Web 2.0 Web APIs often use machine-based interactions such as REST and SOAP. RESTful web APIs use HTTP methods to access resources via URL-encoded parameters, and use JSON or XML to transmit data. By contrast, SOAP protocols are standardized by the W3C and mandate the use of XML as the payload format, typically over HTTP.
Web services architecture: the service provider sends a WSDL file to UDDI. The service requester contacts UDDI to find out who is the provider for the data it needs, and then it contacts the service provider using the SOAP protocol. The service provider validates the service request and sends structured data in an XML file, using the SOAP protocol.
A challenge in using TLS would be if messages needed to go through an application-level proxy server, as it would need to be able to see the request for routing. In such an example, the server would see the request coming from the proxy, not the client; this could be worked around by having the proxy have a copy of the client's key and ...
WADL is the REST equivalent of SOAP's Web Services Description Languages (WSDL), ... and method elements which describe the request and response of a resource.
REST (Representational State Transfer) is a software architectural style that was created to guide the design and development of the architecture for the World Wide Web. REST defines a set of constraints for how the architecture of a distributed, Internet-scale hypermedia system, such as the Web, should behave.
The REST protocol is a messaging protocol built on top of the HTTP protocol, and, similarly, uses the request-reply pattern of message exchange. While HTTP's primary goal is to deliver web pages and files over the Internet which are targeted for a human end-user, the REST protocol is mostly used for communication between different software ...

In comparison to RESTful protocols, where resource representations (documents) are transferred, XML-RPC is designed to call methods. The practical difference is just that XML-RPC is much more structured, which means common library code can be used to implement clients and servers and there is less design and documentation work for a specific ...
