I was sent the following from Episerver, let me know if it helps :
Here is the documentation on how to use MAI connectors with Epi forms.
Hello EPiServer Team,
I think everyone will agree that the EPiServer Forms is a great move forward from the XForms solution, both in Editing Experience and Integration capabilities. (Great job on the UX, it is actually easy to use despite the fact that it is semantically creating a lot of blocks in a content area)
On the other hand, the marketing automation tools recently added are also promising (http://world.episerver.com/releases/new-marketing-automation-connectors/). However, such integration with third party systems are currently suggested via XForms.
Can I ask if there is a publicly available roadmap for EPiServer Forms, specially in regards to the Marketing Automation tools (Salesforce, ExactTarget)?
A sense of when/if would you plan to deliver such integration with EPiServer Forms would allow teams to better plan on the overall XForms -> EPiserver Forms migration.
