通过一次通话获取Metafields产品的shopify

I have been trying to get metafields for over 100 products and that means I have to make separate 100 api calls for each product. If there is a way to grab all metafields for all products just in one xml file like the way variants are attached to products. So that with one api call, i grab all 100 products instead of making 100 separate api call for each product. Any help is appreciated.I have been trying to get metafields for over 1
