Is there a test mode for the Facebook & Instagram channel?

My company has developed an integration between Shopify and our own system (SalesPad) which imports orders from Shopify into our system. One of our customers uses the Facebook & Instagram channel to take orders in Facebook and import them into Shopify. When our integration tries to import those Facebook-originating Shopify orders into our system, our integration misbehaves in strange ways.

In order to diagnose and fix these issues, we would like to use the Facebook & Instagram channel using test transactions instead of having to formally setup a Facebook store with real company information and operate with real money. Is there any way this can be done?
