How is Mini Program's movie opening reminder similar to cat's eye realized?

how is the opening reminder of the cat"s eye movie Mini Program realized?

for example: I chose an afternoon movie in the morning, and then Mini Program no longer opened the cat"s eye, but 20 minutes before the opening of the movie, the cat"s eye will send me a template message to inform me. How can this be realized?

how does Mini Program judge that the movie is about to begin and send me a template message if I don"t open it?

you can take a look at the template message api of the official document


this has nothing to do with the order quantity, which is the number of users, that is, the number of clients. It is Wechat's job to send messages to the client template, even if no matter how many clients only need to call that api for Cat's Eye
