This SDK is no longer maintained and should not be used for new projects. There may be a newer version with support for our API v2 in the future.

The merchant credentials, which are necessary to handle payments with Barzahlen, can be received at https://partner.barzahlen.de. After a successful registration a shop ID is assigned to you as well as a payment and a notification key. Furthermore you can set you callback URL, which is used to send updates on payment and refund transactions.
Requests errors are able to throw exceptions, so it's recommended to enclose them in a try/catch block, so the errors can be managed properly.
You can find examples how to use the sdk under src/main/java/test/de/barzahlen/api/online/integration
If you want to use another HttpClient than HttpsURLConnection, you can create your own and implement the interface HttpClient.
There is a logger that puts all messages to the console. If you want to use your own, you can implement the interface Logger.
Logger logger = LoggerFactory.getLogger(LoggerFactory.LoggerType.CONSOLE); // Get the console LoggerIf you want to use another HttpClient than HttpsURLConnection, you can create your own and implement the interface HttpClient.
For logging all HttpRequests you can use the LoggingClient. It has two parameters: the httpClient and the logger
HttpClientFactory.getHttpClient(HttpClientFactory.HttpClientType.HttpsURLConnection); // Get the HttpClient
HttpClient loggingClient = new LoggingClient(httpClient, logger); // Create LoggingClientYou can send requests by create an instance of a Request class and pass it to the handle method of the BarzahlenApi Class.
HttpClient httpClient = HttpClientFactory.getHttpClient(HttpClientFactory.HttpClientType.HttpsURLConnection);
Configuration configuration = new Configuration(SANDBOX_MODE, SHOP_ID, PAYMENT_KEY, NOTIFICATION_KEY);
BarzahlenApi barzahlenApi = new BarzahlenApi(httpClient, configuration);
TransactionCreateRequest createRequest = new TransactionCreateRequest();
createRequest.setTransactionCreateResultHandler(new TransactionCreateResultHandler() {
@Override
protected void onSuccess(final String transactionId, final String paymentSlipLink, final String expirationNotice, final String infotext1, final String infotext2) {
}
@Override
protected void onError(final String result, final String errorMessage, final int httpResponseCode) {
}
})
createRequest.initialize(transaction);
barzahlenApi.handle(createRequest);For using notifications, you must implement HttpRequest and HttpResponse and pass it to BarzahlenNotificationHandler.handleRequest. Here is an example for servlets:
public class ServletRequest implements HttpRequest {
private HttpServletRequest httpServletRequest;
@Override
public String getPath() {
return httpServletRequest.getPathInfo();
}
@Override
public Map<String, String> getParameters() {
return httpServletRequest.getParameterMap();
}
}public class ServletResponse implements HttpResponse {
private HttpServletResponse httpServletResponse;
@Override
public OutputStream getOutputStream() {
return httpServletResponse.getOutputStream();
}
@Override
public void setHeader(final String name, final String value) {
return httpServletResponse.setHeader(name, value);
}
