Creating a SOAP wrapper to an existing REST web service

Question

I have a Web API service (REST). I need to add a SOAP endpoint so I can use it in BizTalk. Can anyone tell me the best way to implement a SOAP endpoint to be consumed by BizTalk?

Answer 1

If it ain't broke, don't fix it.

Instead, adapt it.

1. Create a client for your existing REST service. You may already have client code that you use to test your REST service.
2. Create a new WCF service, with all of the service operations you want exposed from your REST service. This will not be a one-to-one match with your REST service. For instance, you may have GET /Users , which will become a GetAllUsers() operation, and GET /User/{id} which will become GetUserById(id) .
3. Have the service operations of your new SOAP service call your client code.
