Message:

I am trying to implement myPOS (https://www.mypos.eu/) with PHP with API and flutter.
Basically I want to strike API call by the Laravel from flutter app to MYPOS gateway.

I have gone through the official documents with this link. The OAuth API as per this link implemented with PHP but not able to get the results.
I have created the developer account, added the client_id, client_secrets at the required place, followed all the given steps in official document, but still not able to get the required and expected results.

It seems, at some point, the official document is missing some steps with example for the implementation.

It would be great if one can provide an example.

My Answer:
To integrate MyPOS Payment Gateway with PHP Laravel via API, you can follow these steps:

1. Create a developer account on MyPOS and obtain your client_id and client_secret.
2. Install Guzzle HTTP client in your Laravel project by running the following command:
bash
composer require guzzlehttp/guzzle

3. Create a new controller in your Laravel project to handle the API requests. For example, you can create a MyPOSController with a method like `makePayment`:
php
namespace App\Http\Controllers;

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

class MyPOSController extends Controller
{
public function makePayment(Request $request)
{
$client = new Client();

$response = $client->post('https://api.mypos.com/v1/oauth/token', [
'form_params' => [
'grant_type' => 'client_credentials',
'client_id' => 'YOUR_CLIENT_ID',
'client_secret' => 'YOUR_CLIENT_SECRET',
]
]);

$accessToken = json_decode($response->getBody())->access_token;

$response = $client->post('https://api.mypos.com/v1/payments', [
'headers' => [
'Authorization' => 'Bearer ' . $accessToken,
'Content-Type' => 'application/json',
],
'json' => [
'amount' => $request->amount,
'currency' => $request->currency,
// Add other payment details here
]
]);

return $response->getBody();
}
}

4. Create a route in your `routes/web.php` file to handle the API request:
php
Route::post('/make-payment', 'MyPOSController@makePayment');

5. In your Flutter app, make a POST request to your Laravel endpoint `/make-payment` with the required payment details:
dart
import 'package:http/http.dart' as http;

Future makePayment() async {
var url = 'http://your-laravel-app.com/make-payment';
var response = await http.post(url, body: {
'amount': '10.00',
'currency': 'USD',
// Add other payment details here
});

print(response.body);
}

6. Make sure to replace `YOUR_CLIENT_ID` and `YOUR_CLIENT_SECRET` with your actual credentials in the Laravel controller.

By following these steps, you should be able to integrate MyPOS Payment Gateway with PHP Laravel via API and make payment requests from your Flutter app.
