Querying custom taxonomy terms is the same as querying categories, and as you can see from the docs you can change the number returned using the per_page argument: http://…../wp-json/wp/v2/product_categories?per_page=100

Both parent and child_of need an integer as value, which would in both cases be … Read more
WordPress tracks which object types taxonomy applies to. This can be established on taxonomy registration or at some point after, so you shouldn’t be trying to do this too early.
