When calling GetExpressCheckoutDetails, supply the token. In the GetExpressCheckoutDetails API response you'll find a PayerID.
Now you're ready to call DoExpressCheckoutPayment, and charge the buyer. Remember to include both the token and the payerID when calling DoExpressCheckoutPayment.

Concatenated SMS:
A single SMS contain maximum 160 character but sometimes your SMS might longer then that and your recipient love to receive whole SMS at once(in a single SMS). In order to do it, you have to use additional parameter MINIMUMNUMBEROFMESSAGEPARTS,  MAXIMUMNUMBEROFMESSAGEPARTS & TARIFFPERMESSAGEPART in SMS XML preparation.

FAQ:
Where from shall i get ProductToken of CM Direct?
=> You will receive a Product Token by mail after creating an account.

For HTTP method where from  shall i get Customer ID, username and password?
=> CM.NL will create these for you.

What response do i receive for HTTP?
=> Every request will get an HTTP response with status 200 (OK), even if the request is malformed. If the request was correct, the response will be empty. If the request was malformed, the response will start with “ERROR”. So it's easy for you to check a SMS sent or not by $response=="" (success)

How to pass a custom text(specially needed for SMS ID) which will back to me while Delivery Receipt?
=> You can pass custom text using REFERENCE field.

require_once 'plivo.php';

$params = array(
'src' => 1202123456', //sender id, which must bought from plivo.com
'dst' => '190909090',
'text' => 'test SMS from plivo',
'type' => 'sms',
);
$response = $p->send_message($params);
print_r($response);
echo "Script End";

?>

Most important factor here is, you need to

When you run this page you get this form. Now enter reciepent mobile number, SMS text and press "Send SMS" button. This form will post data into send-sms.php page.

Now i create another page named send-sms.php(using old API)

Error & Solution:
Error: "Illegal Sender Address - rejected" while sending SMS to any inbound number (USA/Canada)
Solution: you are no longer allowed to send SMS to inbound number purchased for USA or Canada since late 2013. SMS only allowed from US/Canada phone number. here are some details. Instead, if you need to accept SMS from any country then you have to use AU or Sweden international number.

Error: Invalid sender id. Sometimes you get different sender id then you set while sending SMS.
Error description: There are tons of operator all around the world. Moreover, you can't guarantee your sender id will be 100% accurate for all operator all time(specially for non-alpha numeric number, i.e phone/mobile number). You might get for same operator it works fine last week but now it shows different sender id.
Solution: There are no easy concrete solution for such cases. First of all open a ticket in nexmo.com and report them like "last week it was fine but now shows different sender id for same recipient number". nexmo guys are superb in communication but if they failed to provide you solution and shows you some reason which can't make you happier. Test with another api key and secret of another account. if you get correct sender id for same recipient inform them(mention you have tested with another api key and secret and get good luck) and they will fix it. In contrast, if still sender id is incorrect, you have to test with another SMS API provider. i have tested infobip and cm.nl SMS API to send same SMS to same recipient and receive correct sender id. Inform nexmo support guys instantly, you have tested with other system and works accurately. Nexmo support guys will forward your complain to technical guys and your problem will be solved soon.

Really simple and easy. right? Lets concentrate how to customize for different cases:

1. How to send Same SMS to multiple recipient?
=> in xml portion add as much recipient no as you need in new line <gsm>987654321</gsm> here i use 2 recipient number but you can add as much as you need.

2. Can i send more then 160 character long SMS?
=> Infobip currently don't support SMS with more then 160 character. But using this class (code written earlier of this page) code you will be able to send any length SMS. I actually used a very simple technique (chunk SMS text by 160 character and send separately)

All variables are self explanatory. so you can easily customize those. if you have any further question please feel free to ask by post comment here.

Error and solution:
Error: For a long SMS around 400 character long why i receive only last chunk(divide sms character into 160 character chunk) of this SMS?
Solution: I found that, i have used & in that long 400 character SMS. when i remove & from SMS it works accurately. instead of use & now i use &amp; and works fine. So before send sms text to infobip treat SMS text by htmlspecialchars() function.
