This endpoint provides data about the corporate actions for each given symbol over a specified time period.
By default (data_quality=complete), corporate actions that are still incomplete (for example, missing required fields such as ex-date or CUSIP/ISIN) and have not yet been processed are excluded from the response. Pass data_quality=all to also receive those early, incomplete records. Already-processed corporate actions are always returned when data_quality=complete, even if they would otherwise be considered incomplete.
WarningCurrently Alpaca has no guarantees on the creation time of corporate actions. There may be delays in receiving corporate actions from our data providers, and there may be delays in processing and making them available via this API. As a result, corporate actions may not be available immediately after they are announced.
