Facebook Messenger Bot Daily Push Notification, How?

Question

In cnn fb messenger bot if i write subscribe they show a message like "Got it. I’ll send you top stories every day." and then they daily send me top stories at fixed time. How they do it? I created an fb bot for my site without this but i can't understand how i add this. can anyone tell me basic instruction for this?

Answer 1

The idea is simple. When you send "subscribe" to the bot, the bot server would add a record according to the sender_id to their database or memory , then the bot server could set a timer to distribute the news messages to those sender_id who have subscribed for the news.
