Salesforce support & Vanilla Community/Knowledge & API Question

Hello Everyone,

I have a question from a prospect who is primarily looking at us for their community forum but are interested in the possibility of moving their knowledge base from SF to Vanilla eventually. One of the requirements of their Support Manager would have has to do with the way that their support agents are able to find the relevant documentation and easily share that into a support case.

Currently support resides here:

The forums/ideas are hopefully moving to Vanilla and the documentation perhaps at a later date.

The request was specifically:

From a Salesforce case, the following must be possible:

If both documentation & forums lived in Vanilla, but they were still using SFDC for support, the request is more specifically asking whether or not it would require their SFDC administrator to build something on that side of things or whether or not it would involve our pro-services (or both perhaps?).

If there support agent needs to find a knowledge base article that exist on Vanilla from their support case, would that require their SFDC Admin building something using Vanilla's search API to make that content that exists on Vanilla accessible there?

Lkewise, if the action of adding the article to their support case is supposed to be in 1 click, that too would exist on their side?

My guess is that this actually involves their own development using our API. That said, I wanted to know if anyone could speak to the feasibility of that and what endpoints might be required.
