Curl error: unable to set private key file: 'C:.....privateKey.pem' type PEM

[fordiego44]

Hi I am from Peru.

I have this error When I run the api "funds_transfer_api" in my local with XAMPP, using its files in PHP :

---------------------------------------------------------

Curl error: unable to set private key file: 'C:\xampp7\htdocs\PROYECTOS_2020\diego_visadirect\visa_direct\funds_transfer_api\privateKey.pem' type PEM

---------------------------------------------------------

I follow the tutorial in his page and I generate the "privateKey.pem" and I get the "cert.pem", and in his manual in PHP  I set this certificates for use the API, but I get the error. 

I tryed use the function cURL how show the page of PHP, and I get the same error. This is the code :

<?php
    
    $tuCurl = curl_init();
    curl_setopt($tuCurl, CURLOPT_URL, "https://sandbox.api.visa.com/visadirect/fundstransfer/v1/pullfundstransactions/123");
    curl_setopt($tuCurl, CURLOPT_PORT , 443);
    curl_setopt($tuCurl, CURLOPT_VERBOSE, 0);
    curl_setopt($tuCurl, CURLOPT_HEADER, 0);
    curl_setopt($tuCurl, CURLOPT_SSLCERT, realpath("cert.pem"));
    curl_setopt($tuCurl, CURLOPT_SSLKEY, realpath("privateKey.pem"));
    curl_setopt($tuCurl, CURLOPT_POST, 0);
    curl_setopt($tuCurl, CURLOPT_SSL_VERIFYPEER, 1);
    curl_setopt($tuCurl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($tuCurl, CURLOPT_HTTPHEADER, array("Content-Type:  application/json,application/octet-stream"));

    $tuData = curl_exec($tuCurl);
    if(!curl_errno($tuCurl)){
      $info = curl_getinfo($tuCurl);
      echo 'Took ' . $info['total_time'] . ' seconds to send a request to ' . $info['url'];
    } else {
      echo 'Curl error: ' . curl_error($tuCurl);
    }

    curl_close($tuCurl);
    echo $tuData;
?>

I fixed my problem, when a create my own private.key to create my cert.pem don´t work but When I generate automatically with the page of visa (the private key) its work. and Also work when i do method GET . 

When I do POST. I copy the sample parameters that show visa developer, but show an error 

-------------------------

string(141) "{"responseStatus":{"code":"9501","severity":"ERROR","message":"Invalid input found, please correct the input data","info":"","status":"400"}}"

------------------------- 

I think that I should change the structure the sample parametres of visa: 

curl_setopt($tuCurl, CURLOPT_POSTFIELDS, json_encode("{
                    'acquirerCountryCode': '840',
                    'acquiringBin': '408999',
                    'amount': '124.02',
                    'businessApplicationId': 'AA',
                    'cardAcceptor': {
                    'address': {
                    'country': 'USA',
                    'county': '081',
                    'state': 'CA',
                    'zipCode': '94404'
                    },
                    'idCode': 'ABCD1234ABCD123',
                    'name': 'Visa Inc. USA-Foster City',
                    'terminalId': 'ABCD1234'
                    },
                    'foreignExchangeFeeTransaction': '11.99',
                    'localTransactionDateTime': '2020-07-15T02:46:25',
                    'retrievalReferenceNumber': '330000550000',
                    'senderCardExpiryDate': '2015-10',

                    'senderPrimaryAccountNumber': '4895142232120006',

                    }
                    }"));

Excellent!

There is no cost to you to use Visa Direct APIs in the sandbox. When you are ready to transition to production use of the Visa Direct APIs, there are fees for each of the APIs that are used. Fees are evaluated by application,  as they are a function of many elements, including the nature of your application and your relationship with any existing Visa partner(s).  We treat production applications on a case-by-case basis and work with you to determine appropriate pricing.  Please navigate to the below link for additional information on Visa Developer pricing.

Currently, only Visa accounts can receive push payments from Visa Direct. Please navigate to the below link for information on what account types can receive Visa Direct payments/transfers.
