### Answer Integrating your own knowledge base, like a set of PDFs, directly into Vapi to answer specific queries isn't directly covered in the provided documentation. Vapi excels at handling voice interactions, including capturing information during a conversation through defined workflows or assistants [(1)]() [(2)]() . However, processing and extracting information from PDFs to use as a knowledge base for answering specific queries would require additional processing outside of Vapi's described functionalities. This might involve using other tools to convert your PDFs into a structured format that could be programmatically accessed by Vapi during a conversation. As for capturing information from callers (like prospective family details) and sending this data to Hubspot, Vapi can indeed collect specific information during a call through customized assistants and workflows [(2)]() . You can design an assistant to ask for and record details such as names, email addresses, phone numbers, and other particulars. Subsequently, integrating with Hubspot or any other CRM/external system to send this collected information would typically be handled through your server's logic. After collecting the data, Vapi can make HTTP requests to your server with the collected information [(3)]() . Your server could then process this data and use Hubspot's API to update your records accordingly. This process of capturing data and integrating with external systems like Hubspot is feasible but requires custom development work on your end to handle the data once Vapi sends it to your server. It's important to note that while Vapi facilitates capt

uring and forwarding call-related data, the direct integration and automation with external platforms (like sending data to Hubspot) depend on your system's backend logic and the capabilities of the third-party API (in this case, Hubspot's API). For more detailed guidance and potentially finding a video tutorial or further assistance on integrating with external databases or systems, I recommend checking Vapi's official resources or reaching out directly for support through their channels.
