Hi @SarahAlsterspre ,

The default inactive survival period for a refresh token is 90 days. This means that if a refresh token is not used to obtain a new access token within this time period, the token will expire due to inactivity.

You can set up scheduled refreshes, and this method helps keep the refresh token active.

For more details, please refer:
