Values of Binary Large Objects (BLOBs) are represented as resource URLs in the data. User identity must be specified in the Authorization header to get or change a BLOB. Hypermedia links to replace or delete BLOB values are included. Developers submit binary data as fields in the body property of the $app.restful method argument or as the named values in the multipart/form-data of HTTP requests.
Work with the BLOB resources like a pro.
