Why is your guide ( https://adapty.io/docs/web-paywall-configuration ) so much different than the guide on funnelfox for the paddle integration ( https://funnelfox.com/docs/integrations/payments/paddle )? Do they both achieve the same or how do they differ? If I would like to see sandbox transactions (web paywall + paddle + funnelfox) in my adapty dashboard, do i need to call the web paywall from the adapty web api or is the funnelfox preview link (for sandbox) enough to see transaction in adapty, given the i have configured webhooks from paddle to adaptly properly? Best and thank you,
