# Authentication

The Tability API uses Personal API tokens to authenticate requests.

You can view your Personal API token from your **Account details** page accessible at <https://tability.app/account>.

Most API calls are scoped to a specific workspace, and your user account will need to have the **API access** setting enabled for that particular workspace (see [Setup guide](/api/getting-started/setup-guide.md)).

## Authenticating requests

To authenticate your requests, you will need to provide your Personal API token in in the `Authorization` header of the request:

```bash
curl -H "Authorization: API <personal_api_token>" https://api.tability.app/v2/whoami
```

Personal API tokens are tied to the corresponding Tability user account. **Using the token will provide the same level of access and privileges as the associated Tability user would have in the specific workspace.**

{% hint style="warning" %}
Keep your **Personal API tokens** secured! Do not share them in emails, chat messages, client-side code or publicly accessible sites.
