szantogab / szamla-agent

Java client to communicate with szamlazz.hu API

Szamla-Agent

Java client implementation against the szamlazz.hu billing API.

Usage:

As a usual client you should instantiate hu.letscode.billing.service.factory.BillingServiceFactory and then create your own service with createSzamlaAgent method by passing two previously created objects:

BillingServiceFactory serviceFactory = new BillingServiceFactory();
SzamlaAgentBillingService billingService = serviceFactory.createSzamlaAgent();

The hu.letscode.billing.domain.Seller contains information about the selling entity.

Seller seller = new Seller();
seller.setAccountNumber("555555555-55555555-55555555");
seller.setBankName("whateverbank");
seller.setEmailContent("Pay your bill please");
seller.setEmailSubject("Invoice");
seller.setSellerSignatory("John Doe");

The hu.letscode.billing.domain.Settings contains information about the account you registered at szamlazz.hu and using szamlazz client with.

Settings settings = new Settings();
settings.setAnswerType(2);
settings.setDownloadBill(false);
settings.seteBill(false);
settings.setUser("letscodehu");
settings.setPassword("password");
settings.setKeyChainPassword("");

When you got the service up and running you could invoice bills with the createBill method. You only need to create BillingRequest's.

BillingRequest billingRequest = new BillingRequest();
billingRequest.setBuyer(createBuyer());
billingRequest.setSeller(createSeller());
billingRequest.setSettings(setSettings());
billingRequest.setHeader(createHeader());
billingRequest.setItems(createItemList());

billingService.createBill(billingRequest);

In order to create storno invoices you should use the revokeBill method. For that you need to construct BillRevokeRequests which is similar to the billingrequest and pass it over to the method:

BillRevokeRequest billingRequest = new BillRevokeRequest();
billingRequest.setBuyer(createBuyer());
billingRequest.setSeller(createSeller());
billingRequest.setHeader(createHeader());
billingRequest.setSettings(createSettings());

billingService.revokeBill(billingRequest);

Note that the revoke and create buyer/seller/header and settings objects are different.
