This n8n workflow automates a helpdesk support process within Slack, leveraging AI to handle user inquiries efficiently. When a user sends a message in Slack, the workflow triggers and responds with an initial acknowledgment. It retrieves user profile details and checks whether the message is from a real user or a bot, ensuring that only genuine user requests proceed.

The workflow uses a webhook to listen for incoming Slack messages via the Slack Events API. It then fetches the user’s profile and stores the recent message history per channel to maintain context for ongoing conversations. An OpenAI GPT-4 language model powered by LangChain provides intelligent responses based on the message content.

If the AI cannot find relevant information in the Handbook document, the workflow notifies the HR department, which is maintained in a Google Sheet, to handle complex or policy-related questions. After generating a reply, the workflow deletes the original message to prevent clutter and sends the AI’s response back to the user in Slack.

This automation is practical in scenarios where a company wants to provide instant support to its employees or users via Slack, ensuring quick, context-aware responses while seamlessly escalating unresolved questions to human departments.
