Webhooks: Messages

Resly sends this webhook to your Notification URL for all new messages sent to or from your Resly account.

Channel Message (confirmed booking):

{
  "reslyAccountId": "resly-hotel",
  "reslyWebhookType": "message",
  "messageId": "MSG-12345",
  "messageType": "channel",
  "channelId": "AIRBNB",
  "threadId": "123456",
  "message": "Sounds good!",
  "from": "guest",
  "to": "property",
  "reservationId": "EnOqhQ0VMEgbfMYayc6E",
  "reservationStatus": "confirmed"
}

Channel Message (not yet linked to a reservation):

reservationId is an empty string ("") when the channel thread is not linked to a Resly reservation yet (for example, an enquiry). When that happens, use the threadId from this webhook with Send a message and leave out reservationId. If reservationId is present, use that instead.

Example: enquiry webhook
