Step by Step Guide to Building a Zoho Bookings API Integration in Go

Introduction

Hey there, fellow Go enthusiast! Ready to dive into the world of Zoho Bookings API? You're in for a treat. We're going to walk through building a robust integration that'll have you scheduling like a pro in no time. Buckle up!

Prerequisites

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

• Go installed (you're a Gopher, right?)
• A Zoho Bookings account (if not, go grab one!)
• API credentials (your golden ticket to the Zoho world)

Setting up the project

Let's get this show on the road:

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

Now, let's grab the essentials:

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

Authentication

First things first, let's get you authenticated:

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

func getAccessToken() (string, error) {
    // Implement OAuth 2.0 flow here
    // Return access token
}

Pro tip: Don't forget to implement token refresh. Your future self will thank you!

Basic API Requests

Let's start with the basics:

client := resty.New()

resp, err := client.R().
    SetAuthToken(accessToken).
    Get("https://bookings.zoho.com/api/v1/json/availableslots")

if err != nil {
    // Handle error
}

// Process response

Core Functionalities

Now for the meat and potatoes:

Fetching available time slots

func getAvailableSlots(date string) ([]Slot, error) {
    // Implement API call
    // Parse response
    // Return slots
}

Creating a booking

func createBooking(slot Slot, customerInfo CustomerInfo) (Booking, error) {
    // Implement API call
    // Parse response
    // Return booking details
}

You've got the idea. Implement updating and canceling in a similar fashion.

Error Handling

Don't let errors catch you off guard:

if resp.StatusCode() != 200 {
    // Parse error response
    // Handle specific error codes
}

And remember, when at first you don't succeed, try, try again (with exponential backoff, of course).

Advanced Features

Ready to level up? Let's talk webhooks and batch operations.

For webhooks:

http.HandleFunc("/webhook", func(w http.ResponseWriter, r *http.Request) {
    // Process incoming webhook data
})

Testing

Test, test, and test again:

func TestCreateBooking(t *testing.T) {
    // Mock API responses
    // Test your function
    // Assert results
}

Performance Optimization

Cache like there's no tomorrow, but respect rate limits like they're the law (because they are).

Deployment Considerations

Keep those secrets secret:

os.Getenv("ZOHO_CLIENT_ID")

And log like your app's life depends on it (because it kind of does).

Conclusion

And there you have it! You're now armed and dangerous with Zoho Bookings API integration skills. Remember, the API docs are your best friend, and practice makes perfect. Now go forth and schedule like a boss!

Happy coding, Gophers! 🐹✨
