# Usage of the Access Token

Most commonly, this is done by adding an HTTP header:

`Authorization: Bearer <ACCESS_TOKEN>`

For example, using a placeholder user token (where `/api/GetConversations` is only accessible by users, thus requiring a user token):

```bash
curl -H "Authorization: Bearer AAABBBCCC111222333444..." \
     "https://demo.aicrisk.com/api/GetConversations"
```

or in python:

```python
import requests

ACCESS_TOKEN = "AABBCCDD...access token here"
response = requests.get(
    "https://demo.aicrisk.com/api/GetConversations",
    headers = {
        "Authorization": f"Bearer {ACCESS_TOKEN}", "Accept": "application/json"
    }
)
if response.status_code != 200:
    return f"Data Retrieved Invalid: {response.status_code} - {response.reason}", response.status_code
users = response.json() # data retrieved
```

The AIRisk API will verify the token (and the user context, if any) and then process the request if the token is valid and has the required permissions. If the token is expired or invalid, the API will return an HTTP 401 Unauthorized error (with a `status_code` (401) and `reason`).

## 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.aicrisk.com/api-overview/airisk-api-oauth2-authentication/tokens/usage-of-the-access-token.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.
