Paypal Refund amount using laravel - php

Question

I have successfully implement PayPal with laravel. I am able to make payment using PayPal APIs. Now I want to implement refund from PayPal using laravel. I don't want to make refund from PayPal dashboard but i want to make it done from our admin panel where admin user can see list of payments and link to refund that amount to customer. After successful payment I got Transaction id in response from PayPal. If i use that transaction id to refund then i am not able to do that successfully, and if i copy transaction id from paypal dashboard where all transactions are listed and get detail information of that transaction, then i am able to make refund success. Can anyone tell me how can i get that transaction id using which i can make refund using laravel.

Answer 1

I have to use below code to get actual sale id to refund amount using code not from paypal dashboard
$apiContext = new ApiContext(new OAuthTokenCredential(
"<CLIENT_ID>", "<CLIENT_SCRET_KEY>")
);
$payments = Payment::get($payment_id, $apiContext);
$payments->getTransactions();
$obj = $payments->toJSON();//I wanted to look into the object
$paypal_obj = json_decode($obj);//I wanted to look into the object
$transaction_id = $paypal_obj->transactions[0]->related_resources[0]->sale->id;
$this->getRefundPayment($transaction_id);
public function getRefundPayment($transaction_id){
$this->API_UserName = urlencode($this->API_Username);
$this->API_Password = urlencode($this->API_Password);
$this->API_Signature = urlencode($this->Signature);
$this->version = urlencode($this->version);
$transactionid = $transaction_id;
$DataInArray['currencyCode'] = 'INR';
$DataInArray['refundType'] = 'Full';
$DataInArray['transactionID'] = $transactionid;
$DataInArray['invoiceID'] = '';
$DataInArray['memo'] = 'This is refund of transaction id ='.$transactionid;
$DataInArray['amount'] = '';
if(trim(#$DataInArray['currencyCode'])=="")
return array("ERROR_MESSAGE"=>"Currency Code is Missing");
if(trim(#$DataInArray['refundType'])=="")
return array("ERROR_MESSAGE"=>"Refund Type is Missing");
if(trim(#$DataInArray['transactionID'])=="")
return array("ERROR_MESSAGE"=>"Transaction ID is Missing");
$Api_request = "&TRANSACTIONID={$DataInArray['transactionID']}&REFUNDTYPE={$DataInArray['refundType']}&CURRENCYCODE={$DataInArray['currencyCode']}";
if(trim(#$DataInArray['invoiceID'])!="")
$Api_request = "&INVOICEID={$DataInArray['invoiceID']}";
if(isset($DataInArray['memo']))
$Api_request .= "&NOTE={$DataInArray['memo']}";
if(strcasecmp($DataInArray['refundType'], 'Partial') == 0) {
if(!isset($DataInArray['amount'])) {
return array("ERROR_MESSAGE"=>"For Partial Refund - It is essential to mention Amount");
} else {
$Api_request = $Api_request."&AMT={$DataInArray['amount']}";
}
if(!isset($DataInArray['memo'])) {
return array("ERROR_MESSAGE"=>"For Partial Refund - It is essential to enter text for Memo");
}
}
