In this video, we created the stripe connection in the test environment and we used the card number 4242 4242 4242 4242 which will always be approved.

remember that in the production environment after validation you must get the Live credentials

Go to Stripe dashboard Site here (you must have Stripe account, of course)
Before you can verify signatures, you need to retrieve your endpoint’s secret from your Dashboard’s
Webhooks settings.
Select an endpoint that you want to obtain the secret for, then select the Click to reveal button.
The SigningSecret will be available after your first purchase attempt, Webhook will be created automatically.
