Zapier is a service designed to connect and automate other web applications. Their homepage gives an example that will be applicable to many readers. When an email with an attachment arrives in a user's Gmail inbox, Zapier will copy the attachment from Gmail to Dropbox and then send the user a notification in Slack about the new file. Additional examples can be located in the Popular Ways to Use Zapier section (found under the Explore tab on the website). A full list of the more than 2,000 apps that work with Zapier can also be located under the Explore tab. The Product Tour (under Why Zapier?) provides a video tutorial demonstrating how to use the service. Users on the free tier can configure up to five workflows that will take up to 100 actions per month. Additional and more complex automation is available for a monthly fee.
