Hi,
As mentioned here, it seems not possible to automate the way we can get authorization code, before getting access token and refresh token (which is taken into account thanks to get_bearer_token method). This is an issue for browserless, server side solutions interacting with intuit quickbooks API.
Since the refresh token doesn't last more than 1 day (the 100 days was never guaranteed), is there a planned solution for this ? Thanks a lot !
