How To Connect Laravel to ChatGPT API

Step 1: Create a new Laravel project

Assuming you have Laravel installed on your computer, create a new project by running the following command:

composer create-project laravel/laravel chatgpt

Step 2: Install Guzzle HTTP client

Guzzle is a PHP HTTP client that makes it easy to send HTTP requests and work with APIs. To install it, run the following command:

composer require guzzlehttp/guzzle

Step 3: Get an API key from ChatGPT

To use ChatGPT API, you need an API key. Visit https://beta.openai.com/docs/api-reference/introduction to sign up and get an API key.

Step 4: Create a new controller

In Laravel, controllers are used to handle HTTP requests and return responses. Create a new controller by running the following command:

php artisan make:controller ChatController

Step 5: Add a method to the controller to send a request to ChatGPT API

In the ChatController class, add a method that sends a request to ChatGPT API using Guzzle HTTP client. Here’s an example:

namespace App\Http\Controllers;

use GuzzleHttp\Client;
use Illuminate\Http\Request;

class ChatController extends Controller
{
    public function chat(Request $request)
    {
        $client = new Client();
        $response = $client->post('https://api.openai.com/v1/engine/davinci-codex/completions', [
            'headers' => [
                'Content-Type' => 'application/json',
                'Authorization' => 'Bearer ' . env('OPENAI_API_KEY'),
            ],
            'json' => [
                'prompt' => $request->input('message'),
                'temperature' => 0.7,
                'max_tokens' => 60,
                'top_p' => 1,
                'n' => 1,
                'stop' => ['\n'],
            ],
        ]);
        $result = json_decode($response->getBody()->getContents(), true);
        return response()->json($result['choices'][0]['text']);
    }
}
