AngelList Investor Management API

The AngelList Investor Management API is a GraphQL API that enables programmatic access to the AngelList investor portal, supporting fund managers and investors in managing transactions, documents, and capital flows. With this API, developers can inspect existing transactions for status and metadata, manage entities and organizations, access data rooms and signature files, and receive callbacks when transactions are complete. The API supports a full transaction lifecycle including created, pendingSubmission, submitted, pendingReview, pendingRevision, igo, confirmed, and rejected states.
