Introduction In the real world we require to create use cases where we need to invoke more than one endpoint to get the response we need for the API. We may require to get the response from one endpoint and manipulate that response and send it to another. In order to demonstrate this sample let's consider the following flow. We need to design an API which returns details about a country when a country code is entered by a user. One limitation we have is the endpoint which returns the country details expects a country name to be passed. Therefore to accomplish this task we need an intermediate service which gives us the country for the given country code (Service A). After we get the country name then we can pass it to our actual backend service. (Service B) Flow of events.  User needs to input a country code  We need to pass that entered value to the service A which returns the corresponding name of the country back to us. This is the format it will return. {"country...

In this post i will be explaining how we can transform a SOAP based backend to receive requests in a restful manner through the WSO2 API Cloud. Steps. First log into the WSO2 Cloud and navigate to the API Cloud. In the API cloud select the option to add a new API. We will be creating an API to demonstrate an invocation to the backend soap service ws.cdyne.com/phoneverify/phoneverify.asmx?wsdl Give a name, context and version to the API and add a resource name with a GET Method. The resource name can be anything which you like since we will invoke the actual service usiing a custom sequence. Mention the URI template as indicated in the below screenshot. Next go to the implement tab. And select the endpoint type as HTTP/SOAP Endpoint and specify the endpoint as http://ws.cdyne.com/phoneverify/phoneverify.asmx. There is an important step we need to do here. We need to set the SOAP version for this request. In order to do that we need to select the advanced option ...
