Adaptive payments

When i try to send an adaptive payment, show this error.

Error message.
Client error: POST https://api-3t.sandbox.paypal.com/nvp/Pay resulted in a 404 Not Found response:

something about the actionType

When trying to do chained payment I always get this error:

ErrorId 520003
Message Authentication failed. API credentials are incorrect.

I double check my sandbox credentials and are correct:

    'username' => 'jorge.alexandro-facilitator_api1.gmail.com',
    'password' => '1364842417',
    'secret' => 'A8.lGiHnS.gATAUMTDDqJEv32m7eAEygtB5hcwPxiugnKJ6bio.Hl6xY',
    //'certificate' => '',
    'app_id' => 'APP-80W284485P519543T',

Same credentials works good in express checkout only adaptive is not working. Any idea or help?

please explain how to use this method

public function postNotify(Request $request)
{
$response = $this->parsePayPalIPN($request);

if ($response === 'VERIFIED') {                      
    // Your code goes here ...
}                            

}

I am working on a saas system where site partners add their paypal info and then get paid by their users directly. But the config file hardcodes this info, is it possible to override these variables from the controller ?

ErrorException in PayPalRequest.php line 291:
Object of class GuzzleHttp\Psr7\Request could not be converted to string

Can you help me? I use guzzle 6.0.1. When I do verifyIPN, I get this error.
Thanks.

Hi.

Using this package I can create recurring payments, right?

My question is, is it possible to change the amount to pay in the future? (notifying the user)

Thank you in advance.

Attempting to do ExpressCheckout. I am following the sample array $data
But I get this error from guzzle (v 6) "error" ["message"]=> string(47) "No method can handle the form_params config key"

I have not connected to my cart yet. Using Laravel 5.1

This line:
https://github.com/srmklive/laravel-paypal/blob/master/src/Services/ExpressCheckout.php#L35

is missing here:
https://github.com/srmklive/laravel-paypal/blob/master/src/Services/ExpressCheckout.php#L107-L118

{
type: "error",
message: "cURL error 35: Unsupported SSL protocol version (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)"
}

Hello!

I tried to execute the sample process in the readme but this is what I got:

array:9 [▼ "TIMESTAMP" => "2016-11-10T07:09:09Z" "CORRELATIONID" => "a4fc0e9a1e21" "ACK" => "Failure" "VERSION" => "123" "BUILD" => "26899334" "L_ERRORCODE0" => "10002" "L_SHORTMESSAGE0" => "Security error" "L_LONGMESSAGE0" => "Security header is not valid" "L_SEVERITYCODE0" => "Error" ]

I have followed the guide from https://developer.paypal.com/docs/classic/api/apiCredentials/ have the
API USERNAME (from Manage API Certificate page classic)
API PASSWORD (from Manage API Certificate page classic)
API SECRET (from sandbox, i created an app and it gave me secret key)
API CREDENTIAL (from Manage Api Certificate page classic, put in storage_path('app/cert_key_pem.txt')

Is there anything I'm missing here?

Thanks!

refundTransaction() in PayPalRequestTrait.php is private, so it's not possible to call it from the ExpressCheckout class.

here is my code

how can i get my sandbox username , password,secret ,appid, certicate
for express checkout for config file

return [
    'mode' => 'sandbox', // Can only be 'sandbox' Or 'live'. If empty or invalid, 'live' will be used.
    'sandbox' => [
        'username' => 'solyooo398523_api1.gmail.com',
        'password' => 'LPEP4ZJNMW3UY746',
        'secret' => '',
        'certificate' => '',
        'app_id' => '',    // Used for testing Adaptive Payments API in sandbox mode
    ],
    'live' => [
        'username' => '',
        'password' => '',
        'secret' => '',
        'certificate' => '',
        'app_id' => '',         // Used for Adaptive Payments API 
    ],

'payment_action' => 'Sale', // Can Only Be 'Sale', 'Authorization', 'Order'
'currency' => 'USD',
'notify_url' => 'http://localhost:8000/home', // Change this accordingly for your application.

];

I am so sorry. I am brand new to laravel and PayPal and I can't find any place inside your code to put my Client ID & Secret so still confused. if you made a video to explain how to use this package i will be
so happy

there is a reason why LOCALECODE is missed in setExpressCheckout call ?
(to force gateway language)

So i have a local setup, with ngrok (ngrok exposes your local site to the internet). I have also updated the ipn url in paypal's website.

The issue is that i dont get any notification back from paypal after the payment is complete. But when i try using the ipn simulator it responds back with proper post request. Now when the post request is passed through the "verifyIPN" method, it just gives an empty array shown below.

Array
(
    [INVALID] => 
)

So i have 2 questions,

1. does ipn work with Sandbox?
2. why does the verifyIpn takes in a proper POST request from the simulator and destroys it? Is it a bug?

Thanks again for this great library, i am really loving it :)

i'm constantly getting the following from my local

error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure

* The doc was also missing a few new changes and some clarifications, so i sent a pull request*

1. A new 'qty' attribute has been added, so the new format should be

 $data['items'] = [
            [
                'name' => 'Product 1',
                'price' => 9.99,
                'qty' => 1
            ],
            [
                'name' => 'Product 2',
                'price' => 4.99,
                'qty' => 1
            ]
        ];

2. Also in the docs it should be clear that secret refereces the signature.

Use of undefined constant CURL_SSLVERSION_TLSv1_2 - assumed 'CURL_SSLVERSION_TLSv1_2'

Hi,

I want to implement recurring payments with a trial period. Do you have an example of a complete flow for this?

currently when the user approves I do the following steps. but this doesn't create anything according to my test buyer account.

$response = PayPal::getProvider()->createBillingAgreement($request->token);

        $data = [
            'PROFILESTARTDATE' => \Carbon\Carbon::now()->addDays(14),
            'DESC' => 'Plan',
            'BILLINGPERIOD' => 'Month', // Can be 'Day', 'Week', 'SemiMonth', 'Month', 'Year'
            'BILLINGFREQUENCY' => 12, // set 12 for monthly, 52 for yearly
            'AMT' => 15, // Billing amount for each billing cycle
            'CURRENCYCODE' => 'USD', // Currency code 
            'TRIALBILLINGPERIOD' => 'Day',  // (Optional) Can be 'Day', 'Week', 'SemiMonth', 'Month', 'Year'
            'TRIALBILLINGFREQUENCY' => 14, // (Optional) set 12 for monthly, 52 for yearly 
            'TRIALTOTALBILLINGCYCLES' => 1, // (Optional) Change it accordingly
            'TRIALAMT' => 0, // (Optional) Change it accordingly
        ];
        $response = PayPal::getProvider()->createRecurringPaymentsProfile($data, $request->token);
        //$response = PayPal::getProvider()->doExpressCheckoutPayment($data, $request->token, $request->PayerID);
        dd($response);

thanks!

Hi!
When I try to get the data to the config file, I can only get these credentials from PayPal (sandbox and live):
Sandbox account (email)
Client ID
Secret

But the config wants these credentials:
username, password, secret, certificate,app_id
Any ideas?

Hello,

even after fixing some SSL issues #20 I am still getting 'Authentication failed.' message.

'response' => array('responseEnvelope' => array('timestamp' => '2016-07-12T00:57:21.056-07:00', 'ack' => 'Failure', 'correlationId' => 'ff9b97cb3df5d', 'build' => '23046607'), 'error' => array(array('errorId' => '520003', 'domain' => 'PLATFORM', 'subdomain' => 'Application', 'severity' => 'Error', 'category' => 'Application', 'message' => 'Authentication failed. API credentials are incorrect.')

I am not sure why I am getting this error, I found older issue #15 but that did not helped me...

Any ideas where should be problem? I checked credentials and everything should be correct.

I will try to debug it even more...

use case : Multiple user set there clientid & secret to get payment in there own account, is is possible to set the configuration dynamically.

config.php require some things isn't familiar with me like
'username' => '',
'password' => '',
'secret' => '',
'certificate' => '',
but my paypal app gave me Client id and secret

still confused

Hi srmklive, first of all, thanks for the great package, Im sorry to bother you but Im having real problems with the config/paypal file

For sandbox should we go to developer-> App api or paypal-> profile Certificates?
if its certificate, where can I get the secret? ( I just see the username,pass, and certificate)...
if its app I just see username(Sandbox account), secret and client_id (I don't know witch one is this), but no password or certificate...

Same goes for live (if its credentials, are they the same as live)?

Please help us, Im sure Im not the only one, appreciate the help
regards
Michael

I followed the guide exactly and finally got everything working. But i have some confusions on the ipn implementation. Right now i am just testing the library, so i dont have any tables for orders, carts or any other table neither do i have any data in my sessions.

So i am following this order:
setExpressCheckout
getExpressCheckoutDetails
doExpressCheckoutPayment
createRecurringPaymentsProfile

Then on the notify url i am getting a verified status.
My question is how does the ipn check whether the payment is exactly what was supposed to go through?

Hi,

I cloned demo app from another srmklive/laravel-paypal-demo. Following the steps, everything worked fine and I can see orders being placed perfectly, DB being updated as well. I was even able to manage the running state with my own Paypal sandbox details.

However, when I tried to add options using following:

$options = [ 'BRANDNAME' => 'MyApp', 'LOGOIMG' => 'https://upload.wikimedia.org/wikipedia/commons/c/c3/Eye.png', 'CHANNELTYPE' => 'Merchant' ];

Then I changed
$response = express_checkout()->setExpressCheckout($cart); to
$response = express_checkout()->addOptions($options)->setExpressCheckout($cart);

But it started throwing error that setExpressCheckout is being called on a null object. I tried changing helper function to Facade method, but no luck. I even tried breaking it in 2 parts:

$provider = Paypal:: setProvider('express_checkout'); $provider->addOptions($options); $provider->setExpressCheckout($cart);

But it gives same error. However I remove call to addOptions method, it works fine. I tried to debug $provider after addOption and getting null instead of an object. Earlier, when I wasn't using this demo and was trying my own following the documentation, I didn't face this problem (though with that IPN was failing).

Login PayPal account, and u will see the transationID of a payment.
Ex: Payment Received (Unique Transaction ID #0SP037792C904160H)
How can i get this ID,??
And in function setPaymentOptions, I want to add a Description of ReceiverOptions fields, u can help me add this parameter in your package.

Hello,
Am using this package for paypal IPN and its giving the following error
"ErrorException file_get_contents(): Filename cannot be empty. PayPalRequest:95"
Line 95 is this
$this->config['signature'] = file_get_contents($this->config['certificate']);

For IPN we don't need any credential or certificate file to respond with, so i have not provided any in the paypal config file, thus this error must be coming.

So there should also be a check for IPN, as did in line 264, and don't check and include credentials or certificate file when making request for IPN verification
if ($method == 'verifyipn') {

I have this createSubscrption method, which first uses setExpresscheckout to get the token (as defined in the docs). Then it passes this token to createRecurringProfile to create a profile.

public function createSubscription(){
        $data['items'] = [   [
                'name' => 'ISO 27000 Foundation',
                'price' => 0.99,
                'qty' => 1
            ] ];
        $response = $this->setExpressCheckout($data);

        if( isset($response['TOKEN']) ){
            $data['subscription_desc'] = 'My new Subscription';
            $result = $this->CreateRecurringProfile($response['TOKEN'], $data);
            dd($result);
        }
    }

The first method i.e setExpressCheckout works fine and generates a token, but the next method gives an error

/********** Result from setExpressCheckout **************/
array:7 [▼
  "TOKEN" => "EC-8X3617038X889902Y"

  "paypal_link" => "https://www.sandbox.paypal.com/webscr?cmd=_express-checkout&token=EC-8X3617038X889902Y"
]

  "L_SHORTMESSAGE0" => "Invalid Token"

Is this the correct way to creating a profile?

Are you looking to support 5.2 soon?

I noticed there was an issue when doing a vendor:publish

I updated the reference to the files in PayPalServiceProvider.php from

/../config/config.php to /../../config/config.php

After that I received an error

PHP Catchable fatal error: Argument 2 passed to Illuminate\Routing\UrlGenerator::__construct() must be an instance of Illuminate\Http\Request, null given

I commented out notify_url in the paypal.php file and then got this error

PHP Fatal error: Class 'Srmklive\PayPal\PayPalServiceProvider' not found

Ok, I dont know what I can be doing incorrectly here but I keep getting this error:

ErrorException in ExpressCheckout.php line 118:
Illegal string offset 'name'

When performing the doExpressCheckoutPayment($data,$token,$payerID);
Here is some sample code from my controller:

$response = \PayPal::getProvider()->getExpressCheckoutDetails($request->token);
$package = Package::whereName(array_get($response,'L_NAME0'))->first();
if($package)
{
  $data['items'] = [
    'name' => $package->name,
    'price' => $package->price,
    'qty' => 1
  ];
  $data['invoice_id'] = array_get($response,'INVNUM');
  $data['invoice_description'] = array_get($response,'PAYMENTREQUEST_0_DESC');
  $data['return_url'] = url('/return');
  $data['notify_url'] = url('/notify');
  $data['cancel_url'] = url('/cancel');

  $data['total'] = array_get($response,'L_PAYMENTREQUEST_0_AMT0');
  $provider = new ExpressCheckout;
  $doPayment = $provider->doExpressCheckoutPayment($data, $request->token, $request->PayerID);

ExpressCheckout.php:

    public function doExpressCheckoutPayment($data, $token, $payerid)
    {
        $num = 0;
        $post = [];

        foreach ($data['items'] as $item) {
            $tmp = [
                'L_PAYMENTREQUEST_0_NAME'.$num  => $item['name'], // This is my line 118
                'L_PAYMENTREQUEST_0_AMT'.$num   => $item['price'],
                'L_PAYMENTREQUEST_0_QTY'.$num   => $item['qty'],
            ];

            foreach ($tmp as $k => $v) {
                $post[$k] = $v;
            }

            $num++;
        }

        $tmp = [
            'TOKEN'                             => $token,
            'PAYERID'                           => $payerid,
            'PAYMENTREQUEST_0_ITEMAMT'          => $data['total'],
            'PAYMENTREQUEST_0_AMT'              => $data['total'],
            'PAYMENTREQUEST_0_PAYMENTACTION'    => !empty($this->config['payment_action']) ? $this->config['payment_action'] : 'Sale',
            'PAYMENTREQUEST_0_CURRENCYCODE'     => $this->currency,
            'PAYMENTREQUEST_0_DESC'             => $data['invoice_description'],
            'PAYMENTREQUEST_0_INVNUM'           => $data['invoice_id'],
            'PAYMENTREQUEST_0_NOTIFYURL'        => config('paypal.notify_url'),
        ];

        foreach ($tmp as $k => $v) {
            $post[$k] = $v;
        }

        $response = $this->doPayPalRequest('DoExpressCheckoutPayment', $post);

        return $response;
    }

Any help on this would be greatly appreciated. I know its probably something completely simple as well.

Hello,

I'm on Laravel 5.2. Tried to search on previous issues but had no clue. Did someone face this problem too? Thanks

Hello.
Tell me please!)
I created function:
public static function sendPayPallOrder($order){

$provider = express_checkout();

$data['items'] = [
    [
        'name' => 'Payment order',
        'price' => 100,
        'qty' => 1
    ],
];
$data['total'] = 100;

$data['invoice_id'] = $order->id;
$data['invoice_description'] = "Order #$data[invoice_id] Invoice";
$data['return_url'] = url('/payment/success');
$data['cancel_url'] = url('/cart');

$response = $provider->setExpressCheckout($data);

return $response['paypal_link'];

}
Also i created route:

Route::get('/payment/success', [ 'as' => 'order.payment-success', 'uses'=>'SiteController@paymentSuccess' ] );

And i created function:
public static function paymentSuccess(Request $request)
{
$data=[]; //???????????????
$input = $request->all();
$provider = express_checkout();
$response = $provider->doExpressCheckoutPayment($data, $input['token'], $input['PayerID']);
//dd($response);
}

How i can to receive $data in paymentSuccess function?

in your class ExpressCheckout.php your'e using array $tmp (119) to send options to paypal please add the possibility to modify this array.

I have one project to sale API SaaS.
Have you one demo?

Hello,

Awesome package, but i'm just wondering how to use IPN, or if it's complete.
When I log

$response = $this->verifyIPN($post);
Log::error($response);

The output is

array(
'INVALID' => '',
);

maybe if the response is valid, instead of throwing an empty exception it could be more informative as -

array(
'VALID' => true/false,
'ERROR_MSG' => '',
);

I got this response from PayPal
Client error: POST https://api-3t.sandbox.paypal.com/nvp/Pay resulted in a404 Not Found response:

My Controller:

public function adaptive()
    {
      $provider = new AdaptivePayments;

      $data = [
          'receivers'  => [
              [
                  'email' => '[email protected]',
                  'amount' => 9,
                  'primary' => true,
              ],
              [
                  'email' => '[email protected]',
                  'amount' => 1,
                  'primary' => false
              ]
          ],
          'payer' => 'EACHRECEIVER',
          'return_url' => url('payment/success'),
          'cancel_url' => url('payment/cancel'),
      ];

      $response = $provider->createPayRequest($data);
      //dd($response);
      $redirect_url = $provider->getRedirectUrl('approved', $response['payKey']);

      return redirect($redirect_url);

    }```

$redirect_url says payKey does not exist, but the cause is that $response throws a 404, it seems that https://api-3t.sandbox.paypal.com/nvp/Pay is unreachable

in PayPalRequest.php
doPayPalRequest()

if (!empty($response['TOKEN'])) {....
else{
// no connection
}

but it's also thrown "no connection" if other error happen. As in my case when total of items is different from the order total. I suppose it's for the translation.
I think better way of this will be to return the error returned by paypal. To know what really happened.

Currently I am using this library and I am able to make payment on sandbox environment.
On live user is trying to make payment via credit or debit card user is redirected to PayPal website, but payment is not completed.

Is this library supports for credit and debit card payment.?

I am getting below value in paypal_link:

"paypal_link" => "https://www.paypal.com/webscr?cmd=_express-checkout&token=EC-4RY600814B770294Y"

Also I checked with the paypal technical assistance they are saying "The API request stopped at SetExpressCheckOut" and from there it is not proceeding.

Kindly let me know is this correct for live or am I missing something.

The following code example will throw an error for... PayPal::getProvider() is null

$response = PayPal::getProvider()->doExpressCheckoutPayment($data, $token, $ppPayer);

When I revert to 1.1.7 the issue does not exist

I dont know if anyone havent notice it...
but
When We Subscriptions our Logic at setExpressCheckout is already Wrong...
We Dont Submit Items if we Have Subscriptions...
Also I Added Additional Info to Customize Checkout Page of Paypal
So What i did was check if data['items'] is set if yes go with normal workflow
if not dont do foreach loop of items...

I Also Added Here A Way to Customize Checkout Page in Paypal
Like Border and Logo and Branding Name...

public function setExpressCheckout($data, $subscription = false)
    {
        $num = 0;
        $post = [];

        if( isset( $data['items'] ) ) {
            foreach ($data['items'] as $item) {



            $tmp = [
                'L_PAYMENTREQUEST_0_NAME'.$num  => $item['name'],
                'L_PAYMENTREQUEST_0_AMT'.$num   => $item['price'],
                'L_PAYMENTREQUEST_0_QTY'.$num   => $item['qty'],
            ];

            foreach ($tmp as $k => $v) {
                $post[$k] = $v;
            }

            $num++;
        }

           $tmp['PAYMENTREQUEST_0_ITEMAMT'] = $data['total'];
        }

                ];

                foreach ($tmp as $k => $v) {
                    $post[$k] = $v;
                }

                $num++;
            }
            $tmp['PAYMENTREQUEST_0_ITEMAMT'] = $data['total'];
        }

        $tmp = [
            'TOKEN'                             => $token,

Does it means ssl certificate form here: http://bit.ly/292cxw7 or anything else ?

I got this error:

Use of undefined constant CURL_SSLVERSION_TLSv1_2 - assumed 'CURL_SSLVERSION_TLSv1_2'

So I made a search from closed issues and found out I need to update my OpenSSL version to 1.x. So did I:
root@vps# openssl version OpenSSL 1.0.2j 26 Sep 2016

Restarted the VPS, got the same error. So I thought I should also update my Curl:
`>>> curl_version();
=> [
"version_number" => 471808,
"age" => 3,
"features" => 1016733,
"ssl_version_number" => 0,
"version" => "7.51.0",
"host" => "x86_64-redhat-linux-gnu",
"ssl_version" => "OpenSSL/1.0.1e",
"libz_version" => "1.2.3",
"protocols" => [
"dict",
"file",
"ftp",
"ftps",
"gopher",
"http",
"https",
"imap",
"imaps",
"ldap",
"ldaps",

"pop3s",
"rtsp",
"scp",
"sftp",
"smb",
"smbs",
"smtp",
"smtps",
"telnet",
"tftp",
],
]

`

But im still having the same exact error.

I wanna see sample code in simple laravel app

I am getting this error

Use of undefined constant CURL_SSLVERSION_TLSv1_2 - assumed 'CURL_SSLVERSION_TLSv1_2

But i already have OpenSSL 1.0.1 installed which supports TLS 1.2, do you think this might be some other issue?

Hi buddy, i am looking for a solution to my app without a SSL certificate.
Can i only use this Express Checkout if i have an SSL certificate?
Thanks!

as i can see the paypal config is hard coded...
im planning to add a database for config...
with sandbox - boolean , username, password, secret, certificate , app_id and user_id
How can i Use Eloquent instead of the config file?
Is that possible thanks for the answer

just a dumb question, I'm new to paypal (used cashier/stripe before)

on https://developer.paypal.com/developer/applications/ i see three kind of app-interaction

v.zero SDK, REST API apps, NVP/SOAP API apps.

this package is intended to works with REST API?
I've generated a new rest api app and all I can see are this kind of credentials:

• Sandbox account (email)
• Client ID (hash)
• Secret (another hash)

this doesn't match the configuration of package
PAYPAL_LIVE_API_USERNAME
PAYPAL_LIVE_API_PASSWORD
PAYPAL_LIVE_API_SECRET
PAYPAL_LIVE_API_CERTIFICATE

So, can I have some reference link to paypal developer website?
thanks a lot for the package

I am trying to user express checkout. I am getting following error.

'response' => array('TIMESTAMP' => '2016-12-10T16:09:32Z', 'CORRELATIONID' => 'b1867d622585f', 'ACK' => 'Failure', 'VERSION' => '123', 'BUILD' => '000000', 'L_ERRORCODE0' => '10002', 'L_SHORTMESSAGE0' => 'Security error', 'L_LONGMESSAGE0' => 'Security header is not valid', 'L_SEVERITYCODE0' => 'Error')))

I think this is because I have not provided the certificate path in config/papal.php is it correct?
If yes then how I can create sandbox account certificate?
