Usage examples

Using APIs with APIKey

import (
	"github.com/adyen/adyen-go-api-library/src/checkout"
	"github.com/adyen/adyen-go-api-library/src/common"
	"github.com/adyen/adyen-go-api-library/src/adyen"
)

client := adyen.NewClient(&common.Config{
    ApiKey:      "your api key",
    Environment: common.TestEnv,
})

res, httpRes, err := client.Checkout.PaymentMethods(&checkout.PaymentMethodsRequest{
    MerchantAccount: "your merchant account",
})

Using APIs with APIKey for Live env

import (
    "github.com/adyen/adyen-go-api-library/src/checkout"
    "github.com/adyen/adyen-go-api-library/src/common"
	"github.com/adyen/adyen-go-api-library/src/adyen"
)

client := adyen.NewClient(&common.Config{
    ApiKey:      "your api key",
    Environment: common.LiveEnv,
    LiveEndpointURLPrefix: "1797a841fbb37ca7-AdyenDemo", // Refer to https://docs.adyen.com/development-resources/live-endpoints#live-url-prefix
})

res, httpRes, err := client.Checkout.PaymentMethods(&checkout.PaymentMethodsRequest{
    MerchantAccount: "your merchant account",
})

Using API with Basic Auth

import (
    "github.com/adyen/adyen-go-api-library/src/recurring"
    "github.com/adyen/adyen-go-api-library/src/common"
	"github.com/adyen/adyen-go-api-library/src/adyen"
)

client := adyen.NewClient(&common.Config{
    Username:        USER,
    Password:        PASS,
    Environment:     common.TestEnv,
    ApplicationName: "adyen-api-go-library",
})

res, httpRes, err := client.Recurring.ListRecurringDetails(&recurring.RecurringDetailsRequest{
    MerchantAccount: MerchantAccount,
    Recurring: &recurring.RecurringType{
        Contract: "RECURRING",
    },
    ShopperReference: "ref",
})

Using Notifications parser

import (
    "github.com/adyen/adyen-go-api-library/src/adyen"
    "github.com/adyen/adyen-go-api-library/src/common"
)

client := adyen.NewClient(&common.Config{
    ApiKey:      "your api key",
    Environment: common.TestEnv,
})

notification, err := client.Notification.HandleNotificationRequest(jsonRequestString)

Getting error details

import (
	"github.com/adyen/adyen-go-api-library/src/common"
	"github.com/adyen/adyen-go-api-library/src/checkout"
	"github.com/adyen/adyen-go-api-library/src/adyen"
)

client := adyen.NewClient(&common.Config{
    ApiKey:      "your api key",
    Environment: common.TestEnv,
})

res, httpRes, err := client.Checkout.Payments(&checkout.PaymentRequest{
    Reference: "123456781235",
    Amount: checkout.Amount{
        Value:    1250,
        Currency: "EUR",
    },
    CountryCode:     "NL",
    MerchantAccount: MerchantAccount,
    Channel:         "Web",
    ReturnUrl:       "http://localhost:3000/redirect",
    PaymentMethod: map[string]interface{}{
        "type":   "ideal",
        "issuer": "1121",
    },
})

errorText := err.Error()
errorMessage := err.(common.APIError).Message
errorCode := err.(common.APIError).Code
errorType := err.(common.APIError).Type

httpStatusCode := httpRes.StatusCode
httpStatus := httpRes.Status

Custom HTTP Client Configuration

By default, Go http.DefaultClient will be used to submit requests to the API. But you can change that by injecting your own HttpClient on your client instance.

client := adyen.NewClient(&common.Config{
    HTTPClient:  &http.Client{
        CheckRedirect: redirectPolicyFunc,
        Timeout: 10 * time.MilliSeconds,
    },
    Environment: common.TestEnv,
    ApiKey:      "your api key",
})

Proxy configuration

You can configure a proxy connection by injecting your own http.Client with a custom Transport on your client instance.

Example:

//creating the proxyURL
proxyURL, _ := url.Parse("http://myproxy:7000")
transport := &http.Transport{
    Proxy: http.ProxyURL(proxyURL),
}
client = adyen.NewClient(&common.Config{
    HTTPClient:  &http.Client{
        Transport: transport,
    },
    Environment: common.TestEnv,
    ApiKey:      "your api key",
})
