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

Introduction

Hey there, fellow Go enthusiast! Ready to dive into the world of Loomly API integration? You're in for a treat. Loomly's API is a powerful tool for managing social media content, and we're about to harness that power with the elegance of Go. Let's get cracking!

Prerequisites

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

• Go installed (I know, obvious, right?)
• Loomly API credentials (if you don't have these, hop over to Loomly and sort that out)
• Your favorite Go IDE or text editor

Setting up the project

Let's start with the basics:

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

Easy peasy! We're off to a great start.

Authentication

Loomly uses OAuth2, so let's set that up:

import (
    "golang.org/x/oauth2"
)

func getClient() *http.Client {
    config := &oauth2.Config{
        ClientID:     os.Getenv("LOOMLY_CLIENT_ID"),
        ClientSecret: os.Getenv("LOOMLY_CLIENT_SECRET"),
        Endpoint: oauth2.Endpoint{
            AuthURL:  "https://api.loomly.com/oauth/authorize",
            TokenURL: "https://api.loomly.com/oauth/token",
        },
    }

    token := &oauth2.Token{
        AccessToken: os.Getenv("LOOMLY_ACCESS_TOKEN"),
    }

    return config.Client(context.Background(), token)
}

Pro tip: Keep those credentials safe! Use environment variables or a secure config management system.

Making API requests

Now, let's create a client that handles rate limiting and retries:

import (
    "github.com/hashicorp/go-retryablehttp"
    "time"
)

func newLoomlyClient() *retryablehttp.Client {
    client := retryablehttp.NewClient()
    client.RetryMax = 3
    client.RetryWaitMin = 1 * time.Second
    client.RetryWaitMax = 5 * time.Second
    client.HTTPClient = getClient()
    return client
}

Implementing key Loomly API endpoints

Let's implement a few key endpoints:

func fetchCalendars(client *retryablehttp.Client) ([]Calendar, error) {
    // Implementation here
}

func createPost(client *retryablehttp.Client, post Post) error {
    // Implementation here
}

func uploadAsset(client *retryablehttp.Client, asset Asset) error {
    // Implementation here
}

Error handling and logging

Don't forget to handle those errors gracefully:

import (
    "github.com/sirupsen/logrus"
)

func handleError(err error) {
    if err != nil {
        logrus.WithError(err).Error("An error occurred")
        // Additional error handling logic
    }
}

Testing the integration

Testing is crucial, folks! Here's a quick example:

func TestFetchCalendars(t *testing.T) {
    client := newLoomlyClient()
    calendars, err := fetchCalendars(client)
    assert.NoError(t, err)
    assert.NotEmpty(t, calendars)
}

Best practices and optimization

To squeeze out every bit of performance:

1. Implement caching for frequently accessed data
2. Use goroutines for concurrent requests (but be mindful of rate limits!)

Conclusion

And there you have it! You've just built a solid Loomly API integration in Go. From here, you can expand on this foundation to create powerful social media management tools. The sky's the limit!

Remember, the best code is code that's constantly evolving. Keep refining, keep learning, and most importantly, keep coding. You've got this!
