In order to deliver a message, the system needs to authenticate the request as coming from a valid source. The following parameters are used to achieve this:

msisdn: This is the mobile number for your Corporate SMS account
password: This is the current password you have set for your account

You can have multiple threads open, however the session ID will expire after fifteen minutes of inactivity. You will then have to re-authenticate to receive a new session ID.

Example:

Command:
https://telenorcsms.com.pk:27677/corporate_sms2/api/auth.jsp?msisdn=xxxx&password=xxx

Success Response:
<?xml version="1.0" encoding="UTF-8" ?>
<corpsms>
<command>Auth_request</command>
<data>Session ID</data>
<response>OK</response>
</corpsms >

Error Response:
<?xml version="1.0" encoding="UTF-8" ?>
<corpsms>
<command>Auth_request</command>
<data>Error Code</data>
<response>ERROR</response>
</corpsms >

This Session ID must be used with all future commands to the API.
