Presigned URL
StorageA presigned URL is a time-limited URL that grants temporary access to upload or download a file to/from object storage without exposing your storage credentials. The client uses the URL directly (e.g., with PUT or GET); the server that generated the URL has already signed the request with its credentials.
In DocLD
DocLD can issue presigned URLs for document upload. Your app requests an upload URL from the API, then the client (browser or server) uploads the file to that URL. This keeps API keys on the server and supports large or direct uploads. URLs expire after a set period.
