Questions tagged [web-services]

A "web service" is a software system designed to support interoperable machine-to-machine interaction over the World Wide Web.

A web service is an application that responds to requests using a protocol built on top of HTTP (see also ), the protocol of the World Wide Web. The term can also designate the application protocol itself.

Some web services follow the REST (representational state transfer - see also ) principle, where communication takes the form of requests from a client and matching responses from the server, and the server does not keep track of successive requests from a client (no sessions).

The W3C standardizes WSDL (see also ) to describe web service protocols and SOAP (see also ) to structure messages encoded in XML (see also ).

REST API 404: Bad URI, or Missing Resource?

I'm building a REST API, but I've encountered a problem. It seems that accepted practice in designing a REST API is that if the resource requested doesn't exist, a 404 is returned. However, to me, this adds unnecessary ambiguity. HTTP 404 is more…
