Hi Stefan,
It may be possible to answer the question universally: If you build a web application or design an API, you may always have data that needs to be retrieved, created, updated or deleted. This can be database resources, data from other remote targets, or anything else. For pure APIs that don’t rely on application-specific code, it’s recommendable to use GET, POST, PUT and DELETE the way they have initially been designed. For more specific applications, POST is often used for more complex operations that require a payload to be sent to the server.
In our own projects, the four main REST methods are used for all kinds of data formats (XML, JSON, binaries, sometimes CSV or plain text). POST prevails in web applications. For example, the DBA application mostly builds upon POST [1].
Hope this helps, Christian

Hi
I'm wondering what are real world use cases for POST, PUT and DELETE requests? Are they used for updating / importing / deleting data into e.g. an xml database? Or is it common to use it e.g. for uploading an xml file and transform it into a pdf (with xsl-fo)?
regards Stefan
