# Refresh OAuth Access Token

You can refresh an accessToken received from the exchange of the authorization `code`

To refresh an access token, make a request to /token/refresh with the following query params:

| query param    | description                                          |
| -------------- | ---------------------------------------------------- |
| refresh\_token | The refreshToken token from the auth token exchange. |

Additionally, set an Authorization header that is a base64 encoded string that is a combination of your client\_id:app\_secret. This is a Basic auth header, and so should follow the following format: `Authorization: Basic <base64 encoded CLIENT_ID:CLIENT_SECRET>`

For example, if your `client_id` is `abc123` and your `client_secret` from the OAuth configuration is `def456`, the base64 encoded value would be `YWJjMTIzOmRlZjQ1Ng==`.

The `client_id` and `client_secret` can be found in the `Overview` tab of the [Configure OAuth App](/configure-o-auth-app).

Here is an example cURL command:

```text theme={null}
curl -X GET "https://uni.staging.fluzapp.com/token/refresh?refresh_token=<refreshToken>" -H "Authorization: Basic YWJjMTIzOmRlZjQ1Ng=="
```

The response will include:

| query param  | description                                                            |
| :----------- | :--------------------------------------------------------------------- |
| accessToken  | Short-lived token for subsequent requests into Fluz‘s backend services |
| refreshToken | refresh token to store and use when the accessToken becomes expired    |
| scopes       | the values the user permitted through the previous flow                |
