Managing messages

This section describes all the possible actions related to messaging between properties and guests after they make a reservation.

Retrieving and confirming retrieval of messages

The Messaging API queues messages on the machine account level. Every message is part of a specific conversation, which exists between two participants: Property and Guest. To make best use of this messaging queue you should:

Retrieve messages from the queue.
Confirm the successful retrieval of those messages.
This removes the retrieved messages from the queue.
Follow steps one and two until the queue is empty.

→ If you have missed or lost messages because of an outage or any other issue, you must retrieve those messages with message queries. See searching messages.

Use a cron job to handle duplicate messages

It is possible that you retrieve messages you have already confirmed. To avoid storing duplicate messages, use a cron job that periodically filters these out.

Retrieving messages

GET
https://supply-xml.booking.com/messaging/messages/latest

The GET /messages/latest request enables you to retrieve messages from a message queue on the machine account level. Every request retrieves a maximum of 100 messages.

Only links approved in the messaging security link setting are returned in API response

Our messaging security link setting in the Extranet enables properties to specify which links can be shared with their guests in messages. We show the approved links and remove unapproved links in the messages to guests and the API responses. For more information about the Extranet setting, see About the messaging security link setting.
