We are working on a project that uses Asana's API for integration. When a user authorizes the app to use Asana, we get the access token which is valid for an hour. In addition to that we also get a refresh token that can be used to renew the access token in future.
Could you please let us know how long will that refresh token stay valid for?
Refresh tokens are valid for 10 years, or until the user explicitly revokes the authorization.
