How to automatically add coupons to card packages in WeChat applets?
Detailed explanation of the automatic card purchase plan for WeChat mini program coupons
I hope to automatically add coupons to user card packages in the WeChat mini program, without jumping to the WeChat coupon collection page? This requires the cooperation of the backend. This article will elaborate on the implementation process.
User scenario: The mini program displays a coupon list. The user clicks to collect it without jumping. It directly prompts "received successfully". The coupon is automatically deposited into the WeChat card package. wx.addCard() method will jump to the WeChat collection page, so it is not applicable.
Implementation steps:
The front-end of the mini program triggers the collection: After the user clicks to receive the coupon, the front-end of the mini program sends a collection request to the back-end server, including the coupon ID and user information.
Back-end server processing: The back-end server verifies the user's qualifications, records the collection information, and calls the WeChat Open Platform API, and uses code parameters to directly add the coupon to the user's card package. This step does not require front-end participation.
The backend returns the result: After the backend processing is completed, the success or failure information is returned to the frontend of the applet.
Tips for the front-end of the mini program: The front-end returns the result based on the back-end, and displays a prompt of "receiving successfully" or failure. The coupons have been automatically added to the user's WeChat card package by the backend ("I"-"Card Pack"-"Coupon and Gift Card").
The core lies in the backend using the WeChat API to add coupons, and the frontend is only responsible for requests and prompts to achieve a seamless collection experience.
