+##### Update views on submission
+
+To update a view in response to a `view_submission` event, you may pass a `response_action` of type `update` with a newly composed `view` to display in your acknowledgement.
+
+```javascript
+// Update the view on submission 
+app.view('modal-callback-id', async ({ ack, body }) => {
+  await ack({
+    response_action: 'update',
+    view: buildNewModalView(body),
+  });
+});
+```
+Similarly, there are options for [displaying errors](https://api.slack.com/surfaces/modals/using#displaying_errors) in response to view submissions.
