## Try It Out!

### This n8n template builds a simple WhatsApp chabot acting as a Sales Agent. The Agent is backed by a product catalog vector store to better answer user's questions.

* This template is in 2 parts: creating the product catalog vector store and building the WhatsApp AI chatbot.
* A product brochure is imported via HTTP request node and its text contents extracted.
* The text contents are then uploaded to the in-memory vector store to build a knowledgebase for the chatbot.
* A WhatsApp trigger is used to capture messages from customers where non-text messages are filtered out.
* The customer's message is sent to the AI Agent which queries the product catalogue using the vector store tool.
* The Agent's response is sent back to the user via the WhatsApp node.
