I am writing an app for my personal website to consume REST API and update Variant price and Inventory. I had a look in API docs but I could not find a REST call to update the variant by SKU. Is there anything I am missing or there is no API call to update the variant using SKU.
I am not looking for 3rd party paid app to achieve this. I know one solution would be to download all products and keep a local database of SKU and Shopify Variant ID. Then use Variant ID to update Price and inventory. But I was thinking there should be a way to use my SKU to update products.
