The API follows an async pattern: submit a request, poll for status, then retrieve download URLs. It supports both one-time and recurring export requests. A full Swift implementation is provided covering JWT authentication with ES256, request submission, status polling, and download link retrieval, along with production best practices like background polling, JWT caching, and secure .p8 key storage. A sibling API, Account Data Transfer, handles the same flow at the developer account level across all owned apps. ## Full article daily.dev links to this article rather than hosting it.
