[Documentation index](../llms.txt)

Use this method to clear the list of pinned messages in a chat. In private chats and channel direct messages chats, no additional rights are required to unpin all pinned messages. Conversely, the bot must be an administrator with the 'can\_pin\_messages' right or the 'can\_edit\_messages' right to unpin all pinned messages in groups and channels respectively. Returns *True* on success.
