For Laravel 5.0 and above

## Getting Started
To get started add the following package to your `composer.json` file using this command.

    composer require paytm/js-checkout

## Configuring
**Note: For Laravel 5.5 and above auto-discovery takes care of below configuration.**

When composer installs Laravel Paytm Wallet library successfully, register the `Paytm\JsCheckout\PaytmServiceProvider` in your `config/app.php` configuration file.

```php
'providers' => [
    // Other service providers...
    Paytm\JsCheckout\PaytmServiceProvider::class,
],
```
Also, add the `Paytm` facade to the `aliases` array in your `app` configuration file:

```php
'aliases' => [
    // Other aliases
    'Paytm' => Paytm\JsCheckout\Facades\Paytm::class,
],
```
#### Add the paytm credentials to the `.env` file
```bash
PAYTM_ENVIRONMENT=staging
PAYTM_MERCHANT_ID=YOUR_MERCHANT_ID_HERE
PAYTM_MERCHANT_KEY=YOUR_SECRET_KEY_HERE
PAYTM_MERCHANT_WEBSITE=YOUR_MERCHANT_WEBSITE
PAYTM_CHANNEL=YOUR_CHANNEL_HERE
PAYTM_INDUSTRY_TYPE=YOUR_INDUSTRY_TYPE_HERE
```


#### One more step to go....
On your `config/services.php` add the following configuration

```php
'paytm' => [
        'env' => env('PAYTM_ENVIRONMENT'), // values : (staging | production)
        'merchant_id' => env('PAYTM_MERCHANT_ID'),
        'merchant_key' => env('PAYTM_MERCHANT_KEY'),
        'merchant_website' => env('PAYTM_MERCHANT_WEBSITE'),
        'channel' => env('PAYTM_CHANNEL'),
        'industry_type' => env('PAYTM_INDUSTRY_TYPE'),
],
```
Note : All the credentials mentioned are provided by Paytm after signing up as merchant.

#### Laravel 7 Changes
Our package is compatible with Laravel 7 but same_site setting is changed in default Laravel installation, make sure you change `same_site` to `null` in `config/session.php` or callback won't include cookies and you will be logged out when a payment is completed

```php
<?php

use Illuminate\Support\Str;

return [
  /...
  'same_site' => null,
];
```

## Usage


### Making a transaction
```
<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Paytm;

class PaytmController extends Controller
{
    // display a form for payment
    public function initiate()
    {
          return view('paytm');
    }

    public function pay(Request $request)
    {
        $amount = 1; //Amount to be paid

        $userData = [
            'name' => $request->name, // Name of user
            'mobile' => $request->mobile, //Mobile number of user
            'email' => $request->email, //Email of user
            'fee' => $amount,
            'order_id' => rand(1,1000) //Order id
        ];

        $payment = Paytm::with('receive');

        $payment->prepare([
            'order' => $userData['order_id'], 
            'user' => 1,
            'mobile_number' => $userData['mobile'],
            'email' => $userData['email'], // your user email address
            'amount' => $amount, // amount will be paid in INR.
            'callback_url' => route('status') // callback URL
        ]);
        $response =  $payment->receive();  // initiate a new payment
        return $response;
    }

    public function paymentCallback()
    {
        $transaction = Paytm::with('receive');

        $response = $transaction->response();
        
        $order_id = $transaction->getOrderId(); // return a order id
      
        $transaction->getTransactionId(); // return a transaction id
        // update the db data as per result from api call
        if ($transaction->isSuccessful()) {
            return redirect(route('initiate.payment'))->with('message', "Your payment is successfull.");

        } else if ($transaction->isFailed()) {
            return redirect(route('initiate.payment'))->with('message', "Your payment is failed.");
            
        } else if ($transaction->isOpen()) {
             return redirect(route('initiate.payment'))->with('message', "Your payment is processing.");
        }
        $transaction->getResponseMessage(); //Get Response Message If Available
    }
}

```

### Define routes
```
Route::get('/initiate','PaytmController@initiate')->name('initiate.payment');
Route::post('/payment','PaytmController@pay')->name('make.payment');
Route::post('/payment/status', 'PaytmController@paymentCallback')->name('status');

```
Important: The `callback_url` must not be csrf protected [Check out here to how to do that](https://laracasts.com/discuss/channels/general-discussion/l5-disable-csrf-middleware-on-certain-routes)
