If you want to cancel a coupon that is being shared, you can do so before it is claimed by your friends.
```javascript
WXAPI.couponsShareClose(token, id)
```
+ token user login credentials
+ id The coupon id that needs to be shared
```json
{
"code": 0,
"msg": "success"
}
```
After revocation, the previous coupon sharing key will become invalid immediately and friends will not be able to receive the coupons.
