Golang SDK

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))
}

Android SDK 4.3.0

Android SDK 4.3.0 has been released.

Solo USB (Beta)

The Solo card reader now supports connecting and transacting over USB cable. The minimum required Solo software version that supports the USB mode is 3.3.17.2.

If this version (3.3.17.2) is not yet available on your Solo when connected via Bluetooth, you can switch it to standalone mode (Menu -> Connection -> WiFi), login directly on the Solo, and update it to the latest version.

Solo USB is under beta phase which means that the feature still requires some optimization to ensure full stability.

Known limitations: currently, if the USB cable is unplugged, the USB permission on the mobile device will need to be regranted. As of now, Solo is not able to wake up automatically from sleep mode. A connection needs to be reestablished from
