The IONOS Cloud SDK for GO provides you with access to the IONOS Cloud API. The client library supports both simple and complex requests. It is designed for developers who are building applications in GO . The SDK for GO wraps the IONOS Cloud API. All API operations are performed over SSL and authenticated using your IONOS Cloud portal credentials. The API can be accessed within an instance running in IONOS Cloud or directly over the Internet from any application that can send an HTTPS request and receive an HTTPS response.

Getting Started

An IONOS account is required for access to the Cloud API; credentials from your registration are used to authenticate against the IONOS Cloud API.


Install the Go language from from the official Go installation guide.

The GOPATH environment variable specifies the location of your Go workspace. It is likely the only environment variable you will have to set when developing Go code. This is an example of pointing to a workspace configured under your home directory:

mkdir -p ~/go/bin
export GOPATH=~/go
export GOBIN=$GOPATH/bin

The following go command will download sdk-go to your configured GOPATH:

go get ""

The source code of the package will be located here:


Create main package file example.go:

package main
import (
func main() {

Include the IONOS Cloud SDK for Go under the list of imports.



The username and password or the authentication token can be manually specified when initializing the SDK client:

client := ionoscloud.NewAPIClient(ionoscloud.NewConfiguration(username, password, token))

Environment variables can also be used; the SDK uses the following variables:

  • IONOS_USERNAME - to specify the username used to login

  • IONOS_PASSWORD - to specify the password

  • IONOS_TOKEN - if an authentication token is being used

In this case, the client configuration must be initialized using NewConfigurationFromEnv()

client := ionoscloud.NewAPIClient(ionoscloud.NewConfigurationFromEnv())

Warning: Make sure to follow the Information Security Best Practices when using credentials within your code or storing them in a file.


Many of the List or Get operations will accept an optional depth argument. Setting this to a value between 0 and 5 affects the amount of data that is returned. The details returned vary depending on the resource being queried, but it generally follows this pattern. By default, the SDK sets the depth argument to the maximum value.




Only direct properties are included. Children are not included.


Direct properties and children's references are returned.


Direct properties and children's properties are returned.


Direct properties, children's properties, and descendants' references are returned.


Direct properties, children's properties, and descendants' properties are returned.


Returns all available properties.


The operations will also accept an optional pretty argument. Setting this to a value of true or false controls whether the response is pretty-printed (with indentation and new lines). By default, the SDK sets the pretty argument to true.

Changing the base URL

Base URL for the HTTP operation can be changed by using the following function:


Feature Reference
