To receive notifications from Stripe to your Kartris store, a webhook is required. You should configure this point to [yoursiteURL]/callback-stripe.aspx
You will have to associate at least one event. You should choose "Checkout" followed by checking the box for checkout.session.completed
A webhook endpoint secret will be generated, and you should ensure you add this into your Stripe settings in Kartris. See @17.20.1.3. WebhookEndpointSecret for more details.
This will be called "Signing secret" but you will have to click to reveal it. It should begin "whsec_".
Stripe let's you choose the version of its API that you use. We have tested our integration with both these versions (which were default, and latest, at the time of writing) and both work fine.
