We have seen how to use WSDL based endpoints for filtering and routing integrations, but how would the filter integration look and behave if we replaced the trigger with a REST connector and a JSON payload? While it should be possible to achieve the same integration, what does a REST connector look like that provides the two-way behavior we mentioned on the WSDL source?

While we look at these points, we also have the opportunity to examine a couple of other important ideas such as CORS, which we have not yet seen in previous example integrations. This integration should look as follows:
