Create Coupons Programmatically

The inspiration for this tutorial was another tutorial I found where it was recommended to create WooCommerce coupons using wp_insert_post() function and update_post_meta(). When working with WooCommerce data since 3.0 version it is always recommended to use CRUD objects. And coupons are not an exception.

In order to create a coupon programmatically in code we have to use WC_Coupon object. Once the object is created we are able to use its methods for coupon configuration.

Let’s do it and begin with something simple.

$coupon = new WC_Coupon();

$coupon->set_code( 'blackfrd' ); // Coupon code
$coupon->set_amount( 200 ); // Discount amount

$coupon->save();

As you could’ve guessed, two methods set_code() and set_amount() are more than enough to create a coupon.

As simple as that. The only thing you have to double check before using this code is that WooCommerce is actually loaded, otherwise you will get Fatal error: Uncaught Error: Class ‘WC_Coupon’ not found in blah blah. Just consider using plugins_loaded action hook if you’re going to create a coupon in your custom plugin.

With that – done! What about some coupon configuration now?

Let’s create another coupon right now and configure everything like on the screenshot.

$coupon = new WC_Coupon();

$coupon->set_code( 'ny_eve_2022' );

$coupon->set_description( 'Some coupon description.' );

// General tab

// discount type can be 'fixed_cart', 'percent' or 'fixed_product', defaults to 'fixed_cart'
$coupon->set_discount_type( 'percent' );

// discount amount
$coupon->set_amount( 20 );

// allow free shipping
$coupon->set_free_shipping( true );

// coupon expiry date
$coupon->set_date_expires( '31-12-2022' );


// Usage Restriction

// minimum spend
$coupon->set_minimum_amount( 1000 );

// maximum spend
$coupon->set_maximum_amount( 50000 );

// individual use only
$coupon->set_individual_use( true );

// exclude sale items
$coupon->set_exclude_sale_items( true );

// products
$coupon->set_product_ids( array( 132 ) );

// exclude products
$coupon->set_excluded_product_ids( array( 15, 16 ) );

// categories
$coupon->set_product_categories( array( 17 ) );

// exclude categories
$coupon->set_excluded_product_categories( array( 19, 20 ) );

// allowed emails
$coupon->set_email_restrictions( 
	array( 
		'no-reply@rudrastyh.com', 
		'kate@rudrastyh.com',
	)
);


// Usage limit tab

// usage limit per coupon
$coupon->set_usage_limit( 100 );

// limit usage to X items
$coupon->set_limit_usage_to_x_items( 10 );
	
// usage limit per user
$coupon->set_usage_limit_per_user( 2 );

$coupon->save();

The only thing I would like to highlight here is that you can also pass variation IDs in set_product_ids() and set_excluded_product_ids() methods.
