Unifaun Online Integration

Shopify Unifaun Integration sync shipping details from Shopify store to your Unifaun Online konto. You can let the sync happen automatically and instantly when an order is received in Shopify store, or you can choose to control everything manually. The integration support all major transportation companies and all carrier services that are available in Unifaun Online. Supports multiple delivery agents simultanously, so each shipping option in the store can be mapped to different transport services. Enjoy!

How does the app work?

When a new order is placed in your Shopify store, Shopify will immidiately notify Uniwin App about this event which in turn will trigger sync of the order details from the store to your Unifaun Online account. If you have automatic sync enabled (default), all this will happen instantly and you will be able to find a shipping label inside you Unifaun Online account few seconds after the order is placed in Shopify. For printing the label you must login to Unifaun Online and use the printing feature from the dashboard. The sync is done with XML posting into your Unifaun  Online account.

Each Shipping Zone or Shipping Option in your store can be connected to different carrier services or Printing Favorites in Unifaun Online. When you connect a Shipping Option to a carrier service it is called a Simple Mapping. And if you connect a Shipping Option to a Printing Favorite in Unifaun Online the it is an Advanced Mapping, because more advanced features are possible with this option.

The Simple Mapping is easy to do. On the drop down menu on the “Mapping” page you simply select your shipping option, and then the carrier name you want to connect it to and click on save button. This will create a shipping label for you when you receive new orders in your store.
For Advanced Mapping you need to first understand the Printing Favorite feature in Unifaun Online. Then you can create a valid Printing Favorite and connect it to your Shopify Shipping Option through our Uniwin App.
We recommend you to always start using the simple mapping and the change to Advanced Mapping if you need more features.

In orders preview page, there is an option for Print label(See Screenshot).

Advanced Mapping is when you associate a Shopify Shipping Option with a Printing Favorite in Pacsoft Online. Simple Mapping is when associate a Shopify Shipping Option with a carriers service using the drop down selection menu. A valid shipping label that is ready to print contains all necessary variables. When you use the Simple Mapping some of those necessary variables are not filled in, so the label will have status INVALID. You have to then open the shipping label by clicking the small arrow sign near the label and fill in the missing values for finalizing the shipping label. Then you can print it.

The usage of tracking in our app is causing this. When tracking is enabled, Uniwin app sets the status to open. To avoid this fulfillment status, you have to disable the tracking method by setting it to None.

We provided the option to create both CN23 documents and commercial invoices through our app by enable the “Commercial/Proforma Invoices” checkbox.

You can change the customs currency in the unifuan 1 app’s customs information tab, as shown in the image.

When you are mapping a Shopify shipping option (for instance Standard Shipping) to a carrier service (for instance DHL Express) then there are several values necessary to make the label VALID, and those values are obviously not set. So map your Shopify shipping option to a Unifaun Printing Favorite to get a VALID label. You find video guide and written PDF instruction on our website.
