WooCommerce Integration

WooCommerce support requires RelayWP Pro.

What triggers a cache purge?

Event	Tags purged
Product stock change	`product:{id}`, `product_cat:{slug}` for all assigned categories
Product attribute update	`product:{id}`, all categories and tags
Product updated (any prop)	`product:{id}`, all categories and tags
Order status change	`wc:cart`, `wc:checkout`

Tag format for WooCommerce

RelayWP Pro uses these tag prefixes for WooCommerce content:

product:{id} — individual product
product_cat:{slug} — product category archive
product_tag:{slug} — product tag archive
wc:cart — cart page
wc:checkout — checkout page

Adding custom WooCommerce tags

add_filter( 'tagpurge_post_tags', function( array $tags, WP_Post $post ): array {
    if ( $post->post_type === 'product' ) {
        $tags[] = 'wc:shop'; // Always purge the Shop page too.
    }
    return $tags;
}, 10, 2 );
