Dropshipping with multiple fulfillment centers using shopify+shipstation

[Mikethecop]

Here is my situation:

I have a shopify site with a store.
I will have product line A fulfilled by a company that uses shipstation. I will also have product B that is fulfilled by a different company that also uses shipstation.

How can I ensure that when someone orders both A and B that the products are sent to the appropriate shipstations and then when they are respectively fulfilled by the different companies it talks aback to the order in shopify and marks it partially fulfilled and sends tracking, etc. 

In other words, I'm drop shipping with multiple companies that use shipstation and setting up the default third party fulfillment with an email isn't going to cut it.

Can I do this natively with shopify/shipstation or will it require a third party app? If an app, which one works best? Zapier or others? 

Thank you

If Shipstation is installed in your store, then you should be able to filter out which orders go to which warehouse, using Shipstation. If that's the case I would reach out to Shipstation for help setting that up.

If you don't have Shipstation in your store (like if your vendors are using it), you can send emails to the vendors using either an email filter (If using gmail you can create a filter to identify certain products by keyword, then forward that from your orders email to the vendor's email), or you can use an app like Order Automator that can identify products in orders and send the order information to a specific vendor based on the products in the order.
