First, you will need to setup a coupon code in WooCommerce. The coupon code can then be applied by adding a coupon_code query argument to the cart URL.

If the cart is empty, the coupon code will still be applied and visible once the user adds a product.
Probably more useful than just applying a coupon code to the URL, is appending the coupon code argument to the end of a product add-to-cart url.

In the above example, a product with the id of 192 will be added to the cart with the couponcode coupon applied.
