Introduction

Hey there, fellow developer! Ready to dive into the world of Zoho Bookings API integration? You're in for a treat. This guide will walk you through the process of building a robust integration in C#. We'll cover everything from authentication to advanced features, so buckle up!

Prerequisites

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

A Zoho account with API credentials
Your favorite C# development environment
NuGet packages: Newtonsoft.Json and RestSharp

Got all that? Great! Let's get coding.

Authentication

First things first, let's get you authenticated:

public async Task<string> GetAccessToken()
{
    // Your authentication logic here
    // Don't forget to implement token refresh!
}

Pro tip: Store your refresh token securely and implement an automatic refresh mechanism. Your future self will thank you.

Basic API Setup

Let's create a base API client class:

public class ZohoBookingsClient
{
    private readonly string _baseUrl = "https://bookings.zoho.com/api/v1";
    private readonly RestClient _client;

    public ZohoBookingsClient(string accessToken)
    {
        _client = new RestClient(_baseUrl);
        _client.AddDefaultHeader("Authorization", $"Bearer {accessToken}");
    }

    // Add methods for API calls here
}

Implementing Core Functionalities

Now for the fun part! Let's implement some key features:

Fetching Available Time Slots

public async Task<List<TimeSlot>> GetAvailableTimeSlots(string serviceId, DateTime date)
{
    var request = new RestRequest($"services/{serviceId}/availableslots", Method.GET);
    request.AddQueryParameter("date", date.ToString("yyyy-MM-dd"));

    var response = await _client.ExecuteAsync<List<TimeSlot>>(request);
    return response.Data;
}

Creating a Booking

public async Task<Booking> CreateBooking(BookingRequest bookingRequest)
{
    var request = new RestRequest("bookings", Method.POST);
    request.AddJsonBody(bookingRequest);

    var response = await _client.ExecuteAsync<Booking>(request);
    return response.Data;
}

You've got the idea! Implement similar methods for retrieving, updating, and canceling bookings.

Error Handling and Logging

Don't let those pesky errors catch you off guard:

try
{
    // Your API call here
}
catch (Exception ex)
{
    _logger.LogError($"Error occurred: {ex.Message}");
    // Handle the error gracefully
}

Advanced Features

Feeling adventurous? Try implementing webhooks for real-time updates or add rate limiting to your requests. Your API integration will be unstoppable!

Testing

Remember, a well-tested integration is a happy integration:

[Fact]
public async Task GetAvailableTimeSlots_ReturnsValidData()
{
    // Your test logic here
}

Best Practices and Optimization

Cache frequently accessed data to reduce API calls
Use asynchronous programming for better performance
Keep your code clean and modular

Conclusion

And there you have it! You've just built a solid Zoho Bookings API integration in C#. From authentication to advanced features, you're now equipped to handle bookings like a pro. The possibilities are endless – go forth and create amazing booking experiences!
