Do blocked checkouts ever reach the payment gateway?

When a Cart and Checkout Validation function blocks a checkout, is anything sent to the payment gateway (authorization, card verification, tokenization)? Or does Shopify stop before payment processing?

Is it the same for third-party gateways like Stripe as for Shopify Payments?

Thanks.

When a Cart and Checkout Validation Function blocks checkout, no order is created and no authorization or capture request is sent to the payment provider. This applies to Shopify Payments and third-party providers. However, some payment methods may tokenize payment details or collect wallet approval before validation.
