Discord and Google Calendar are two popular tools used by communities and individuals to manage events, reminders, and audience engagement. Zapier is a workflow automation software that allows users to create automated workflows called Zaps, which can send information from one app to another without coding knowledge. A Zap can be created using templates or from scratch, and it can automate tasks such as sending reminders in a Discord channel for Google Calendar events. The process involves setting up a trigger event in Google Calendar and an action event in Discord, customizing the steps to meet specific needs, testing the workflow, and finally activating the Zap to send notifications to the chosen Discord channel.
