For example:
```javascript
const curDate = new Date()
const expireTime = new Date(curDate.getTime() + 2 * 24 * 60 * 60 * 1000)
const templateParams = {
activeTime: this.dateFormat(curDate, 'yyyy-mm-dd') + ' 00:00:00',
expireTime: this.dateFormat(expireTime, 'yyyy-mm-dd') + ' 23:59:59'
}
window.ap.call('addCoupon',
{
userId: 'Alipay user's userId, not openID',
templateId: 'Card package template ID from the previous step',
bizType: 'svPage',
templateParams: JSON.stringify(templateParams)
}, function(err) {
console.err(err);
})
```
# Callback after the user receives the card pack
https://api.it120.cc/**gooking**/alipayPass/b
Please change googling to your own exclusive domain name
After Alipay callback, `passId` will be saved to the "data tunnel", which can be read through the tunnel interface:
[https://www.yuque.com/apifm/nu0f75/qvaupf](https://www.yuque.com/apifm/nu0f75/qvaupf)
```javascript
WXAPI.channelDataPull('channelData_alipayPass_fetch_Alipay user ID')
```
Replace `Alipay user ID` with the real userId
You can use `passId` to query subsequent coupon issuance results.
