So a "known" issue that has no time frame for solution is draft orders greater than 100 lines can not get a discount - it errors our.
Supports solution is to do multiple invoices, but in our case that would mean 4 invoices.
Our customer requires one as it is part of a purchase order request that needs one invoice.
Can someone provide some guidance on using API Post to upload a draft invoice with discounts (flat 5%)
I have an export of the saved draft order (without the required discount) and google sheets with API connector
Support could not even confirm if this would work if attempted!
