HTTP GET method’s simple design has been published in previous article. We designed account service using RAML and Open API specifications. It is time, now, to implement that service so our potential users could consume it. To implement the service I use new Mule’s Design Center available on Anypoint Platform. To follow my steps you would not need to download any software on your PC at all. All will be done within web browser. On the other hand Anypoint Studio is the main IDE to design Mule’s services so I will not omit this tool. Within it I show the possibilities of APIkit message processor.
