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

Introduction

Hey there, fellow developer! Ready to dive into the world of Kajabi API integration with Go? You're in for a treat. Kajabi's API is a powerful tool that lets you tap into their platform's functionality, and Go's simplicity and efficiency make it a perfect match. Let's get cracking!

Prerequisites

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

• Go installed (you're a pro, so I'm sure you do)
• A Kajabi account with API credentials
• Your favorite code editor

Oh, and coffee. Lots of coffee.

Setting up the project

Let's kick things off:

mkdir kajabi-integration
cd kajabi-integration
go mod init github.com/yourusername/kajabi-integration

Now, let's grab the packages we'll need:

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

Authentication

Alright, time to get those API keys. Head over to your Kajabi account, navigate to the API section, and grab your keys. Don't share them with anyone (not even your rubber duck)!

Now, let's set up authentication:

package main

import (
    "github.com/go-resty/resty/v2"
)

const (
    baseURL = "https://kajabi.com/api/v1"
)

func newClient(apiKey string) *resty.Client {
    return resty.New().
        SetBaseURL(baseURL).
        SetHeader("Authorization", "Bearer "+apiKey)
}

Making API requests

Let's make our first request. How about fetching some products?

func getProducts(client *resty.Client) ([]byte, error) {
    resp, err := client.R().Get("/products")
    if err != nil {
        return nil, err
    }
    return resp.Body(), nil
}

Easy peasy, right? Now, let's try a POST request to create an offer:

func createOffer(client *resty.Client, offer map[string]interface{}) ([]byte, error) {
    resp, err := client.R().
        SetBody(offer).
        Post("/offers")
    if err != nil {
        return nil, err
    }
    return resp.Body(), nil
}

Implementing key Kajabi API endpoints

You've got the hang of it now. Let's implement a few more endpoints:

func getPipelines(client *resty.Client) ([]byte, error) {
    // Implementation here
}

func getMembers(client *resty.Client) ([]byte, error) {
    // Implementation here
}

Error handling and rate limiting

Don't forget to handle those errors and respect rate limits. Kajabi will thank you (and so will your future self):

func makeRequest(client *resty.Client, method, endpoint string) ([]byte, error) {
    resp, err := client.R().Execute(method, endpoint)
    if err != nil {
        return nil, err
    }
    
    if resp.StatusCode() == 429 {
        // Handle rate limiting
        time.Sleep(5 * time.Second)
        return makeRequest(client, method, endpoint)
    }
    
    return resp.Body(), nil
}

Data processing and storage

Now that we're getting data, let's do something with it:

type Product struct {
    ID   string `json:"id"`
    Name string `json:"name"`
    // Add more fields as needed
}

func parseProducts(data []byte) ([]Product, error) {
    var products []Product
    err := json.Unmarshal(data, &products)
    return products, err
}

Building a simple CLI tool

Let's wrap this up in a neat CLI package:

package main

import (
    "fmt"
    "os"
)

func main() {
    if len(os.Args) < 2 {
        fmt.Println("Usage: kajabi-cli <command>")
        os.Exit(1)
    }

    apiKey := os.Getenv("KAJABI_API_KEY")
    client := newClient(apiKey)

    switch os.Args[1] {
    case "products":
        // Handle products command
    case "offers":
        // Handle offers command
    // Add more commands as needed
    default:
        fmt.Println("Unknown command")
        os.Exit(1)
    }
}

Testing the integration

Don't forget to test! Here's a quick example:

func TestGetProducts(t *testing.T) {
    client := newClient("test-api-key")
    products, err := getProducts(client)
    if err != nil {
        t.Fatalf("Expected no error, got %v", err)
    }
    // Add more assertions
}

Best practices and optimization

Keep your code clean and modular. Use interfaces for better testability. And remember, premature optimization is the root of all evil (but don't be afraid to profile and optimize when needed).

Conclusion

And there you have it! You've just built a Kajabi API integration in Go. Pretty cool, huh? Remember, this is just the beginning. There's so much more you can do with the Kajabi API. Keep exploring, keep coding, and most importantly, keep having fun!
