WooCommerce REST API GET multiple products by ID
you could use parameter 'include' to achieve that like below :
site.com/wp-json/wc/v2/products/?include=5,6,7,8,9This will limit results to specific Id's.
On version 3 of Woocommerce it should be
https://test.com/wp-json/wc/v3/products?consumer_key=ck_&consumer_secret=cs_&include=1,2,3
