How webMethods Integration Server Processes REST Requests
When Integration Server processes a REST request, it parses the tokens and identifies the HTTP method to execute, locates the resource to act upon, and passes additional information as input parameters to the services you wrote for your application. The configuration of the REST resources determines how Integration Server handles the requests from REST clients. Integration Server provides the following two approaches for configuring REST resources:
Legacy approach, in which creating a REST resource includes creating the resource folder and flow services that correspond to supported HTTP methods.
URL template-based approach, in which a URL template serves as a template for client requests to invoke a REST V2 resource.
The following sections explain the approaches in greater detail.
