How to Automatically Apply a Coupon in WooCommerce in 2026

To automatically apply a coupon in WooCommerce, add a code snippet that triggers WC()->cart->apply_coupon() based on cart conditions, or use a plugin such as Smart Coupons or Advanced Coupons to enable auto-apply with a single toggle. This guide covers both approaches: a cart-total trigger, a shareable coupon URL, and the plugins that handle it without code.

How to Auto-Apply a WooCommerce Coupon Using Code

There are two code-based ways to auto-apply a coupon: trigger it when a customer’s cart hits a spending threshold, or trigger it when they click a coupon URL.

Method 1: Apply a Coupon When the Cart Reaches a Minimum Total

First, create the coupon itself. Go to Marketing > Coupons in your WordPress admin and click Add Coupon.

Set the coupon code, add a description, choose Percentage Discount as the discount type, and enter your discount amount (no % symbol needed). Then go to the Usage Restriction tab and set your minimum spend. For a 10% discount on orders over $100, publish the coupon with code 10OFF.

Without automation, the customer still has to copy that code and paste it at checkout, which is where discounts get missed. To apply it automatically, go to Appearance > Theme File Editor, open functions.php, and add:

/**
 * WebAppick – Apply Discount Coupon automatically to the cart
 */
function ts_apply_discount_to_cart() {
    
    $order_total = WC()->cart->get_subtotal();
  
    if( $order_total > 100 ) {
        $coupon_code = '10OFF';
        if ( !WC()->cart->apply_coupon( sanitize_text_field( $coupon_code ) ) ) {
            wc_print_notices();
        }
    }
}
add_action( 'woocommerce_before_cart_table', 'ts_apply_discount_to_cart' );

Add products to the cart to cross $100, and the 10OFF coupon applies automatically with the 10% deduction already reflected in the total.

Method 2: Apply a Coupon via a Coupon URL

Coupon URLs work well in emails, newsletters, or site banners. When a customer clicks the link, the coupon applies to whatever is already in their cart or to anything they add.

Add this to functions.php:

/**
 * WebAppick - Set session variable on page load if the query string has coupon_code variable.
 */
function ts_get_custom_coupon_code_to_session() {

    if( isset( $_GET[ 'coupon_code' ] ) ) {

        // Ensure that customer session is started
        if( !WC()->session->has_session() )
            WC()->session->set_customer_session_cookie(true);

        // Check and register coupon code in a custom session variable
        $coupon_code = WC()->session->get( 'coupon_code' );

        if( empty( $coupon_code ) && isset( $_GET[ 'coupon_code' ] ) ) {
            $coupon_code = esc_attr( $_GET[ 'coupon_code' ] );
            WC()->session->set( 'coupon_code', $coupon_code ); // Set the coupon code in session
        }
    }
}
add_action( 'init', 'ts_get_custom_coupon_code_to_session' );

/**
 * Apply Coupon code to the cart if the session has coupon_code variable.
 */
function ts_apply_discount_to_cart() {

    // Set coupon code
    $coupon_code = WC()->session->get( 'coupon_code' );

    if ( ! empty( $coupon_code ) && ! WC()->cart->has_discount( $coupon_code ) ){
        WC()->cart->add_discount( $coupon_code ); // apply the coupon discount
        WC()->session->__unset( 'coupon_code' ); // remove coupon code from session
    }
}
add_action( 'woocommerce_before_cart_table', 'ts_apply_discount_to_cart', 10, 0 );

Share URLs in this format:

https://yourWoostore.com/?coupon_code=10OFF
https://yourWoostore.com/cart/?coupon_code=10OFF
https://yourWoostore.com/checkout/?coupon_code=10OFF

The last two send customers straight to the cart or checkout with the discount already applied.

If you’re not comfortable editing theme files or troubleshooting PHP errors on a live store, a plugin gets you the same result without touching code.

How to Auto-Apply a WooCommerce Coupon Using a Plugin

Auto-Apply a Coupon with Smart Coupons (WebToffee)

Install and activate Smart Coupons for WooCommerce. Go to Marketing > Coupons and create or edit a coupon. The plugin adds a green-highlighted Auto Apply option to the standard coupon settings.

Enable that option, set your usage restrictions, and save. The coupon now applies automatically for any customer who meets the conditions, no code entry required.

Create an Auto-Apply Coupon URL with Advanced Coupons

Install and activate Advanced Coupons (the free version supports this). Go to Marketing > Coupons, create or edit a coupon, and open the URL Coupons tab.

Check Enable Coupon URL. The plugin generates a shareable link automatically; use the Code URL Override field if you want custom text at the end of the URL. In Redirect To URL, set where the customer lands after the coupon applies, and customize the success message if needed.

Send this URL by email, social media, or a site banner. Clicking it applies the coupon automatically.

How to Show the Discount Amount on Your Invoices

Once a coupon auto-applies, your order confirmation and invoice should reflect it. WooCommerce core doesn’t generate PDF invoices, so this requires a dedicated plugin such as Challan.

Challan generates a PDF invoice automatically when an order is placed and attaches it to the confirmation email. To show the discount amount on that invoice, go to Challan > Settings > Invoice, scroll to the Discount section, and enable Show Discounted Amount. Every invoice generated afterward reflects the applied coupon.
