I need to send my customers a reminder from time to time via whatsapp. It has to go at a particular time on the date that they have chosen to attend a Masterclass I am conducting. I know that I can create an whatsapp contact via API and then trigger a flow to send a message but I want to send messages multiple times as reminder. What’s the best way to go about this case? If there’s an API call that can trigger a message or a particular flow then it would be helpful. The logic of the time of calling this API can be taken care of in my CRM.
Example:- A customer registers for the workshop on Monday. I have to send him a reminder at 4:00 PM on Thursday.

My suggestion is to set a custom field with the date/time of the workshop, and them use that custom field to trigger the messages.
You can set the triggers X hours/days before or after the event.


I’ve done this setup multiple times for calendar events + reminders and follow up, it works great.
