Hello team,
I have created a custom API for purchase invoices using AL Extension with OData. When I call this API via the GET method, it retrieves data successfully. However, when I call it via the POST method, the response indicates success, but it does not create the invoice in Business Central. Can you please suggest what the mistake in the AL extension code might be?
GET url: /ODataV4/Company({companyName})/CreatePurchaseInvoiceAPI
Post utl: /ODataV4/Company({companyName})/CreatePurchaseInvoiceAPI
Below, I have shared my code for creating purchase invoices.page 50073 /Custom Purchase Invoice API/
{
PageType = API;
Caption = 'Custom Purchase Invoice';
APIPublisher = 'MyPublisher';
APIGroup = 'businessCentral';
APIVersion = 'v1.0';
EntityName = 'customPurchaseInvoice';
EntitySetName = 'customPurchaseInvoice';
DelayedInsert = true;
SourceTable = /Purch. Inv. Header/;
SourceTableTemporary = true;
InsertAllowed = true;
