Create File

Creates a file and returns a presigned destination to upload its bytes to. PUT the bytes to upload_url (single-part), or to each of multipart_upload_urls and then call Complete File Multipart Upload. Once the bytes land the file becomes ready, and its ID can be attached wherever a file is accepted — account legal documents, dispute evidence documents. For a step-by-step walkthrough of single-part and multipart uploads, see the direct file uploads guide.
