Ship&co has integrated with API of Seino transportation since early this year (2021), starting from the App service, allowing Seino users to easily print Seino shipping labels. This month, Ship&co now updates parameters for Seino service, enabling API users to print Seino labels inside their system.

*Please be noted that Seino is NOT available with the test flag so you will need to print Seino shipping label in the production.

Check out this API document to update Seino parameter to your system!
