I am trying to print a custom packaging slip with a specific format and logo etc. The online template generator is not very helpful. I can generate a slip manually with HTML & PHP code and save it on my server. Is there a way to link that file as the custom slip for an order? Something like custom slip URL parameter in the create_order in the REST API?
Hello, I did the same for myself. ShipStation can not do this for you. Your web developer has to do this on your website back office. You can put your logo, address, thank you note. When you finish with all this, go to ShipStation connect your printer, and the size of the papers you are using.
