I am able to POST and invoice EntityType to the Web API.
After creating the invoice I get the guid and I want to create invoice line items, which I believe are of invoicedetail EntityType.
I cannot POST a new invoicedetail. Every attempt I make with a range of different properties I receive either an Error 500 - An unexpected error occurred. or Error 500 - The parent id is missing.
An example of a JSON string I'm trying to POST. (invoicedetailid is the GUID of the previous invoice I create)
{
"productdescription": "Test Line Item",
"invoicedetailid": "00000000-0000-0000-0000-0000000000000",
"priceperunit": 10,
"tax": 0,
"quantity": 1,
"baseamount": 10
}
The documentation is vague and I'm wanting to know, what are the minimum required fields for invoicedetail and how can I POST a new invoice EntityType?
The field storing to lookup from invoicedetail to invoice is called invoiceid (not invoicedetailid, which is the id of the invoicedetail itself). Additionally, you need to use the @odata.bind-annotation:
To associate new entities to existing entities when they are created you must set the value of single-valued navigation properties using the @odata.bind annotation.
The body of your POST request would thus look as follows:
{
"productdescription": "Test Line Item",
"invoiceid@odata.bind": "/invoices(guid-of-invoice-here)",
"priceperunit": 10,
"tax": 0,
"quantity": 1,
"baseamount": 10
}
