PayPal Rest API - End Point Used - paypal

Question

In my Dev environment, I can correctly use the Rest API to the sandbox site:
$sdkConfig = array(
"mode" => 'sandbox'
);
$cred = new OAuthTokenCredential(
$SANDBOX_clientId,
$SANDBOX_clientSecret
);
$access_token = $cred->getAccessToken($sdkConfig);
When using the same code with Live Keys and a verified Live account:
$sdkConfig = array(
"mode" => 'live'
);
$cred = new OAuthTokenCredential(
$LIVE_clientId,
$LIVE_clientSecret
);
$access_token = $cred->getAccessToken($sdkConfig);
I get this error:
Http response code 401 when accessing https://api.sandbox.paypal.com/v1/oauth2/token
How does the PayPal REST API know which endpoint to access?
I am not specifying the endpoint in the sandbox or live calls and am not using a bootstrap or ini file. The account is verified and approved.

The best way I would recommend is to create an ApiContext object similar to shown at https://gist.github.com/jaypatel512/a2b037ab5ddc51fa7280
<?php
// 1. Autoload the SDK Package. This will include all the files and classes to your autoloader
require __DIR__ . '/PayPal-PHP-SDK/autoload.php';
// 2. Provide your Secret Key. Replace the given one with your app clientId, and Secret
// https://developer.paypal.com/webapps/developer/applications/myapps
$apiContext = new \PayPal\Rest\ApiContext(
new \PayPal\Auth\OAuthTokenCredential(
'AYSq3RDGsmBLJE-otTkBtM-jBRd1TCQwFf9RGfwddNXWz0uFU9ztymylOhRS', // ClientID
'EGnHDxD_qRPdaLdZz8iCr8N7_MzF-YHPTkjs6NKYQvQSBngp4PTTVWkPZRbL' // ClientSecret
)
);
// Step 2.1 : Between Step 2 and Step 3
$apiContext->setConfig(
array(
'mode' => 'live',
'log.LogEnabled' => true,
'log.FileName' => 'PayPal.log',
'log.LogLevel' => 'FINE'
)
);
// 3. Lets try to save a credit card to Vault using Vault API mentioned here
// https://developer.paypal.com/webapps/developer/docs/api/#store-a-credit-card
$creditCard = new \PayPal\Api\CreditCard();
$creditCard->setType("visa")
->setNumber("4417119669820331")
->setExpireMonth("11")
->setExpireYear("2019")
->setCvv2("012")
->setFirstName("Joe")
->setLastName("Shopper");
// 4. Make a Create Call and Print the Card
try {
$creditCard->create($apiContext);
echo $creditCard;
}
catch (\PayPal\Exception\PayPalConnectionException $ex) {
echo $ex;
}
