WooCommerce - Create a coupon via PHP

gistfile1.txt

$coupon_code = 'UNIQUECODE'; // Code
$amount = '10'; // Amount
$discount_type = 'fixed_cart'; // Type: fixed_cart, percent, fixed_product, percent_product
					
$coupon = array(
	'post_title' => $coupon_code,
	'post_content' => '',
	'post_status' => 'publish',
	'post_author' => 1,
	'post_type'		=> 'shop_coupon'
);
					
$new_coupon_id = wp_insert_post( $coupon );
					
// Add meta
update_post_meta( $new_coupon_id, 'discount_type', $discount_type );
update_post_meta( $new_coupon_id, 'coupon_amount', $amount );
update_post_meta( $new_coupon_id, 'individual_use', 'no' );
update_post_meta( $new_coupon_id, 'product_ids', '' );
update_post_meta( $new_coupon_id, 'exclude_product_ids', '' );
update_post_meta( $new_coupon_id, 'usage_limit', '' );
update_post_meta( $new_coupon_id, 'expiry_date', '' );
update_post_meta( $new_coupon_id, 'apply_before_tax', 'yes' );
update_post_meta( $new_coupon_id, 'free_shipping', 'no' );

@dcx15 yikes it's 8 years old but it should work. However, I'd suggest looking into using the WC_Coupon class instead. https://docs.woocommerce.com/wc-apidocs/class-WC_Coupon.html

Thanks for confirming Mike!

For anyone else that stumbled on this gist via Google, I found this answer on SO useful https://stackoverflow.com/a/61874195. All of the other blog posts and SO answers seem to be very outdated in Google results.

How can we add something like add X quantity of any product and get Y % off?

Better using the wc_coupon instance with its save method now.

@mikejolley Does this work in 2023? I'm just starting a new store with my own designs and I can't really afford to pay for those 50$ a month plugins (not before I will actually start making some money on this :D)
Thank you for all the effort you put in this so far!
