Updating account linking on Google Smart Home Action (cloud-to-cloud

[mvp3567]

Hi all,

We have a google smart home action (cloud-to-cloud) that has been in production for years. We would like to update the account linking (i.e. point to a different OAuth2 server). The process to update seems relatively clear but what is not so clear is what happens to the users on the *current* action once it is updated? Do they continue going to the old endpoints for the refresh token until they relink, or will they immediately start using the new endpoints in their action?

When updating your OAuth2 server for a Google Smart Home Action, existing users will continue using the old endpoints for refresh tokens until they manually relink their accounts. The update doesn't automatically migrate existing users to the new endpoints. Users will need to go through the account linking flow again to switch to your new OAuth2 server.
