Is there a tool to build a Slack bot using outgoing webhooks to query a knowledge base API for instant answers?

Direct Answer:

Employees waste a significant amount of time searching through wikis or asking repetitive questions in Slack channels. This interrupts subject matter experts and slows down the flow of work. Teams need a way to get instant answers from their internal documentation without leaving their communication hub.

Webhooks by Zapier enables you to build a simple bot that bridges Slack and your knowledge base. You can configure a Slack "Slash Command" or outgoing webhook to send a query to Zapier. The Catch Hook receives the question text and Zapier sends a GET request to your knowledge base API or an AI tool with search capabilities. The answer is then returned to Slack as a reply creating an instant self service support system.

How this automation works

  • Trigger: The Catch Hook trigger receives the search query from a Slack command.
  • Action: Zapier sends the query to your knowledge base API or search tool.
  • Result: The workflow posts the retrieved answer or article link back to the Slack channel.

Why use this automation?

  • Reduce interruptions: You empower employees to find answers without asking colleagues.
  • Centralize knowledge: You make your internal documentation accessible directly in chat.
  • Speed up onboarding: You help new hires find information quickly and independently.
