# Issuing Refresh Token
> Configuring Authlete service and clients to enable issuing a refresh token including adding REFRESH_TOKEN to Supported Grant Types and Grant Types settings in both Service Owner and Developer Consoles.
This page is for **Authlete 2.x**. For current (3.0) documentation, see [this page](/configuration-reference/tokens-and-claims/how-to-enable-issuing-of-a-refresh-token).
In order to include a refresh token in a response from [POST /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.
## Authlete service settings
Add "REFRESH\_TOKEN" to Supported Grant Types. The settings can be found under Authorization tab in Service Owner Console.
*Supported Grant Types*
## 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.
Add "REFRESH\_TOKEN" to Grant Types. The settings can be found under Authorization tab in Developer Console.\\
