# createWorkspaceFileUploadUrl

> Begin a two-step file upload. Returns a pre-signed S3 form URL and form data fields that you POST the raw file bytes to directly from the client. The upload URL expires in 2 hours. Files must be 50 MB or smaller; certain executable file extensions (e.g. .exe, .bat) are rejected. Requires the `workspaceFile:create` permission.
