have made effort @ read documentation?

• https://developer.intuit.com/docs/api/accounting/purchaseorder

please read documentation. documentation makes clear there 2 types of valid line.detailtype entries:

• item-based expense line
• account-based expense line

you using neither of those. fix code you're sending right data, , won't error.
