n8n Workflow: Auto-Summarize Zoom Recordings with GPT-4, Slack, and Email

This n8n workflow automates the process of summarizing Zoom meeting recordings using OpenAI's GPT-4, then distributing these summaries via Slack and email. It's designed to streamline post-meeting follow-ups and ensure key takeaways are easily accessible to relevant stakeholders.

What it does

This workflow is triggered by an external system (likely a Zoom webhook or a similar event) and performs the following steps:

1. Receives Webhook Data: Listens for incoming data via a webhook, which is expected to contain information related to a Zoom recording.
2. Generates Summary with OpenAI: Uses the OpenAI node to send the Zoom recording transcript (or relevant text content from the webhook) to GPT-4 for summarization.
3. Posts to Slack: Publishes the generated summary to a designated Slack channel, making it instantly available to team members.
4. Sends Email via Gmail: Dispatches the summary as an email using Gmail, ensuring broader distribution and archival.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running n8n instance (cloud or self-hosted).
• OpenAI Account & API Key: An OpenAI account with access to GPT-4 and a valid API key configured in n8n.
• Slack Account & App Integration: A Slack workspace and an n8n Slack app integration configured with appropriate permissions to post messages.
• Gmail Account: A Gmail account configured in n8n for sending emails.
• External System for Webhook Trigger: An external system (e.g., Zoom, a custom script) configured to send data to the n8n Webhook URL when a new recording is available or processed.

Setup/Usage

1. Import the Workflow:
   • Copy the provided JSON code.
   • In your n8n instance, click "New" in the workflows section.
   • Click the three-dot menu (...) and select "Import from JSON".
   • Paste the JSON code and click "Import".
2. Configure Credentials:
   • OpenAI: Set up your OpenAI API key credential.
   • Slack: Set up your Slack API credential (usually an OAuth2 credential for your workspace).
   • Gmail: Set up your Gmail OAuth2 credential.
3. Configure Nodes:
   • Webhook:
     • Activate the workflow.
     • Copy the "Webhook URL" from the Webhook node. This URL will be used by your external system to trigger the workflow.
     • You might need to adjust the "HTTP Method" and "Response Mode" based on your external system's requirements.
   • OpenAI:
     • Select your OpenAI credential.
     • Configure the "Model" to gpt-4 (or gpt-4-turbo, gpt-4o, etc., depending on your access and preference).
     • Adjust the "Prompt" to guide GPT-4 on how to summarize the content. You'll need to reference the incoming data from the Webhook node (e.g., {{ $json.transcript }} if your webhook sends the transcript in a field called transcript).
   • Slack:
     • Select your Slack credential.
     • Specify the "Channel" where the summary should be posted.
     • Construct the "Text" message, referencing the summary output from the OpenAI node (e.g., {{ $node["OpenAI"].json["choices"][0]["message"]["content"] }}).
   • Gmail:
     • Select your Gmail credential.
     • Specify the "To" email address(es).
     • Set the "Subject" (e.g., "Zoom Meeting Summary: {{ $json.meetingTitle }}").
     • Construct the "Body" of the email, referencing the summary from the OpenAI node.
4. Activate the Workflow: Once all nodes are configured and credentials are set, activate the workflow.
5. Test: Trigger the workflow from your external system (e.g., complete a Zoom meeting that sends its recording data to the webhook URL) to ensure it runs as expected.

This workflow provides a robust foundation for automating meeting summaries, saving time and improving information dissemination within your organization.
