Hi,
Trying to execute a payment using PHP-SDK, all the process goes well until the execution.
$payment = \PayPal\Api\Payment::get($paymentId, $this->apiContext);
$execution = new \PayPal\Api\PaymentExecution();
$execution->setPayerId($payerID);
try {
$result = $payment->execute($execution, $this->apiContext);
try {
$payment = PayPal\Api\Payment::get($paymentId, $this->apiContext);
} catch (Exception $ex) {
exit(1);
}
} catch (Exception $ex) {
exit(1);
}Running the execution function failed every time with the same "Client Authentication failed" error.
Why the authentication failed only for the execution? what i'mdoing wrong?
