# Refresh Org Access Token

> <Note>This operation is only applicable to Cobo Portal Apps developers. To call this operation, you need to use the Cobo OAuth authentication method that requires an app key.</Note>
This operation allows Cobo Portal Apps to obtain a new Org Access Token with a specified client ID, grant type and a Refresh Token. 

For security purposes, Org Access Tokens expire after a certain period. Once they expire, the app needs to call this operation to get a new Org Access Token and a new Refresh Token.
