Changelog

We are happy to announce the beta release of our Go SDK. The SDK is maintained under sumup/sumup-go with its acompanying documentation at pkg.go.dev.

The Golang SDK provides easy access to SumUp APIs:

package main

import (
  "context"
  "log"
  "os"

  "github.com/sumup/sumup-go"
)

func main() {
  ctx := context.Background()
  client := sumup.NewClient().WithAuth(os.Getenv("SUMUP_KEY"))

  checkout, err := client.Checkouts.Create(ctx, sumup.CreateCheckoutBody{
    Amount:            123,
    CheckoutReference: "TX000001",
    Currency:          "EUR",
    MerchantCode:      "MK0001",
  })
  if err != nil {
    log.Printf("[ERROR] create checkout: %v", err)
    return
  }

  log.Printf("[INFO] checkout created: id=%q, amount=%v, currency=%q", *checkout.Id, *checkout.Amount, string(*checkout.Currency))

  checkoutSuccess, err := client.Checkouts.Process(ctx, *checkout.Id, sumup.ProcessCheckoutBody{
    Card: &sumup.Card{
      Cvv:         "123",
      ExpiryMonth: "12",
      ExpiryYear:  "2023",
      Name:        "Boaty McBoatface",
      Number:      "4200000000000042",
    },
    PaymentType: sumup.ProcessCheckoutBodyPaymentTypeCard,
  })
  if err != nil {
    log.Printf("[ERROR] process checkout: %v", err)
    return
  }

  log.Printf("[INFO] checkout processed: id=%q, transaction_id=%q", *checkoutSuccess.Id, string(*(*checkoutSuccess.Transactions)[0].Id))
}
