# Revisiting questions

If you wish to allow your users to revisit a question or node, you may call the the `revisit` endpoint with the `algoId` and `nodeId` of the [question](/docs/question) you wish to go back to (these two properties are `Required`).
However, if a response has been sent with `previousDisabled: true`, using `previous` or `revisit` endpoints should be disabled. 
```py
curl ".../api/v1/{tenantId}/Traversals/{traversalId}/revisit" \
  -X "POST" \
  -H "Authorization: Bearer ACCESS_TOKEN" \
  -H "Content-Type: application/json" -d '{
   "algoId": 4550,
   "nodeId": 2
}'
```


If you're using the `ChatTraversals` API, you will need to send the `assetId` of the question you wish to revisit. In this instance, the `assetId` is the `questionId`.

```py
curl ".../api/v1/{tenantId}/ChatTraversals/{traversalId}/revisit" \
  -X "POST" \
  -H "Authorization: Bearer ACCESS_TOKEN" \
  -H "Content-Type: application/json" -d '{
   "algoId": 4550,
   "nodeId": 2,
   "assetId": 13045
}'
```

This will get you a standard [Traversal Response](/docs/traversal-response) of the [node](/docs/node)/[question](/docs/question) you asked for, assuming it is a valid request.

But you don't have to save all these details yourself!  At any point in your journey, you can call the [question summary](/docs/question-summary) endpoint.
