Shipping Rules Plugins

Updated 2 years ago

ShipBridge plugins can be used to apply shipping rules or customized invoices when shipping orders in ShipBridge. 

ShipBridge plugins are typically developed by SellerCloud and incur customization charges. Developers can use the instructions below to aid in development.

Add Plugins in ShipBridge

  1. Obtain your customized plugin from SellerCloud Support.
  2. Save it to the PC where ShipBridge is installed.
  3. In ShipBridge, open the menu and select Plugins.
  4. Click Install Plugin to open a File Explorer window to search for the plugin on your PC.
  5. Select the plugin and save.
  6. Check the box next to the plugin to enable it.

ShipBridge will call all enabled plugins to retrieve a shipping rule for each order. The plugins will be called whenever a new order is loaded to, or refreshed in the grid, or scanned in Scan & Ship.

Writing Plugins

The ShipBridge Extensibility Framework provides the IExtensibility interface–a proxy between plugins and ShipBridge.  IExtensibility allows quick access to such features as the “grids” and other shared instances.  Plugins are essentially .NET 2.0 assemblies. See attached sample VB.NET plugin below, ShipBridge.Plugin.Sample, which you can customize. 

The most important reference is ShipBridge.Extensibility, and the ShipBridge.Extensibility.dll is found in the ShipBridge application folder
  • It exposes the IPlugin interface which all plugins should implement
  • It provides access to ShipperHelper and PluginHelper which have easy-to-use properties and methods for checking orders 
IPlugin and SamplePlugin 

  • ID Each plugin should have a unique identifier (GUID). You can generate one from here 
  • DisplayName and Version keep the Plugins window updated with relevant information 
  • Handlers 
    • OnConnected is called every time ShipBridge initializes the plugin. You can call any initialization code here. 
    • OnOrderBeforeAddedToGrid is called immediately after a new order is received, but before any processing is made by ShipBridge itself. This is useful if a shipping method has to be selected before ShipBridge processes the order. 
    • OnOrderAfterAddedToGrid is the most frequently used handler. It’s called after ShipBridge has finished processing the order and allows plugins to select a proper shipping method. 
    • OnCellBeginEdit is called when the user starts making a change to a grid cell. This handler is rarely used. 
    • OnCellEndEdit is called after the user makes a change to a grid cell. This handler allows you to handle any address or weight changes so that the proper shipping method is selected.

PluginHelper provides quick access to frequently used order operations (getting or checking the state against another value, calculating its subtotal, weight, or checking if the order is “international,” to a military/US territory address and so on).

Instantiating a PluginHelper is done with a simple call by referencing the OrderData:

Dim helper As New PluginHelper(data)

The actual change of shipping service can be made by changing the helper.ShippingService to a ServiceInfo instance using ServiceInfo.GetByName. You can find a full ServiceInfo listing below. Of course, you can use any shipping rules based on destination, order subtotal, weight, etc. Example:

' si keeps the original shipping service, siNew will be the shipping

' rule-selected service. This is used to track shipping service changes.

Dim si As ServiceInfo = helper.ShippingService

Dim siNew As ServiceInfo = si



' If order address is POBox AND weight > 16 oz, use USPS Priority

  If helper.IsPOBox AndAlso helper.ShippingWeightInOz > 16 Then

RuleColor = GetColor(2)

siNew = ServiceInfo.GetByName("USPS Priority")

End If


' ... process any other shipping rules if necessary.


' Check if si is different than siNew, and if so, update helper.ShippingService

' and return TRUE, i.e. “service changed”

If si Is siNew Then

        ' Nothing has changed


            helper.ShippingService = siNew


Return True

      End If


It’s important to skip fully shipped or “ready for pickup” orders so that their shipping service is not altered. This can be done using the following code as used in the sample plugin:

' Skip FullyShipped and ReadyForPickup orders

If helper.ShippingStatus = OrderShippingStatus.FullyShipped OrElse elper.ShippingStatus = OrderShippingStatus.ReadyForPickup Then

Return False

End If

You can optionally skip rush or other orders by checking with the helper or another OrderData property.

' Leave this uncommented if rush orders should be skipped

If helper.RushOrder Then

Return False

End If
