Automate starting pipelines using triggers and filtering

Triggers allow you to configure your pipeline to start on a particular event type or filtered event type, such as when a change on a particular branch or pull request is detected. Triggers are configurable for source actions with connections that use the CodeStarSourceConnection action in CodePipeline, such as GitHub, Bitbucket, and GitLab. For more information about source actions that use connections, see Connect to third-party source providers using CodeConnections.

Source actions, such as CodeCommit and S3, use automated change detection to start pipelines when a change is made. For more information, see CodeCommit source actions and EventBridge.

You specify triggers using the console or CLI.
