现在该怎么创建商家现金券？？？

{"country":"","watermark":{"appid":"","timestamp":1618997042},"gender":0,"province":"","city":"","avatarUrl":"https://thirdwx.qlogo.cn/mmopen/vi_32/POgEwh4mIHO4nibH0KlMECNjjGxQUq24ZEaGT4poC6icRiccVGKSyXwibcPq4BWmiaIGuG1icwxaQX6grC9VemZoJ8rg/132","openId":"","nickName":"微信用户","language":""}
