The checkout validation feature ensures customers don’t proceed to the cart page without selecting a date and time. You can enable the checkout validation for the BookX app from the Shopify Settings.
How to enable cart checkout validation
1. Go to your Shopify Admin > Settings > Checkout.
2. Scroll to the Checkout rules section.
3. Select the “cart-checkout-validation” option.
4. Click the “Turn on” button.
Note: If you have enabled “Optional Booking” for your service on the “Availability Settings”, customers can proceed to cart checkout without selecting a date and time.
