Hi Jay
How can we Configure it for sandbox?

@vishaldu123

 $apiContext = new \PayPal\Rest\ApiContext(
         new \PayPal\Auth\OAuthTokenCredential(
         'xxxx', // ClientID
         'xxxx'      // ClientSecret
         )
 );
$apiContext->setConfig(
    array(
        'mode' => 'live'
    )
);

More on this here

Hi , thanks for this code,
I m new on paypal .. i try to implement the server rest solution on web site.
Question : the '\PayPal\Auth\OAuthTokenCredential(' on Sandbox context is for the seller .. ? [email protected] ?
Or the Buyer credential .. in this case your script is an 'Pay Button' emulation .. isn't it ?

Hi,
When I am using the api with live credentials it gives me error like "Access token does not have required scope". Is there any setting that I need to do in merchant account?
My code is below -
$apiContext = new \PayPal\Rest\ApiContext(new \PayPal\Auth\OAuthTokenCredential('client id', 'secreat key'));
$apiContext->setConfig(
array(
'mode' => 'live',
)
);

Please help
Thanks
