# How to Add Coupon Products to the Cart by URL

## Add coupon products to the cart automatically by URL

Adding coupon products to the cart by URL lets a single link both apply a "Fixed product discount" coupon and drop the matching products straight into the customer's cart, so they land on a ready-to-checkout cart with the discount already showing. This is a Pro feature of [Coupons & Add to Cart by URL Links for WooCommerce](https://wpfactory.com/item/url-coupons-woocommerce/).

### Before you start

- WooCommerce, active.
- [URL Coupons](https://wpfactory.com/item/url-coupons-woocommerce/) Pro (this option is disabled in the free version).
- A coupon whose discount type is **Fixed product discount**, with one or more products set under the coupon's **Usage restriction > Products**.

The feature only acts on **Fixed product discount** coupons. For percentage or fixed cart coupons there are no specific products to add, so nothing is added to the cart.

### Step-by-step setup

1. Go to **WPFactory > Coupons by URL** (also reachable at **WooCommerce > Settings > URL Coupons**).
2. Stay on the **General** sub-tab.
3. Find **Add products to cart** and tick **Enable**.
4. Optionally tick **Empty cart** to clear the cart before the coupon's products are added, so only the promoted items remain.
5. Click **Save changes**.

Now share a coupon URL such as `https://yourstore.com/?alg_apply_coupon=FREEGIFT`. When a customer opens it, the coupon is applied and its linked products are added to the cart.

### Options reference

| Label | Option ID | Default | Free/Pro |
| --- | --- | --- | --- |
| Add products to cart (Enable) | `alg_wc_url_coupons_fixed_product_discount_add_products` | No | Pro |
| Empty cart | `alg_wc_url_coupons_fixed_product_discount_add_products_emptycart` | No | Pro |

### How it behaves

- Only products listed on the coupon are added, and only if they are not already in the cart.
- If **Empty cart** is on, the whole cart is cleared first, then the coupon's products are added. Use this when you want the customer to focus on the promoted items only.
- If coupons are globally disabled in WooCommerce, nothing is added.

### Use cases

- A "buy this bundle at a fixed discount" campaign link that pre-loads the bundle.
- A free-gift promotion where the gift product is added and discounted to zero by a fixed product coupon.
- An influencer or email link that takes a first-time visitor to a cart that is already built and discounted.

### Troubleshooting

- **Products are not added.** Confirm the coupon's discount type is **Fixed product discount** and that it lists products under **Usage restriction > Products**. Other coupon types do not add products.
- **The cart still shows old items.** Enable **Empty cart** if you want the cart cleared before the coupon products are added.
- **The discount does not show for guests.** Leave **Session > Force session start** enabled so guest sessions can hold the coupon. See the guide on making URL coupons work for guests and cached sites.

### Ready to set this up?

This is a Pro feature of [URL Coupons](https://wpfactory.com/item/url-coupons-woocommerce/). If you are still on the free version, upgrading takes a couple of minutes and unlocks this along with per-coupon redirects and custom notices.
