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

Introduction

Hey there, fellow Go enthusiast! Ready to dive into the world of CompanyCam API integration? You're in for a treat. CompanyCam's API is a powerful tool that lets you tap into their photo-centric project management platform. In this guide, we'll walk through building a solid integration that'll have you manipulating projects and photos like a pro.

Prerequisites

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

• Go installed (I know, obvious, right?)
• CompanyCam API credentials (grab these from your account)
• Your favorite Go IDE or text editor

Setting up the project

Let's kick things off by setting up our project:

mkdir companycam-integration
cd companycam-integration
go mod init companycam-integration

Easy peasy! Now we're ready to start coding.

Authentication

CompanyCam uses OAuth 2.0, so let's tackle that first:

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

func getClient() *http.Client {
    config := &oauth2.Config{
        ClientID:     "YOUR_CLIENT_ID",
        ClientSecret: "YOUR_CLIENT_SECRET",
        Endpoint:     oauth2.Endpoint{
            AuthURL:  "https://app.companycam.com/oauth/authorize",
            TokenURL: "https://app.companycam.com/oauth/token",
        },
    }

    token := &oauth2.Token{
        AccessToken: "YOUR_ACCESS_TOKEN",
    }

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

Pro tip: In a real-world scenario, you'd want to implement the full OAuth flow and securely store those tokens.

Making API requests

Time to create our API client:

type CompanyCamClient struct {
    BaseURL    string
    HTTPClient *http.Client
}

func NewCompanyCamClient(httpClient *http.Client) *CompanyCamClient {
    return &CompanyCamClient{
        BaseURL:    "https://api.companycam.com/v2",
        HTTPClient: httpClient,
    }
}

func (c *CompanyCamClient) 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("Content-Type", "application/json")
    return c.HTTPClient.Do(req)
}

Implementing key CompanyCam features

Let's implement some core features:

func (c *CompanyCamClient) GetProjects() ([]Project, error) {
    resp, err := c.doRequest("GET", "/projects", nil)
    // Handle response and unmarshal JSON
}

func (c *CompanyCamClient) UploadPhoto(projectID string, photo []byte) error {
    // Implement photo upload logic
}

func (c *CompanyCamClient) AddTag(photoID, tagName string) error {
    // Implement tag addition logic
}

Error handling and logging

Don't forget to implement robust error handling and logging. Trust me, your future self will thank you!

import "log"

func (c *CompanyCamClient) logError(err error) {
    log.Printf("CompanyCam API error: %v", err)
}

Testing the integration

Writing tests is crucial. Here's a quick example:

func TestGetProjects(t *testing.T) {
    client := NewCompanyCamClient(getClient())
    projects, err := client.GetProjects()
    if err != nil {
        t.Fatalf("Failed to get projects: %v", err)
    }
    // Add more assertions
}

Best practices and optimization

To take your integration to the next level:

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

Conclusion

And there you have it! You've just built a solid CompanyCam API integration in Go. Remember, this is just the beginning. There's always room to expand and improve your integration.

Keep coding, stay curious, and don't forget to document your work. Your future self (and your team) will appreciate it. Happy integrating!
