+### OTP SMS API
+### Generate and send OTP
+
+```php
+<?
+
+//Your account username and password
+$username = "";
+$password = "";
+
+$client = new MobiWeb\Rest\Client($username, $password);
+
+//Generate OTP and send it via SMS to a mobile number
+$otp = $client->generate(
+  "44xxxxxxxxxx", //The mobile number in international E.164 format.
+  "SECUREPIN", //The sender that will be displayed in the OTP SMS. Can be composed of 2-11 alphanumeric characters (A-z,0-9, ,-,.) or 14 numeric characters (0-9). Special characters are not allowed.
+  "Please do not share your password pin. Your password pin is: [PIN]", //The text message of OTP SMS. Remember to put placeholder [PIN] in the message. If all characters in the message belong to the 3GPP GSM 7-bit GSM 03.38 ASCII character table, you can send up to 160 characters. If one or more characters in the message belong to the 16-bit Unicode / UCS-2 character table, because of the increased memory requirement for each character, you can send up to 70 characters. 
+  600, //The validity period of the pin in seconds. The default value is 600 seconds (10 minutes).
+  );
+
+//Print the generate OTP result. Remember to store the mobile number and the OTP id for later use.
+print_r($otp);

+?>

+
+### Validate OTP
+
+```php
+<?
+
+//Your account username and password
+$username = "";
+$password = "";
+
+$client = new MobiWeb\Rest\Client($username, $password);
+
+//Validate a previously generated OTP with the OTP ID. OTP is provided by the mobile number subscriber.
+$otp = $client->validate(
+  "564xxx", //The OTP ID returned by the generated OTP.
+  "44xxxxxxxxxx", //The mobile number of the subscriber in international E.164 format.
+  "265xxx", //The OTP provided by the mobile number subscriber. 
+);
+
+//Print the OTP validation attempt result. If result is TRUE, OTP is validated.
+echo $otp;

+?>
+```
+
+### Get account balance
+
+```php
+<?php
+
+//Your account username and password
+$username = "";
+$password = "";
+
+$client = new MobiWeb\Rest\Client($username, $password);
+
+//Get account balance and print it
+echo $client->getBalance();

+
+```php
+<?php
+
+//Your account username and password
+$username = "";
+$password = "";
+
+$client = new MobiWeb\Rest\Client($username, $password);
