Import Shopify Products to Amazon for Amazon MCF

Hi guys, I’m looking to import our Shopify products to Amazon Seller Central because we’re looking to use Amazon MCF. We’re not going to sell on Amazon, we just want to integrate Shopify to Amazon fulfillment. What would be the best way? We have 100 original products and it seems like we need to apply for Catalog Authorization for all our products. Is that correct?

​

I feel like it would be too exhausting and would take so much time, is there any other way we could do this? Would using an app/plugin can automatically do all the work?

​

Any help would be much appreciated!
