Corporate action announcements are notifications from a company’s board of trustees about a reorganization event that materially impacts shareholders. Alpaca’s announcement database contains previous and upcoming corporate actions that are made available to you shortly after the announcement’s declaration date. The Corporate Actions API: Announcements will give you access to detailed information on four categories of corporate action announcements: dividends, mergers, spinoffs, and stock splits.

For more information on the corporate action types and how to get started with Alpaca’s API, please view our Learn Article, or jump straight into our developer documentation for Trading API or Broker API.
