As you may know, we have a very popular international shipping app for Shopify. We also support the 3PL Central warehousing platform. We are constantly testing other platforms with Yakit and will publish blog articles on these. Stay tuned.
You can export orders from any platform in a csv or excel file and easily convert it into a Yakit Manifest. Our Support Yaks will be able to assist you in doing so. You can also push orders from your custom platforms via our easy REST API.
