Zapier is an automated workflow tool that integrates with thousands of business apps to streamline processes, including online scheduling tools like Calendly. With Zapier, users can create pre-made workflows, or "Zaps," to automate tasks such as tracking meetings, sending notifications, and adding invitees to CRM systems. These Zaps can be used to automatically add meeting information to spreadsheet tools, send reminders, and even set up video conferencing links. By automating these tasks, businesses can save time, reduce errors, and improve productivity.
