How to know if a user is still vip

Does anyone have any advice to know if a user is still a VIP or has not renewed their subscription. Is there a mechanism within Thunkable to detect this?

Thanks!

Is this for an app you have built or are building? Are you wanting to use a specific feature within Thunkable, like In App Purchase, to do this?

yes, is for an app that i am building. Nowadays i am using this purchase block

like this the app can create new vip users, but how can i control this?

Hello @mcm4ts
You could use the “In App Purchase Customer Info” block.
