I’m trying to delete all WooCommerce webhooks, but after doing so they still appear as “Disabled” in the advanced settings -> webhooks interface.

I’ve been trying to do this:

$webhook_ids = $wpdb->get_col("SELECT webhook_id FROM {$wpdb->prefix}wc_webhooks");
foreach( $webhook_ids as $webhook_id )
{
    // Get the webhook
    $webhook = new WC_Webhook( $webhook_id );

    // Delete the webhook
    $webhook->delete( TRUE ); // true to force delete
}

I’ve even tried doing this:

$wpdb->query("DELETE FROM wp_wc_webhooks");

And I’ve also tried doing this:

$webhook_ids = $wpdb->get_col("SELECT webhook_id FROM {$wpdb->prefix}wc_webhooks");
foreach( $webhook_ids as $webhook_id )
{
    // Get the webhook
    $webhook = new WC_Webhook( $webhook_id );

    // Delete the webhook
    $webhook->delete( TRUE ); // true to force delete

    $WC_Webhook_Data_Store = new WC_Webhook_Data_Store();
    $WC_Webhook_Data_Store->delete( $webhook );
}

No matter what I do, the result is the same. A list of “Disabled” webhooks in the admin area. What’s interesting is that the wp_wc_webhooks table is empty. I know there is a cache, but I was under the impression that using the delete method of the WC_Webhook_Data_Store should clear it.

What can I do to get rid of these pesky “Disabled” webhooks?
