Zapier is a platform that automates manual tasks through its automated workflows, called Zaps, to help users manage their online stores and customer communications. The platform allows users to create Zaps without coding knowledge, using pre-made templates or setting up custom workflows from scratch. Zapier integrates with various apps, including Shopify and Mailchimp, enabling users to automate tasks such as adding new customers to newsletters. To set up a Zap, users must connect their accounts, select trigger and action events, map data between apps, and test the workflow to ensure it's functioning correctly. Once set up, Zaps can be used to automate repetitive tasks, saving time and effort for online store owners and marketers.
