示：针对无零钱账户的历史客户端版本，资金将进入用户的红包账户，微信支付无消息通知用户，企业可选择自行触达用户。
