Example

package main

    "fmt"
    "log"

    "github.com/hetznercloud/hcloud-go/v2/hcloud"
)

func main() {
    client := hcloud.NewClient(hcloud.WithToken("token"))

    server, _, err := client.Server.GetByID(context.Background(), 1)
    if err != nil {
        log.Fatalf("error retrieving server: %s\n", err)
    }
    if server != nil {
        fmt.Printf("server 1 is called %q\n", server.Name)
    } else {
        fmt.Println("server 1 not found")
    }
}

Upgrading

Support

• v2 is actively maintained by Hetzner Cloud
• v1 is unsupported since February 2025.

From v1 to v2

Version 2.0.0 was published because we changed the datatype of all ID fields from int to int64.

To migrate to the new version, replace all your imports to reference the new module path:

 import (
-  "github.com/hetznercloud/hcloud-go/hcloud"
+  "github.com/hetznercloud/hcloud-go/v2/hcloud"
 )

When you compile your code, it will show any invalid usages of int in your code that you need to fix. We commonly found these changes while updating our integrations:

• strconv.Atoi(idString) (parsing integers) needs to be replaced by strconv.ParseInt(idString, 10, 64)
• strconv.Itoa(id) (formatting integers) needs to be replaced by strconv.FormatInt(id, 10)

Go Version Support

The library supports the latest two Go minor versions, e.g. at the time Go 1.19 is released, it supports Go 1.18 and 1.19.

This matches the official Go Release Policy.

When the minimum required Go version is changed, it is announced in the release notes for that version.
