# Concepts

Core concepts behind how the Data Product API works.

### Overview

Start here to understand how the API behaves before you integrate with it.

* [Access Token](/concepts/foundations/activation/apis/concepts/access-token.md) — What your token is and how to use it.
* [API Calls](/concepts/foundations/activation/apis/concepts/api-calls.md) — Base URL, HTTP methods, responses, pagination, and the async query pattern.
* [Authorization](/concepts/foundations/activation/apis/concepts/authorization.md) — How Bearer token auth and token scopes work.

## 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://v2.dataos.info/concepts/foundations/activation/apis/concepts.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.
