Hungarian Invoicing is a Scala library to interface with NAV Online Invoicing API 3.0.
Add Enliven Systems repository:
resolvers ++= Seq("Enliven Systems Central" at "https://central.enliven.systems/artifactory/sbt-release/")
Add as a dependency:
"systems.enliven.invoicing.hungarian" %% "core" % "1.0.X"
(For current and released version see version.sbt. version.sbt contains the next patch release.
For example, if you see version 1.0.54 there, the current release is 1.0.53.)
Please note that currently we only provide Scala 2.13 builds. Drop us a message in case you need a build for Scala 2.11 or Scala 2.12. Java port is possible. See more info below.
You may have to add NAV servers to your Java trust store manually, otherwise you'll get errors
like: General SSLEngine problem.
For this we include a script in /development/import-certificates.sh. Please fine-tune the
script to your needs, especially by setting your JAVA_HOME correctly.
See section about the configuration. You will have to provide test API credentials for tests to work: some of them directly connect to NAV servers.
sbt test
Each build is released with 52+ tests succeeds on our CI. Running tests with a proper configuration you should see:
[info] Tests: succeeded 61, failed 0, canceled 0, ignored 0, pending 0
Create a configuration.
import systems.enliven.invoicing.hungarian.core.Configuration
implicit val configuration = new Configuration()
Add your own invoice-hungarian.conf to the classpath to override any value.
Defaults are the following (invoice-hungarian.defaults.conf bundled with the package):
invoicing-hungarian {
connection {
# The number of Connection actors in the ConnectionPool.
pool = 6
# The maximum number of consequent retries to refresh the exchange token if network error occurs
# API error will not be retried.
maxRetry = 10
}
}
Add invoice-hungarian.conf with the following content. Please note that these are exemplary
values, do not use them directly!
invoicing-hungarian {
authentication {
signing-key = "ds-fj92-89r32hADSAKLFH4738FJSAAA"
exchange-key = "92NASJKASNJK1289"
login = "932j29h329fhdss"
password = "g9h8g893fh9dhf29"
}
entity {
tax-number = "25962295"
}
request {
base = "https://api-test.onlineszamla.nav.gov.hu/invoiceService/v3/"
}
software {
identifier = "ENLIVEN25962295207"
name = "Enliven Systems Invoicing Hungarian"
version = "1.0.0"
developer = {
name = "Enliven Systems Kft."
contact = "[email protected]"
country-code = "HU"
tax-number = "25962295-2-07"
}
}
}
Instantiate the API.
import systems.enliven.invoicing.hungarian._
import systems.enliven.invoicing.hungarian.api.Api.Protocol.Request.Invoices
import javax.xml.bind.DatatypeConverter
import scala.concurrent.duration._
val invoicing = new Invoicing()
invoicing.awaitInit()
or initialize the API asynchronously
invoicing.init()
Create a few invoices.
val invoice: Invoices.Invoice =
Invoices.Raw(Invoices.Operation.storno, DatatypeConverter.parseBase64Binary("something"))
val validInvoices = (1 to 100).map(_ => invoice)
Alternatively you can use other type of invoices, for example directly provide the protocol object
as in Invoices.Protocol or use a limited, but self-validating class Invoices.Smart. See tests
and code for examples.
Use the synchronous API,
invoicing.invoices(Invoices(validInvoices))(10.seconds)
or the asynchronous API backed by AKKA.
invoicing.invoices(Invoices(validInvoices), 10.seconds)(10.seconds)
Please note that you don't have to request exchange tokens. The API will do it for you.
The API uses a connection pool that you may fine tune to get the maximum throughput for your application.
Provide your own actor.conf to fine-tune the underlying AKKA actor system, for example:
akka {
actor {
priority-dispatcher {
type = "Dispatcher"
mailbox-type = "systems.enliven.invoicing.hungarian.behaviour.PriorityMailbox"
}
blocking-dispatcher {
type = "Dispatcher"
executor = "thread-pool-executor"
thread-pool-executor {
fixed-pool-size = 6
}
throughput = 1
}
}
http.host-connection-pool.max-open-requests = 128
}
Provide your own logging by adding a log4j2.properties to your classpath, for example:
status = error
appenders = console
appender.console.type = Console
appender.console.name = STDOUT
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = %d{${LOG_DATEFORMAT_PATTERN:-MM-dd HH:mm:ss.SSS}} %highlight{${LOG_LEVEL_PATTERN:-%5p}}{FATAL=red blink, ERROR=red, WARN=yellow bold, INFO=green, DEBUG=green bold, TRACE=blue} %style{%12.12t}{magenta} %style{%20.20replace{%c{1.}:%L}{}{}}{cyan} %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%rEx}
appender.console.layout.disableAnsi = false
loggers = hungarian
logger.hungarian.name = systems.enliven.invoicing.hungarian
logger.hungarian.level = trace
rootLogger.level = error
rootLogger.appenderRefs = stdout
rootLogger.appenderRef.stdout.ref = STDOUT
