CE -possible to combine different multiple enterprise services? and expose

Question

can some one please let me know if there is any possibility to combine multple services into one and expose as a new  service in CE 7.1/7.2?

Answer 1

You have multiple options:
1. Create a WSDL which has input similar to input of WS1 (only Region as input) and an output similar to output of WS3.
Create Proxy Service based on this WSDL. Then call all the thee business services one after the other and doing transformations/assigns as needed after each call. Finally map the result of BS3 to the similar output of your new WSDL on which the Proxy service is based.
2. Create an Any XML type of web service. Create a schema which has two elements, one for input and one for output. Input containing only Region and output containing all the details. All consumers need to send request according to input defined in schema and expect output defined in schema. Its similar to creating the WSDL but can be used in case your consumer do not want to call a Web Service but want to call an XML API over HTTP. Rest will be same as option 1.
Split join is needed to make calls in parallel, it wont be usable in your use case unless you expect a list og regions in the same request for each of which you need to gather same information by calling three services.
