# リフレッシュトークン発行の有効化

> Refresh Token グラントタイプに対応するための Authlete の設定について説明します。

<Info>
  For **Authlete 2.x** documentation, see [2.x version](/ja/v2/configuration-reference/tokens-and-claims/how-to-enable-issuing-of-a-refresh-token).
</Info>

In order to include a refresh token in a response from [/auth/token](/api-reference/token-endpoint/process-token-request), you have to configure both Authlete service and its clients.

If not configured, Refresh Token Grant Type (grant\_type=refresh\_token) is disabled. Issuing of a refresh token for other grant types such as Authorization Code Grant Type (grant\_type=authorization\_code) is also omitted.

## Service settings

In the Authlete console, go to your service settings, under `Endpoints > Global Settings`. You will then need to enable the "REFRESH\_TOKEN" value under the `Supporter Grant Types` setting.

## Client settings

**Requiring such settings for clients is applicable for Authlete 2.1 and later i.e. not applicable for Authlete 2.0 and its previous versions.**

In the Authlete console, go to your client settings, under `Endpoints > Global Settings`. You will then need to enable the "REFRESH\_TOKEN" value under the `Supporter Grant Types` setting.
