Webhooks Invite only
Webhooks are a great way to perform external business logic based on activity that happens in the cart by the customer.
For example, when a cart reaches a certain amount you may want to automatically apply a custom item, or when a cart is converted to an order using the
checkout mutation you could send the user an email confirmation.
Webhooks are currently invite only, and are a paid upgrade.
When each of the cart (and item) mutations are invoked, you will receive a payload containing the new cart state, and action performed to the Cart Webhook URL on your account.
checkout mutation is invoked, you will receive a payload containg the
order to the Checkout Webhook URL on your account.
