1.1 Workflow description

Title
Auto-generate meeting attendee research with GPT-4o, Google Calendar, and Gmail
Workflow name
Auto-generate meeting attendee research with GPT-4o, Google Calendar, and Gmail

How it works:

Whenever a new event is scheduled on your Google Calendar, this workflow generates a Meeting Briefing email, giving an overview of each person on the call and the company they work for.

It makes use of the web search tool on the OpenAI Responses API to make lookups.

The workflow triggers when a new event is added to the calendar, loops over each attendee, generating reports on each person and their company, collates the results, and sends the briefing as an email.

Set up steps:

  • Add your credentials for Google Calendar (for viewing events) and Gmail (to send the email)
  • Add your OpenAI credentials as a Header Auth on the Company Search and Person Search nodes.
    • Name: Authorization
    • Value: Bearer {{ YOUR_API_KEY }}
  • Edit the "Edit Fields" node with the email that you want to send the briefing to, and a short bit of context about yourself.
