The Club Texting SMS Server allows SMS messages to be received using HTTP through the means of keywords on our short code 25827. This page details the format of the HTTP requests which are send by the Club Texting SMS Server to allow the receipt of SMS text messages by external software systems.

The Club Texting SMS Server will push received SMS messages by making an HTTP GET to the provided URL to indicate the receipt of an SMS message.  You can input this URL on the Keywords section of your Club Texting account.

Example URL:
http://www.yourdomain.com/receivesms.php

Message Format
On receipt of an SMS we will send an HTTP GET request to your server, using the parameters included in the table below:

Example Request Sent:
http://www.yourdomain.com/receivesms.php?PhoneNumber=5554443333&Message=Hello%20my%20friend

Response To The Server
When the GET post is made to your server, your script must output your sms response in plain text format (max 130 characters) that will be sent back to the originating phone number through our 25827 shared short code. This response must be given in a timely manner (sub 60 seconds) or it will be abandoned. No additional calls to our servers are necessary.

Security Considerations
To ensure the authenticity of the HTTP requests you should only accept requests from the following Club Texting IP addresses:

* 66.148.74.128/130

The HTTP endpoint can be an HTTPS (SSL) URL to protect the data whilst in transit.

Receiving SMS Responses From Your Inbox
You may have replies that go into your Inbox sent to your server via the Forwarding option located on the left navigation of your clubtexting.com. You may specify a URL to send your responses to.
