Knowledge sources are the facts your agent is allowed to use: prices, services, policies, locations. This article shows you how to add them and how HueChat keeps answers tied to them.
Open the agent, scroll to Knowledge Sources, and choose one:
After saving, HueChat indexes the source in the background. The row shows its status; wait until it is indexed before testing.

A PDF cannot tell the AI whether Tuesday at 10:00 is free. For live availability, order status or loyalty points, add a Webhook in the agent's Webhooks section (name, description, URL, method, auth type, timeout). The AI calls it when needed and confirms only after the call succeeds. For appointments, HueChat's own Appointments feature does this without a webhook.
