I have implemented PayPal (PHP, Laravel) and there is some issue coming while payment. I am getting the following exception in the live.
PayPal\Exception\PayPalInvalidCredentialException: Credential not found for default user. Please make sure your configuration/APIContext has credential information in /var/www/project/project-files/vendor/paypal/rest-api-sdk-php/lib/PayPal/Core/PayPalCredentialManager.php
I have checked this and other similar problems with the same issue but those didn't helped, i am still missing something. A little help or guidance will be helpful.
The scenario is: Once a user request for Payment, the admin approves it, the payment will be processed.
For this purpose a Laravel Job is created and code for the following Job is:
namespace Test\Jobs;
use Illuminate\Bus\Queueable;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Queue\SerializesModels;
use PayPal;
use Test\Models\Transaction;
class ProcessPayout implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
/**
* @var Transaction
*/
protected $transaction;
/**
* Create a new job instance.
*
* @param Transaction $transaction
*/
public function __construct(Transaction $transaction) {
$this->transaction = $transaction;
}
/**
* Execute the job.
*
* @return void
*/
public function handle() {
try {
\Log::info($this->transaction); // I am getting all the data in this to be processed from Transaction Model
$response = PayPal::makePayoutEnvironment()
->setPayoutEmailSubject($this->transaction->sender_batch_id)
->setPayoutItem($this->transaction->receiver, $this->transaction->amount, $this->transaction->sender_item_id)
->makePayout();
if(empty($response)){
throw new \Exception();
}
}catch(\Exception $e){
\Log::info($e);
}
}
}
The PayPal.php is as follows:
namespace Test\PayPal;
use PayPal\Api\Currency;
use PayPal\Api\Payout;
use PayPal\Api\PayoutItem;
use PayPal\Api\PayoutSenderBatchHeader;
use PayPal\Rest\ApiContext;
use ResultPrinter;
class PayPal
{
/**
* @var ApiContext
*/
protected $context;
/**
* @var Payout
*/
protected $payout;
/**
* @var PayoutSenderBatchHeader
*/
protected $senderHeader;
/**
* PayPal constructor.
*/
public function __construct()
{
$this->context = app('PayPalContext');
}
/**
* Create payout environment.
*/
public function makePayoutEnvironment()
{
$this->payout = new Payout();
$this->senderHeader = new PayoutSenderBatchHeader();
return $this;
}
/**
* Set payout sender email subject.
*
* @param $senderId
* @param null $subject
*
* @return $this
*/
public function setPayoutEmailSubject($senderId, $subject = null)
{
$this->senderHeader->setSenderBatchId($senderId)
->setEmailSubject($subject ?: config('mail.subject_prefix') . 'Payout accepted.');
$this->payout->setSenderBatchHeader($this->senderHeader);
return $this;
}
/**
* Set the payout item with receiver and amount of.
*
* @param $receiverEmail
* @param $amount
*
* @param $itemId
*
* @return $this
*/
public function setPayoutItem($receiverEmail, $amount, $itemId)
{
$item = (new PayoutItem())->setRecipientType('Email')
->setNote($this->senderHeader->getEmailSubject())
->setReceiver($receiverEmail)
->setSenderItemId($itemId)
->setAmount(new Currency(sprintf('{
"value":"%s",
"currency":"%s"
}', $amount, config('currency.fallback'))));
$this->payout->addItem($item);
return $this;
}
/**
* Make payout for recipient.
*
* @return bool|\PayPal\Api\PayoutBatch
*/
public function makePayout()
{
try {
$output = $this->payout->create(['sync_mod' => false], $this->context);
} catch (\Exception $ex) {
\Log::info($ex);
return false;
}
return $output;
}
}
And code for the PayPalServiceProvider is as follows:
namespace Test\Providers;
use Illuminate\Support\ServiceProvider;
use PayPal\Auth\OAuthTokenCredential;
use PayPal\Rest\ApiContext;
use Test\PayPal\PayPal;
class PayPalServiceProvider extends ServiceProvider
{
public function boot() {
}
public function register()
{
$this->app->singleton('PayPalContext', function ($app) {
$config = array('mode' => 'live');
$apiContext = new ApiContext(
new OAuthTokenCredential(
config('services.paypal.client_id'),// ClientID
config('services.paypal.client_secret')// ClientSecret
)
);
$apiContext->setConfig($config);
return $apiContext;
});
$this->app->singleton('PayPal', function ($app) {
return new PayPal();
});
}
/**
* Get the services provided by the provider.
*
* @return array
*/
public function provides(){
return [ 'PayPal' ];
}
}
