My twilio message gets send but i don't see the message

Question

I am using the Twilio API to send messages to people who have joined my WhatsApp sandbox every 6 hours. When I check my heroku logs, I can confirm that the messages were sent, since in my code, in the send_coronavirus_data function, I print: message.sid , and when I do hero logs, this part tells me that the SIDs were successfully printed

The problem is that I don't see the message when I switch to WhatsApp.

Answer 1

There is a 24 hours window for free form messages. After that window, you must use a WhatsApp message template to intimate conversation to the WhatsApp participant and they must respond for the next 24 hour free form window to open. Look in the Twilio console messages logs to see if this is the case.
