No problem, happy to help!
Regarding your follow-up question: the MESSAGE_DELIVERY trigger delivers receipts for most messages sent using the Conversation API. This includes messages that belong to paid WhatsApp conversation types, messages that belong to service or free entry point WhatsApp conversation types, and other messages that are sent on any of the supported Conversation API channels.
Additionally, the message_metadata field will indicate when a message belongs to a service or free entry point conversation. An example of a receipt that corresponds to a message sent during a service conversation can be seen in our documentation on receiving WhatsApp pricing information in delivery receipts.
You may also want to review Meta's rules regarding free entry point conversations, as some of the corresponding time limits appear to be different than other conversation types. Specifically, it looks like free entry point conversations last 72 hours, rather than 24 hours.
Please let me know if you have any other questions. Thank you!
