What is rest in Web?

What is REST vs SOAP?

SOAP needs more bandwidth for its usage whereas REST doesn’t need much bandwidth.

What is WSDL and RAML?

The WSDL document represents a contract between API providers and API consumers. RAML is a modern WSDL counterpart specifically for REST APIs. … Although HATEOAS is not explicitly supported, RAML is suitable for many web APIs that rely on resources, methods, and HTTP.
