About

This library is an implementation for Klarna payment API in go

How to use

Configuration

Config struct encapsulate the client needs of information

type Config struct {
	BaseURL     *url.URL
	APIUsername string
	APIPassword string
	Timeout     time.Duration
}

Client

Is the abstraction of HTTP client, required by each service in order to operate.

import (
        klarna "github.com/Flaconi/go-klarna"
        "net/url"
        "time"
)

func main() {
        uri, _ := url.Parse(klarna.EuroAPI)
        conf := klarna.Config{
                BaseURL:uri,
                Timeout: time.Second * 10,
        }
        client := klarna.NewClient(conf)
}

Now since we have an instance of the client, we can instantiate any service instance with this client ...

Service

Now, since we have a client, let's instantiate a service

import (
        // ...
)

func main() {
        // previous section ...
        client := klarna.NewClient(conf)

        // payment service
        paymentSrv := klarna.NewPaymentSrv(client)
        err := paymentSrv.CancelExistingAuthorization("string-token")
        if nil != err {
                // do something with the error
        }
}
