I am using WhatsApp official API to send messages to customers. I want to send them a reminder message if they have not replied during a certain period of time (a couple of hours more or less). In other words, I will send a message and wait for a certain period of time for their response. If they respond, no reminder message is needed. If they don't, I will send them a reminder message. WhatsApp API sends webhook notifications when they reply.
How do I implement that in a Django view? I am thinking of creating an async process/thread each time I want to wait, and handle the timeout condition in that process somehow. Is this the right approach? I think that would be costly in terms of server time used, but I am not sure. If this is the right approach, please show some pseudo-code on how it can be done.
I will be deploying my app on Heroku.
Your answer is much appreciated..
