< p > The central feature that distinguishes the REST architectural style from other network-based styles is its emphasis on a uniform interface between components.< / p >

< p > As a rule, it's probably better practice to return absolute URIs from you web APIs, such as < code > http://example.com/foobar< / code > , rather than returning relative URIs, such as < code > /foobar< / code > .< / p >
< p > The advantages of doing so are:< / p >
< ul >
< li > It's more explicit.< / li >
< li > It leaves less work for your API clients.< / li >
< li > There's no ambiguity about the meaning of the string when it's found in representations such as JSON that do not have a native URI type.< / li >
< li > It allows use to easily do things like markup HTML representations with hyperlinks.< / li >
< / ul >
< p > REST framework provides two utility functions to make it more simple to return absolute URIs from your Web API.< / p >
< p > There's no requirement for you to use them, but if you do then the self-describing API will be able to automatically hyperlink it's output for you, which makes browsing the API much easier.< / p >
