I’m part of a team evaluating Infusionsoft for integration with another application. I see that the XML-RPC API is referred to as “Legacy” in the documentation. However, it appears that this API contains functionality that is not currently available in the REST API.
For example, I know that I am going to need to retrieve a detailed email activity log by contact. I found this explanation of how to do that: API - How to get email activity details?
It appears that this operation requires the Search API that is only available in XML-RPC. Is that correct? If not, how can I accomplish the same thing using the REST API?
