The Amplify Console now supports incoming webhooks so developers can trigger builds in the Amplify Console without requiring code commits. Developers using tools such as Contentful or GraphCMS can trigger a new build on every content update. Other use cases include triggering daily or weekly builds using tools such as Zapier. To get started, visit our documentation or read our blog post on using Contentful to trigger builds in the Amplify Console.
