go-finance's Introduction

go-finance

This is a Golang library which contains finance related functions.

Exchange Rates

The following example explains how to use this package to retrieve the exchange rates from ECB:

package main

import (
	"fmt"
	"os"

	"github.com/pieterclaerhout/go-finance"
)

func main() {

	rates, err := finance.ExchangeRates()
	if err != nil {
		fmt.Println("ERROR:", err.Error())
		os.Exit(1)
	}

	for currency, rate := range rates {
		fmt.Println(currency, "-> €1 =", rate)
	}

}

Checking VAT Numbers

You can also VAT numbers via the VIES service. The following sample code shows how to do this:

package main

import (
	"fmt"
	"os"

	"github.com/pieterclaerhout/go-finance"
)

func main() {

	info, err := finance.CheckVAT("BE0836157420")
	if err != nil {
		fmt.Println("ERROR:", err.Error())
		os.Exit(1)
	}

	fmt.Println(info)

}

IBAN & BIC

There is also a function which converts a regular Belgian Bank Account Number to it's IBAN / BIC equivalent:

package main

import (
	"fmt"
	"os"

	"github.com/pieterclaerhout/go-finance"
)

func main() {

	info, err := finance.CheckIBAN("738120256174")
	if err != nil {
		fmt.Println("ERROR:", err.Error())
		os.Exit(1)
	}

	fmt.Println(info)

}

Add support for IBAN / BIC

Sample code

// Create the soap client
$client = new SoapClient(
    "http://www.ibanbic.be/IBANBIC.asmx?WSDL"
);

// Create the function arguments
$args = array('Value' => $this->number);

// Call the function
$result = array();
$result['bank'] = (array) $client->BBANtoBANKNAME($args);
$result['iban'] = (array) $client->BBANtoIBAN($args);
$result['bic']  = (array) $client->BBANtoBIC($args);

// Clean up the result
$result['bank'] = $result['bank']['BBANtoBANKNAMEResult'];
$result['iban'] = $result['iban']['BBANtoIBANResult'];
$result['bic']  = $result['bic']['BBANtoBICResult'];
