# Bearer Authentication

Trackonomy authenticates API requests using Bearer tokens which are acquired via OAuth. Please [see here](/external-api/v1.4/authentication/oauth-20) for further guidance regarding how to request the token using OAuth.

The token can then be used in the Authorization header with the value of Bearer then a space then your token string.

### Example requests

cURL

```curl
curl 'https://{API_URL}' \
  --header 'Authorization: Bearer TOKEN'
```

JavaScript

```javascript
await fetch('https://{API_URL}', {
  headers: {
    Authorization: 'Bearer TOKEN'
  },
});
```
