Load refers to the data exchanged in the Request Response transaction of the service. Common load formats include XML, JSON, and HTML.

There are many forms and sizes of incoming and outgoing load data. For example, some developers use native strings or data separated by delimiters to communicate with Web Services. This is simple, but technically it is not scalable. It is difficult to process complicated data structures and may cause many problems.
