Set up Go SDK

Install the package

If you are using the standard Go modules system, import the SDK packages in your code and go build will automatically download them. The SDK and its dependencies are modules.
Alternatively, you can run the following command:

Shell

$ go get github.com/launchdarkly/go-server-sdk/v7

Initialize the SDK

Go SDK initialization

1 package main
2 
3 import (
4 	"fmt"
5 	"os"
6 	"time"
7 
8 	ld "github.com/launchdarkly/go-server-sdk/v7"
9 )
10 
11 func main() {
12 	// This is your LaunchDarkly SDK key.
13 	// Never hardcode your SDK key in production.
14 	ldClient, _ := ld.MakeClient("YOUR_SDK_KEY", 5*time.Second)
15 	if ldClient.Initialized() {
16 		fmt.Printf("SDK successfully initialized!")
17 	} else {
18 		fmt.Printf("SDK failed to initialize")
19 		os.Exit(1)
20 	}
21 
22 	// For onboarding purposes only we flush events as soon as
23 	// possible so we quickly detect your connection.
24 	// You don't have to do this in practice because events are automatically flushed.
25 	ldClient.Flush()
26 }

Finding your SDK credentials

You can find your server-side SDK keys, mobile keys, and client-side ID on the SDK keys page under Settings.

To learn more, read Initialize the client in the Go SDK reference guide.
