Slack Stars API

The Slack Stars API is a set of Web API methods that let apps manage a user's starred itemsSlack's legacy personal bookmarking feature. It allows adding or removing a star on items such as messages (via channel and timestamp), files, and file comments, and listing all items a user has starred, typically with pagination and basic metadata. Stars are user-specific and don't alter the underlying content; they simply mark things for quick reference. Note that Slack has moved toward Saved items and other mechanisms in the client, and the stars.* methods have been deprecated, so availability and support may be limited.
