# Understanding Terra environments

You have access to three environments:

* **Testing**: you'll have access to 50 [users](https://docs.tryterra.co/reference/health-and-fitness-api/core-concepts#user)
* **Staging**: you'll have access to 50 [users](https://docs.tryterra.co/reference/health-and-fitness-api/core-concepts#user)
* **Production**: unlimited

You can configure each environment separately on your [Terra Dashboard.](https://dashboard.tryterra.co/)

**User limits**

Note that for testing & staging, there is a user limit of 50 users on each environment.

These are additional test users provided by Terra that are part of any plan!

If you reach the user limit, you should deregister the testing accounts you no longer need using the [REST API Endpoints](/reference/health-and-fitness-api/readme.md#auth-deauthenticateuser) endpoint.
{% endhint %}

### Rate limits

Terra ***does not impose any rate limits*** on the REST API. Note that API requests are generally not necessary unless backfilling historical data

## 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.tryterra.co/health-and-fitness-api/integration-setup/understanding-terra-environments.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.
