This support article discusses how to get your ShipStation account to communicate with your Lead Commerce deployment.
In order for Lead Commerce to successfully load your ShipStation orders into the back office, you need to create a custom Attribute field called "ShipStation SKUs". The SKU is a unique identifier for your stock keeping unit on sales channel and it is what ShipStation provides via their API in order to identify what has been ordered by your customers.
To successfully import an order, Lead Commerce must be able to correlate what Lead Commerce SKU equals the SKU value being provided from ShipStation.
If you have access to Attributes and understand how to create them, then you may create the Attribute "ShipStation SKUs" (as "Large Text Area" type) on your own and apply that Attribute to SKUs in your back office. For more information on creating custom Attributes, please see this support article.
Alternatively, if you are not sure how to perform this task, you can always open a support ticket and request assistance.
Now that you have your attribute created, you will need to associate your Lead Commerce SKUs with your ShipStation items by filling out this attribute for each SKU. For example, on Lead Commerce SKU #3 you would fill the ShipStation SKUs field with "mySKU01". Do this for each item that you sell on this ShipStation channel.
Note: if you have a different SKU for different sales channels that come through ShipStation, you can comma separate your SKU names in this attribute field (ie "mySKU01,alternateSKU01").
you have your ShipStationSKUs loaded into Lead Commerce for each SKU,
contact support and supply your ShipStation credentials so that the App
Connector can be installed for your account.
