These events state the status of the message sent using the send message API to the WhatsApp API client(which essentially sends out a message to the customer). The WhatsApp Business API client will send notifications to inform you of the status of the messages between you and users. When you send a message successfully, you will receive a notification on your callback URL stating when the message was sent, delivered, and read. The order of these notifications in your app may not reflect the actual timing of the message status. View the timestamp to determine the timing, if necessary. The notifications you may receive are:

The read event is received when the message sent by your business is read by the user. Read notifications will only be available for users who have read receipts enabled. For users that do not have it enabled, you will only receive the delivered notification.

For status to be read, it must have been delivered. In some scenarios, such as when a user is on the chat screen and a message arrives, the message is delivered and read almost simultaneously. In this or other similar scenarios, the given notification will not be sent back, as it is implied that a message has been delivered if it has been read.

The delete event is received when a user deletes a message which they have sent to your WhatsApp Business API.

Others

Other events are miscellaneous events received asynchronously on your callback. These are ad hoc events received from your WABAs docker.
