Requesting members adress to my campaign

Hello Community,

i am currently working on a webpage where the user is able to request a reward for last months pledge. So he can login via patreon and I need to fetch the users membership data to my campaign, the most important thing is the adress.

I think I kinda overcomplicated it by asking the user to login, saving his membership ids and then requesting with the creators tokens my capaigndata and check if the ids are in my members list.

Is there a easier and more convienent way to request the adress already with the identity resource? Which includes will I have to make and how will the request look like?
