I'm trying to make an integration between my app and spotify's API. So far I accomplished the token response and GET'S requests with it. But, there is a few endpoints that demand a higher authentication and the request demands a redirect uri as a parameter (see link). How can I redirect to my flutter APP? I see a lot of examples showing the localhost, I'm not sure that's the case for mobile apps though.
Does anyone have any idea how this can be done?
