Create an order from an external data source

[ronniestamps]

What would be the best way to create an order from an external data source? The external data source is a CRM on a different domain. Is this available in the api? Should I use

Code Select Expand

_createOrder($_cart, $_usr, $_prices) contained in administrator/components/com_virtuemart/models/orders.php?


VM 2.0.20b
Joomla 2.5.9

Any advice is much appreciated.
Thank you in advance,

Ronnie

I think I may have answered my own question or at least closer to the answer...

Could I create a $cart object on the CRM on domain X and pass it to

Code Select Expand

createOrderFromCart($cart) on domain Y using JSON?
