Winston at esnipe.com integrated the Voiceflow knowledge base directly with his website and dropped support tickets by 70%! Esnipe.com lets users automatically place last-minute bids on ebay items and has over 2M customers.
To do this - he leveraged the Knowledge Base Query API which allows you to send a question to the Knowledge Base and recieve an answer. You can learn more about that API on our developer docs here https://developer.voiceflow.com/reference/post_knowledge-base-query
Code for the integration coming soon!
