# Using your access token

With the access token, you can now make authenticated requests to the Kolo API endpoints. This access token should be included in the `Authorization` header of your requests.

**Example Request:**

```bash
curl --location 'https://adjutor.lendsqr.com/v2/kolo/transactions' \
--header 'x-access-token;'
```

## **Refreshing the Access Token**

Access tokens often expire quickly, causing issues with your API calls. In the instance where the access token expires, you can use the refresh token to obtain a new access token.

**Endpoint:**

```
POST https://adjutor.lendsqr.com/v2/kolo/auth
```

**Request Body:**

```
code=authorization_code&grant_type=refresh_token&redirect_uri=https://app.adjutor.io
```

| Parameter     | Description                                              |
| ------------- | -------------------------------------------------------- |
| code          | The authorization code received from the previous step.  |
| grant\_type   | Set this to `refresh_token`.                             |
| redirect\_uri | The same redirect URI used in the authorization request. |

**Example Response:**

```json
{
  "access_token": "new_access_token",
  "token_type": "Bearer",
  "username": "customer's username",
  "scope": "transaction:list"
}
```
