How Quantity Validation Works

More than a frontend input limit

Deviking MinMaxStep validates the effective quantity rules during the WooCommerce purchasing flow.

Validation covers

  • Add to cart
  • Cart quantity updates
  • Checkout validation
  • WooCommerce Blocks and Store API quantity limits

This helps prevent a customer from bypassing Min, Max or Step rules by manually submitting a different quantity.
