Choose which Shopify order number is sent to the other system.
Shopify has two versions of the order number:
order_number – the plain number, for example 1001.
name – the number including the prefix and suffix you have set in Shopify's general settings, for example #1001 or SE-1001.
No – send the plain order number.
Yes – send the order name, with prefix and suffix.
Turn this on if you want the order number in your accounting to look exactly like the one you and your customers see in Shopify.
