Checkout.com API client

This repo contains Checkout.com API client written in Go.

Checkout.com API documentation: https://docs.checkout.com/v2.0/docs/integration-options

Before using this client you need to register an account.

How to install

Download package:

go get github.com/gojuno/go-checkout

Client uses github.com/pkg/errors, so you may need to download this package as well:

go get github.com/pkg/errors

Go modules are supported as well.

How to use

To init client you will need secret_key which you can get from your Checkout.com account profile.

import "github.com/gojuno/go-checkout"
...
// Init client
client := checkout.New(
	checkout.OptSecretKey("your_secret_key"),
)

// Create new payment
payment, err := client.Payment().Create(
	context.Background(),
	"payment_idempotency_key",
	&checkout.CreateParams{
        Source:   checkout.Source{
            Type: checkout.SourceTypeID,
            ID:   "src_vjkl7cyod4zejpkk5dwpvla7ca",
        },
        Amount:   2000,
        Currency: "USD",
	},
)

Custom HTTP client

By default client uses http.DefaultClient. You can set custom HTTP client using checkout.OptHTTPClient option:

httpClient := &http.Client{
	Timeout: time.Minute,
}

client := checkout.New(
	checkout.OptSecretKey("your_secret_key"),
	checkout.OptHTTPClient(httpClient),
)

You can use any HTTP client, implementing checkout.HTTPClient interface with method Do(r *http.Request) (*http.Response, error). Built-in net/http client implements it, of course.

Sandbox

Checkout.com supports sandbox and live environment. By default, client will use live endpoint. To use sandbox define sandbox endpoint when client is created.

client := checkout.New(
	checkout.OptSecretKey("your_secret_key"),
	checkout.OptEndpoint(checkout.EndpointSandbox),
)
