# News: Messaging API update for December 2020

Messaging API update for December 2020

We added a new property to the Sticker message type of the Message webhook event object of the Messaging API.

# keywords property

Previously, developers were unable to understand the context of the stickers sent to the LINE Official Account by looking at the returned webhook event object. Now, with the keywords property, you can.

  "destination": "xxxxxxxxxx",
  "events": [
      "replyToken": "nHuyWiB7yP5Zw52FIkcQobQuGDXCTA",
      "type": "message",
      "mode": "active",
      "timestamp": 1462629479859,
      "source": {

        "userId": "U4af4980629..."
