July 2024

To maintain the security of our platform and continue building trust with our lodging partners and travelers, we are implementing a new moderation process where a subset of Expedia Group messages may be flagged and held for review before being released. Two enhancements were introduced:

  • Added the reviewStatus field to the MessageThreadMessage object, to indicate a review's status as it goes through moderation. "In Review" indicates that a message is currently being reviewed (could take up to 24 hours), "Approved" indicates that the message has been approved, and "Blocked" indicates that the message contains offending material or links.
  • MessageAttributesUpdated event type was added to send a webhook notification when a message's review status changes.

To support message moderation, update your integration as follows:

  1. Add reviewStatus to every MessageThreadMessage query — Include the reviewStatus field when querying messageThread or message so you can determine the current moderation state of each message.
  2. Subscribe to MessageAttributesUpdated — If you have not already done so, add this event type to your webhook subscription. All three event types (MessageThreadCreated, MessageReceived, and MessageAttributesUpdated) are required.
  3. Handle the MessageAttributesUpdated webhook — When this notification is generated, re-query the message to get the updated reviewStatus.
  4. Persist reviewStatus locally — Store the moderation status so your UI can reflect it accurately.
  5. Filter messages by status — Only display messages with reviewStatus: APPROVED to travelers; suppress or hold messages with IN_REVIEW status (may take up to 24 hours to resolve).
  6. Handle BLOCKED messages — If reviewStatus is BLOCKED, the message contains disallowed content. Discard it or alert the property.
June 2024

When retrieving message threads, you can now specify whether they are returning in ascending or descending order based on creation date. The orderBy input parameter is now available. You can also specify the order of messages that are retrieved using the messageThread query.
