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

Introduction

Hey there, fellow Go enthusiast! Ready to supercharge your app with some video messaging goodness? Let's dive into building a Bonjoro API integration. Bonjoro's API lets you send personalized video messages, manage campaigns, and handle contacts programmatically. Exciting stuff, right?

Prerequisites

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

• Go installed (I know you probably do, but just checking!)
• Bonjoro API credentials (grab 'em from your Bonjoro dashboard)

Setting up the project

Let's kick things off:

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

We'll need a HTTP client, but Go's standard library has us covered. No extra dependencies required!

Authentication

Bonjoro uses API key authentication. Let's create a client:

type BonjoroClient struct {
    APIKey string
    BaseURL string
    HTTPClient *http.Client
}

func NewBonjoroClient(apiKey string) *BonjoroClient {
    return &BonjoroClient{
        APIKey: apiKey,
        BaseURL: "https://api.bonjoro.com/v2",
        HTTPClient: &http.Client{},
    }
}

Making API requests

Time to make some requests! Here's a helper method:

func (c *BonjoroClient) doRequest(method, path string, body io.Reader) (*http.Response, error) {
    req, err := http.NewRequest(method, c.BaseURL+path, body)
    if err != nil {
        return nil, err
    }
    req.Header.Set("Authorization", "Bearer "+c.APIKey)
    req.Header.Set("Content-Type", "application/json")
    return c.HTTPClient.Do(req)
}

Implementing key Bonjoro API endpoints

Let's implement sending a video message:

func (c *BonjoroClient) SendVideoMessage(recipient, message string) error {
    payload := struct {
        Recipient string `json:"recipient"`
        Message   string `json:"message"`
    }{
        Recipient: recipient,
        Message:   message,
    }
    jsonBody, _ := json.Marshal(payload)
    _, err := c.doRequest("POST", "/messages", bytes.NewBuffer(jsonBody))
    return err
}

You can implement other endpoints like retrieving campaign data or managing contacts in a similar fashion.

Error handling and response parsing

Always check for errors and parse responses:

resp, err := c.doRequest("GET", "/campaigns", nil)
if err != nil {
    return nil, err
}
defer resp.Body.Close()

if resp.StatusCode != http.StatusOK {
    return nil, fmt.Errorf("API request failed with status code: %d", resp.StatusCode)
}

var campaigns []Campaign
if err := json.NewDecoder(resp.Body).Decode(&campaigns); err != nil {
    return nil, err
}

Building a simple CLI tool

Let's wrap our client in a CLI:

func main() {
    apiKey := os.Getenv("BONJORO_API_KEY")
    client := NewBonjoroClient(apiKey)

    if len(os.Args) < 2 {
        fmt.Println("Usage: ./bonjoro-cli <command> [args...]")
        os.Exit(1)
    }

    switch os.Args[1] {
    case "send":
        if len(os.Args) != 4 {
            fmt.Println("Usage: ./bonjoro-cli send <recipient> <message>")
            os.Exit(1)
        }
        err := client.SendVideoMessage(os.Args[2], os.Args[3])
        if err != nil {
            fmt.Printf("Error sending message: %v\n", err)
        } else {
            fmt.Println("Message sent successfully!")
        }
    // Add more commands here
    default:
        fmt.Println("Unknown command")
        os.Exit(1)
    }
}

Testing the integration

Don't forget to test! Here's a simple test for our SendVideoMessage function:

func TestSendVideoMessage(t *testing.T) {
    client := NewBonjoroClient("test-api-key")
    err := client.SendVideoMessage("[email protected]", "Hello, World!")
    if err != nil {
        t.Errorf("SendVideoMessage failed: %v", err)
    }
}

Best practices and optimization

Remember to implement rate limiting to stay within API limits. You could use a package like golang.org/x/time/rate for this.

For frequently accessed data, consider implementing a caching layer to reduce API calls and improve performance.

Conclusion

And there you have it! You've just built a Bonjoro API integration in Go. You can now send personalized video messages programmatically - how cool is that?

From here, you could expand the CLI to cover more API endpoints, build a web interface, or integrate this into your existing Go applications. The possibilities are endless!

Remember, the key to mastering API integrations is practice and exploration. So go forth and code! Happy Go-ing!
