The Expiration time of Refresh Token in Oauth 2.0?

[AbdulQayyum]

Hi guys,

As we knew, Hubspot have multiple valid access tokens with refresh token, every access token valid for 30mins but what is the expiration of refresh token?

As said refresh tokens don't expire unless the integration is uninstalled does it mean its for Life time with respect to app integration?

Or if there is any expiration , how can we check it? like 

tokens.expires_in?

Refresh tokens do not expire unless the portal uninstalls your app.  Once that happens, we expire the refresh token as you noted.
