You can use the bought together products also with a Shortcode. For example in a product page you can use the following shortcode. If not product id was defined our plugin tries to find the current global product, that was set:
[woocommerce_bought_together]
If you want to get specific bought together products for one product you can define a product ID in the shortcode as so:
[woocommerce_bought_together product_id="XX"]
