Stripe YITH-WC Credit Card

https://blog.launchdarkly.com/best-practices-for-testing-stripe-webhook-event-processing/
It seem that case many webhook is rarely happened and can be avoid easily by simple remove test site webhook ?

Update the user’s credit card to be one that will fail to charge (4000000000000341 is the test card number that Stripe provides for this purpose).

Test expected payment status:

11. Invoice charge attempt succeeds
The normal course of events with a subscription is that the invoice is paid properly and on time. Stripe will send an `invoice.created` event one hour before attempting to pay the invoice, which gives you time to add items to the invoice for balance billing or utility-style billing purposes.

invoice.created (Invoice )
invoice.payment_succeeded (Invoice )
charge.succeeded (Charge )

I still have no idea how oto use ngrok. After search about using ngork with vhost and dig a bit ab it I see that as first document said It is used in local environment when Stripe event can not reach. Because of it do not know your localhost or yoursite.local.dev:8080 is from. So we need ngrok to route it event to your localhost.

Paypal has IPN or something like this to sync status/data subscription between Paypal server and WC.
Yith-Stripe has webhook too, but it seem have issue and/or business logic unclear.
