Learn how to seamlessly integrate the ChatGPT API into your Laravel 11 application with this comprehensive step-by-step guide. Boost your app’s AI capabilities and enhance user interaction using OpenAI’s powerful API.

What is ChatGPT/OpenAI?

ChatGPT is an advanced language model developed by OpenAI, based on the GPT-4 architecture (as of 2023). It is designed to understand and generate human-like text based on the input it receives. GPT stands for “Generative Pre-trained Transformer,” which is a deep learning model that processes and generates natural language using vast amounts of text data.

How to Integrate ChatGPT API with Laravel 11: A Step-by-Step Guide

• Step 1: Install Laravel
• Step 2: Install openai-php/laravel Package
• Step 3: Create OpenAI Account
• Step 4: Create Route
• Step 5: Create Controller
• Step 6: Create Blade File
• Run Laravel App

Step 1: Install Laravel

To begin, we must obtain the latest version of the Laravel application by executing the command stated below. Open your terminal or command prompt and enter the given command.

composer create-project laravel/laravel example-app

Step 2: Install openai-php/laravel Package

In this step, we need to install openai-php/laravel composer package to use OpenAI API. so let’s run bellow command:

composer require openai-php/laravel

Now, we will publish configuration file using the following command:

php artisan vendor:publish --provider="OpenAI\Laravel\ServiceProvider"

Step 3: Create OpenAI Account

First you need to create Account on OpenAI website.

1. Go to https://platform.openai.com/ you can register there you will get free access $18 credit for next three months.

2. After that go to https://platform.openai.com/account/api-keys and generate the API token.

You can follow the below screenshots:

This screenshot, you need to copy API key and add on your .env file as like the below:

Then add your API KEY to .env file:

.env

OPENAI_API_KEY=api_key...

Step 4: Create Route

now we will create one route for calling our example, so let’s add new route to web.php file as bellow:

routes/web.php

<?php
  
use Illuminate\Support\Facades\Route;
  
use App\Http\Controllers\ChatGPTController;
  
Route::get('/chat-gpt', [ChatGPTController::class, 'index'])->name('chat-gpt.index');

Step 5: Create Controller

in this step, we will create ChatGPTController and write payment logic, so let’s add new route to web.php file as bellow:

app/Http/Controllers/ChatGPTController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Arr;
use OpenAI\Laravel\Facades\OpenAI;

class ChatGPTController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index(Request $request)
    {
        $result = '';

        if ($request->filled('title')) {
            $messages = [
                ['role' => 'user', 'content' => 'suggest me 5 domain names from "'.$request->title.'" topic. simply give me domain names list with 1. 2. 3. 4. 5. '],
            ];

            $result = OpenAI::chat()->create([
                'model' => 'gpt-3.5-turbo',
                'messages' => $messages,
            ]);

            $result = Arr::get($result, 'choices.0.message')['content'] ?? '';
        }

        return view('chatGPT', compact('result'));

    }
}

Step 6: Create Blade File

here, we need to create chatGPT.blade.php file and update following code on it.

resources/views/auth/chatGPT.blade.php

            <div class="card-body"> 
                <form method="GET" action="{{ route('chat-gpt.index') }}">
                    <div class="form-group">
                        <label><strong>Give me your title, I will provide you domains list.</strong></label>
                        <input type="text" name="title" class="form-control" />
                    </div>
                    <div class="form-group mt-2">
                        <button type="submit" class="btn btn-success">Submit</button>
                    </div>
                </form>

                @if(!empty($result))
                    <div class="mt-5">
                        <strong>Result:</strong><br/>
                        {!! nl2br($result) !!}
                    </div>
                @endif

            </div>
        </div>
    </div>
</body>
</html>

Run Laravel App:

All the required steps have been done, now you have to type the given below command and hit enter to run the Laravel app

php artisan serve

Now, Go to your web browser, type the given URL and view the app output:

http://localhost:8000/chat-gpt

Now, you will see the following output:

Now, it’s done…

I hope it can help you…
