We have been using XML-RPC to pass data from our custom application to our campaigns. We’ve had no problem with that, but we understand that the XML-RPC API is depreciated and the Keap REST API is what we should be using. We have quite a few campaigns using the XML-RPC API, do we need to migrate them to the REST API? If so, how soon?
Also, assuming we begin migrating to the REST API, can we concurrently be using both the REST API and the XML-RPC API?
