I am in the early planning stages of an integration project involving Dynamics SL, SalesForce and two in-house applications. There is data that needs to be synced between these systems and I need to be able to create AR invoices in Dynamics from sales information coming from an in-house system. It would appear that my only options for getting data into Dynamics are the Transaction Import and VBA or C# code written against the Solomon Object Model. I do not find either of these methods appealing as they both seem a bit cumbersome. Conversely, writing directly to the database seems a bit too risky.
Are these my only options?
