Currently Amazon Seller-Fulfilled Prime Labels (Amazon Buy Shipping) are only supported when orders are received from the following sources:
-Amazon: Amazon Integration
-Linnworks: Linnworks Integration
-Channel Advisor: Channel Advisor - Integration
-Mintsoft API: API Help Page
Increasingly, clients are using Shopify as their central place for orders from multiple sources but we are unable to process Amazon Prime orders via Shopify as it's not supported on Mintsoft.
