SalesInvoiceLines not being created when using the API

Hello,

I have been using the Business Central API now for 2.5 years. I built an application to sync our on-premise inventory system with Business Central. These POST API calls work fine and they have not changed since I implemented the application: customers, item categories, and items.

When I built the application, I used the SalesOrders endpoint and was able to submit the following JSON and it would create the Sales Order with the Sales Order Lines.

{    /customerId/: /{{customerId}}/,    /externalDocumentNumber/: /{{orderId}}/,    /salesperson/: /{{SalesPerson}}/,    /shippingPostalAddress/: {        /street/: /{{address1}}/,        /city/: /{{city}}/,        /state/: /{{state}}/,        /countryLetterCode/: /{{country}}/,        /postalCode/: /{{postcode}}/    },    /salesOrderLines/: [        {            /sequence/: 10000,            /itemId/: /{{line1_itemId}}/,            /quantity/: {{line1_qty}},            /shipmentDate/: /{{shipDate}}/        },        {            /sequence/: 20000,            /itemId/: /{{line2_itemId}}/,            /quantity/: {{line2_qty}},            /shipmentDate/: /{{shipDate}}/        }    ]}

About 6 months ago, the API started erroring and I found that the SalesOrders endpoint no longer accepted the salesOrderLines property/array. I needed to switch the application and make multiple posts requests to the /salesInvoices({{invoice_id}})/salesInvoiceLines endpoint to get the line items to show up.

Sales Invoice

{    /customerId/: /{{customerId}}/,    /externalDocumentNumber/: /{{orderId}}/,    /salesperson/: /{{SalesPerson}}/,    /shippingPostalAddress/: {        /street/: /{{address1}}/,        /city/: /{{city}}/,        /state/: /{{state}}/,        /countryLetterCode/: /{{country}}/,        /postalCode/: /{{postcode}}/    }}

Sales Invoice Line 1

        {            /sequence/: 10000,            /itemId/: /{{line1_itemId}}/,            /quantity/: {{line1_qty}},            /shipmentDate/: /{{shipDate}}/        }

Sales Invoice Line 2

        {            /sequence/: 20000,            /itemId/: /{{line2_itemId}}/,            /quantity/: {{line2_qty}},            /shipmentDate/: /{{shipDate}}/        }

Now the sync application is intermittently failing to create the Sales Invoice Lines for a given invoice. I looked through all of the Microsoft Business Central documentation for the Sales Invoice APIs and found that it is the same request that I am sending. But I am getting a 400 Bad Request error.

I have tried both of the URLs found here: https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/api-reference/v2.0/api/dynamics_salesinvoiceline_create and neither work. Both return the 400 Bad Request error.

I cannot seem to find an updated schema maps or change history notes for why the endpoints would just stop working for the Sales Invoice Lines. I am not submitting anything fancy, just the itemId, quantity, and unitPrice.

This is causing a lot of delay in the accounting department. Any help would be appreciated.

Thanks,

Travis
