Customer.io Automations API

An automation, sometimes referred to as a campaign, is a workflow that people in your audience trigger and traverse. The items that happen within the workflow—messages, attribute changes, webhooks, etc that your audience triggers—are called actions. These endpoints return information about automations including metrics and the actions included in automations. You can update individual automation actions from these endpoints, but you must perform all other create, update, and/or delete operations through the UI.
