# Stickers — Expire

The LiSA Player dispatches a message when an active sticker expires.

This message is sent by the LiSA Player to the host app / environment.

### Properties

Along with all standard [Sticker message properties](https://docs.hello-lisa.com/developers/guides/player-communication/message-api-reference/stickers/..#properties), an **Expire** message includes the following additional properties:
