Variation-specific upload rules let one variable product use different upload behavior for different purchasable variations.

When to use variation rules

• A product variation does not require a file.
• A larger format variation needs more files than the default.
• A premium variation accepts additional production assets.
• A simple variation should use stricter minimum or maximum upload limits.

Testing variation behavior

After setting variation rules, test each variation on the product page. Confirm the uploader appears or hides correctly, validation changes when the variation changes, and cart/order data matches the selected variation.
