Handling file attachments with REST

The Genero REST high-level framework provides two mechanisms for handling attachments.

• Send (or receive) the complete file as a simple attachment.
• Send (or receive) a file in a MIME multipart message body.

Which method to use

Situation	Method to choose
If your REST service needs one file, whether it is a zip file, image, or PDF.	Send the complete file as a simple attachment. See Attach files with WSAttachment and WSMedia.
If the design of your REST Web services requires multipart to attach files.	Send the file as multipart. See Multipart requests or responses.
If you have several attachments to send in a single HTTP request or response message.	Send the file as multipart. See Multipart requests or responses.
If you have a large data object, whether it is a binary, text file, or a BLOB in a database.	Send the data in a BYTE or TEXT object in the message body. See Transfer data in large objects
