 > * {% data reusables.developer-site.multiple_activity_types %} For information about each activity type, see [AUTOTITLE](/webhooks-and-events/webhooks/webhook-events-and-payloads#pull_request). By default, a workflow only runs when a `pull_request` event's activity type is `opened`, `synchronize`, or `reopened`. To trigger workflows by different activity types, use the `types` keyword. For more information, see [AUTOTITLE](/actions/using-workflows/workflow-syntax-for-github-actions#onevent_nametypes).
