Every Business needs to ship. Xero is a good accounting software but it does not have shipping module. Infusionsoft is a good CRM but it does Not ave a shipping Module for the shopping cart.
http://Shipstation.com is very popular with many of the shopping cart software. It would be great to get the integration with it and it will act as a conduit to all of the other shopping carts.
Regarding Shipstation, while we do not have it in the roadmap yet, its API seems to be compatible with our HTTP or SDK connector. You can see more information in our documentation: http://docs.workato.com/developing-connectors/http-vs-sdk.html
We will update you again if this application is added to the roadmap.
