400{"name":"MALFORMED_REQUEST_ERROR","message":"Json request malformed - php

Question

This is my connection to the database plus $apiContext
// Bootstrap and Configure
define('DB_HOST', '*');
define('DB_USERNAME', '*');
define('DB_PASSWORD', '');
define('DB_NAME', '*');
//get connection
$mysqli = new mysqli(DB_HOST, DB_USERNAME, DB_PASSWORD, DB_NAME);
include __DIR__ . '/autoload.php';
error_reporting(E_ALL);
ini_set('display_errors', '1');
use PayPal\Rest\ApiContext;
use PayPal\Auth\OAuthTokenCredential;
// Replace these values by entering your own ClientId and Secret by visiting https://developer.paypal.com/webapps/developer/applications/myapps
$clientId = '*';
$clientSecret = '*';
$apiContext = new ApiContext(
new OAuthTokenCredential(
$clientId,
$clientSecret
)
);
$apiContext->setConfig(
array(
'mode' => 'sandbox',
'log.LogEnabled' == true,
'log.FileName' == 'PayPal.log',
'log.LogLevel' == 'DEBUG', // PLEASE USE `INFO` LEVEL FOR LOGGING IN LIVE ENVIRONMENTS
'cache.enabled' == true,
)
);
This is how am creating batch payouts and testing from the sandbox.
if(!$mysqli){
die("Connection failed: " . $mysqli->error);
}
$query = "SELECT * FROM payments WHERE Channel ='paypal' AND status='2' ORDER BY created_at desc LIMIT 500";
//execute query
$result = $mysqli->query($query);
// # Create Bulk Payout
use PayPal\Api\Payout;
use PayPal\Api\Currency;
use PayPal\Api\PayoutItem;
use PayPal\Api\PayoutSenderBatchHeader;
// Create a new instance of Payout object
$payouts = new \PayPal\Api\Payout();
$senderBatchHeader = new \PayPal\Api\PayoutSenderBatchHeader();
$senderBatchHeader->setSenderBatchId(uniqid())
->setEmailSubject("You Have a new Payment");
$payouts->setSenderBatchHeader($senderBatchHeader);
// #### Sender Item
$i = 0;
while($row = mysqli_fetch_assoc($result)){
$senderItem[$i] = new \PayPal\Api\PayoutItem();
$senderItem[$i]->setRecipientType('Email')
->setReceiver($row['them_email'])
->setAmount(new \PayPal\Api\Currency("{ \"value\":\"{$row['tasker_amount']}\", \"currency\":\"USD\" }"))
->setSenderItemId($row['created_at'])
->setNote($row['pay_type']);
$i++;
$payouts->addItem($senderItem);
};
var_dump($senderItem);
// ### Create Payout
try {
$payouts->create(null, $apiContext);
} catch (PayPal\Exception\PayPalConnectionException $ex) {
echo $ex->getCode(); // Prints the Error Code
echo $ex->getData(); // Prints the detailed error message
die($ex);
} catch (Exception $ex) {
die($ex);
}
This is the error code plus the exceptions

Help me figure out why am getting this error am new to the PayPal Payouts API.

Answer 1

You should not be forming your own JSON string and passing it.
Instead, create an object using stdClass and assign properties and values to it. Then, use json_encode to pass to PayPal.
For example (excerpt, untested):
// Create empty object
$payAmount = new stdClass;
// Assign object attributes
$payAmount->value = $row['tasker_amount'];
$payAmount->currency = "USD";
// Create currency object
$currency = new \PayPal\Api\Currency(
json_encode($payAmount)
);
$senderItem[$i]->setRecipientType('Email')
->setReceiver($row['email'])
->setAmount($currency)
->setSenderItemId($row['created_at'])
->setNote($row['pay_type']);
I believe the issue comes from when you're calling the addItem method. This may solve your problem (use this entire loop). This also uses the modifications above:
while($row = mysqli_fetch_assoc($result)) {
// Create empty object
$payAmount = new stdClass;
// Assign object attributes
$payAmount->value = $row['tasker_amount'];
$payAmount->currency = "USD";
// Create currency object
$currency = new \PayPal\Api\Currency(
json_encode($payAmount)
);
$senderItem = new \PayPal\Api\PayoutItem();
$senderItem->setRecipientType('Email')
->setReceiver($row['them_email'])
->setAmount($currency)
->setSenderItemId($row['created_at'])
->setNote($row['pay_type']);
$payouts->addItem($senderItem);
};
Notice that I dropped $i, as it's useless in this case. You are appending the item in each iteration, so counting the item doesn't matter.
One last edit I could throw in here... Instead of creating a stdClass and json_encodeing it, you could use the methods that the Currency class has in the Paypal SDK:
while($row = mysqli_fetch_assoc($result)) {
$amount = new \PayPal\Api\Currency();
$amount->setCurrency("USD");
$amount->setValue((float)$row['tasker_amount']); // float values only
$senderItem = new \PayPal\Api\PayoutItem();
$senderItem->setRecipientType('Email')
->setReceiver($row['them_email'])
->setAmount($amount)
->setSenderItemId($row['created_at'])
->setNote($row['pay_type']);
$payouts->addItem($senderItem);
};
