How to create an invoice

[andrelfo2021]

Hello, I'm trying to integrate the creation of an invoice in Odoo from my net core 5 app. I managed to create the invoice and the lines , but the invoice does not appear in the list of invoices. Please does anyone have the solution or suggestions for this implementation?
Thanks in advance

I discovered that you need to do these things:

1. make sure the invoice model includes all of the required fields defined and create it first. (go through the model and look for required: true)

OdooInvoice = OdooDictionaryModel.Create(() => new AccountMoveOdooModel
{
PartnerId = ServiceContractProperty.OdooId,
Date = DateInvoiced,
InvoiceDate = DateInvoiced,
InvoiceDateDue = DateDue,
Ref = ServiceContractProperty.Property.Address,
State = StatusAccountMoveOdooEnum.Draft,
MoveType = TypeAccountMoveOdooEnum.CustomerInvoice,
IsStorno = false,
AutoPost = AutoPostAccountMoveOdooEnum.No,
CurrencyId = 1,
ExtractState = ExtractStateAccountMoveOdooEnum.WaitingValidation,

        });

2.) set the move_id in each lines model to the ID of the invoice you just created, then create all this lines.

I created the lines into a list of dictionaries: List<OdooDictionaryModel> lines
then for each line, set
line["move_id"] = moveId; //moveId is the Id of the invoice., just before you create it.

If you want a line not to be taxed, set the tax_ids to null. If you want them to be set to the default, leave the definition out. Otherwise set the tax_ids to the rates you want...
