Receive SMS or Text Messages from SMS API/ SMS gateway developer API:
How it works? Step 1: User sends a text message to an assigned shortcode. Step 2: Message received by TxtImpact server from carrier. Step 3: TxtImpact parses the message, and redirect to clients’ server based on short code, and prefix assigned. Requirements: Client should set a web service to receive messages from TxtImpact servers. TxtImpact will send a message to client server in the following format. When configured you can pickup values from our GET request in following way using PHP PHP:
<?php
$sender = $_REQUEST['MobileNumber'];
$content = $_REQUEST ['Message'];
$inNumber = $_REQUEST ['shortcode']; 
$Rcvd = $_REQUEST ['Rcvd'];
?>
HTTP URL’s http://[client web service url]? MobileNumber=xxxxxxxx&Message=xxxxxxx&SMSINBOXID=388&shortcode=xxxx HTTP METHOD GET Parameters MobileNumber: User’s mobile number Message: Text Message sent by user Rcvd: Message received date & time SMSInboxid: Reference number for all incoming messages
