Step by Step Guide to Building a Memberstack API Integration in Go

Introduction

Hey there, Go enthusiast! Ready to supercharge your app with Memberstack's powerful user management features? Let's dive into building a robust API integration that'll have you managing members like a pro in no time.

Prerequisites

Before we jump in, make sure you've got:

• Go installed (you're a Gopher, right?)
• A Memberstack account with an API key
• Your Go and RESTful API skills polished

Setting up the project

Let's kick things off:

mkdir memberstack-integration
cd memberstack-integration
go mod init memberstack-integration

Now, let's grab the HTTP client we'll be using:

go get -u github.com/go-resty/resty/v2

Authentication

First things first, let's keep that API key safe:

apiKey := os.Getenv("MEMBERSTACK_API_KEY")
if apiKey == "" {
    log.Fatal("MEMBERSTACK_API_KEY not set")
}

Pro tip: Use environment variables to keep your secrets... well, secret!

Basic API Requests

Time to make some magic happen. Let's fetch a member's details:

client := resty.New()
resp, err := client.R().
    SetAuthToken(apiKey).
    Get("https://api.memberstack.io/v1/members/{memberId}")

if err != nil {
    log.Fatalf("Error fetching member: %v", err)
}

fmt.Println(resp.String())

Creating a new member? Easy peasy:

resp, err := client.R().
    SetAuthToken(apiKey).
    SetBody(map[string]interface{}{
        "email": "[email protected]",
        "password": "securepassword123",
    }).
    Post("https://api.memberstack.io/v1/members")

Handling Responses

Let's make sense of those JSON responses:

var member Member
err = json.Unmarshal(resp.Body(), &member)
if err != nil {
    log.Fatalf("Error parsing response: %v", err)
}

Always be prepared for errors:

if resp.StatusCode() != 200 {
    log.Fatalf("API error: %s", resp.String())
}

Advanced Features

Webhooks? We've got you covered:

http.HandleFunc("/webhook", func(w http.ResponseWriter, r *http.Request) {
    // Handle the webhook payload
})

Testing

Test like you mean it:

func TestGetMember(t *testing.T) {
    // Mock the API response
    // Test your GetMember function
}

Best Practices

• Respect rate limits: Use exponential backoff for retries
• Cache frequently accessed data to reduce API calls

Conclusion

And there you have it! You're now armed with the knowledge to build a solid Memberstack integration in Go. Remember, the API is your oyster - explore, experiment, and build something awesome!
