How to Import Shopify Mass Orders into NetSuite

Issue:

We want to load test Shopify Orders pushing into NetSuite. We have a production site full of orders. We would like to pass those orders or somehow mass creates orders in Shopify that would trigger our flow.

Currently, we tried an order load tool but it didn't trigger our flow.

Resolution:

What value is set on the Integration App setting for "Add web orders into NetSuite"?  If the value is set to "When they are Captured in Shopify" and the tool uses Order resource API to upload orders in "paid" financial status, then due to this Shopify issue, the order import flow won't be triggered for those orders.

How to import those mass orders into NetSuite?
If your intention is to just import those orders into NetSuite regardless of the financial status, authorized/paid, then switch the advanced setting for "Add web orders into NetSuite" to "When they are Authorized in Shopify".  This will ensure the order import flow is triggered for all those orders (Note: if an order is placed in an authorized status during this time period, the flow will be triggered for those orders as well). 
And once the process is complete, switch the settings as per your requirements.
