When you receive an inbound message from webhooks, you can use this endpoint to mark the message as read. Messages marked as read display two blue check marks alongside their timestamp.
Marking a message as read will also mark earlier messages in the conversation as read.
We recommend marking incoming messages as read within 30 days of receipt. You cannot mark outgoing messages you sent as read.
If there is no conversation between your business phone number and customer phone number, i.e., more than 24 hours have passed since the customer last replied to you, marking the message as read will fail.
