Save the e-invoice link

Saves an order's e-invoice data and link, and can also send the link to the marketplace.

POST https://out.stockmount.com/api/Integration/SetEinvoiceLink

Changes data

The order is found by store and marketplace order number (IntegrationOrderCode). With IntegrationOrderDetailIds only those marketplace line IDs are updated; otherwise all lines of the order. If the order number is not found in the store given by StoreId, you get Invalid order.; an order with the same number in another store is never updated.

Updated lines get the invoice number, invoice UUID, scenario, link and invoice date, and are marked as invoiced.

With SendEinvoiceToPlatform true the link is also sent to the marketplace. This is supported only for Trendyol, Hepsiburada, N11 and Pazarama stores. If sending fails the link is still saved, but Result is false and ErrorMessage is Invoice link saved successfully. Invoice link could not be sent: … (the rest is usually a Turkish marketplace/system message).

On success Message is Invoice link saved successfully. or Invoice link saved and sent successfully.; Response is empty.

Missing fields are reported together: 00003 with ErrorMessage like Missing: StoreId, InvoiceNumber, …. Send InvoiceTime in Turkey time without an offset.
