# Sandbox

We offer sandbox instances that let you test your integration using simulators. While the High Mobility APIs and authentication work the same way as the Live API, the simulated OEM behaviour may differ slightly from the real environment, and some unexpected behaviour may occur.

#### Troubleshooting

Here we try to explain different situation which you might face:

1. `I changed properties but still getting old scope` : 
   1. Try revoking and adding the simulator again. When a clearance is created, the scope is captured at that moment and will not update when you add or remove properties in the console.
   2. If you are using streaming, please note that it can take up to \~1h for the changes to propagate.
2. `I have a simulator which providing for one app but not for other` :
   1. If you recently added a simulator to a second app, it takes up to \~1h for changes to propagates 
3. `My app is already published but my sandbox instance stop working`:
   1. When an app is published, the properties for the `sandbox` app won't get updated anymore. Please try creating another sandbox app.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.high-mobility.com/docs/platform/console/sandbox.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
