Bulk Web SMS at its very best ...

Supertext provides a very robust, rugged, and reliable platform for sending bulk sms on the Web. We are constantly doing research in our software development laboratory to come up with ever more efficient algorithms and new exciting features.


For developers, we have a robust and easy to use RESTful HTTP Application Programming Interface (API). It can be used with any programming language.
Sending SMS
The API for sending sms is specified below:[username]&password=[password]&destination=[destination]&message=[message]&sender=[sender]

On successful send operation the following code will be returned;
SENT:[number of units consumed] e.g. SENT:2 (SENT in uppercase followed by a full colon, then by the number of sms units used).

The meaning of the url parameters and returned error codes are explained below.

Checking Credit Balance
To check sms credit balance, use the following api(only your username and password are required):[username]&password=[password]

Successful checking operation will return the following;
BALANCE:[sms units balance] e.g. BALANCE:702 (BALANCE in uppercase followed by a full colon, then by the sms credit balance, 702 in this case).

Url Parameters
Here are some notes on the api url parameters, note that you should not include the square brackets when using the api's.
username : Your account username
password : Your account password
destination : the recipient's phone number in the usual or international format. Only one number is permitted in the API, you will normally write a loop if you want to send sms to multiple numbers.
message : the text message you want to send.
sender : the sender ID to appear on recipient's phone. Maximum of 11 characters as usual, if more than 11 characters, the first 11 characters will be used.

Example :
