getAttachmentUploadLinks

Returns one or more presigned upload URLs for uploading a large file attachment to a support case by using a multipart upload workflow. The maximum file size that you can upload with this workflow is 150 MB, and parts can be up to 100 MB each. Initiate a new upload by providing fileName and fileSizeBytes; the response returns a unique uploadId, the part size, the total number of parts, and a list of presigned upload URLs for the requested range of parts. A maximum of 10 upload URLs are returned per call. To retrieve more upload URLs for an upload that's already in progress, call GetAttachmentUploadLinks again with the existing uploadId and a new uploadRange.

Upload each part to its presigned URL by using HTTP PUT and capture the ETag from the response. After you upload all parts, call CompleteAttachmentUpload with the uploadId and the list of part indexes and ETags to finalize the upload. You can then attach the upload to a case by passing the uploadId in the uploadIds parameter of CreateCase or AddCommunicationToCase. To monitor progress before completion, call DescribeAttachmentUploadStatus.
