Developer's REST SMS API v.2 - communicating with the SMS Gateway

This document provides a reference for all features available to you via the HTTP interface for sending SMS.
The HTTP API allows you to integrate your Application (Client) to smsGate (Gateway) using the HTTP protocol to send SMS.

General info

The Client issues a HTTP GET request to the smsGate HTTP interface supplying a list of required parameters. smsGate issues back a HTTP Response which indicates the success of the transaction.

Note that the delimiter used for status call in returned data, '|', is the pipe character (ASCII 124).

All parameters passed must be URL-encoded and also in UTF-8, as described in the following code samples.

API responses format

The API responds to all calls according to the parameter type. Accepted values for parameter type are: v2 which is the default value, json and xml.
Example of responses for API call key/get:

...&type=v2

Responds:

6fe2dd9c06df83

...&type=json

Responds:

{
   "status" : "1",
   "key" : "6fe2dd9c06df83",
   "remarks" : "Success"
}

...&type=xml

Responds:

<response>
   <status>1</status>
   <key>6fe2dd9c06ff83</key>
   <remarks>Success</remarks>
</response>

The commands available in this version of the smsGate API follows below.




API Key

The API Key should be used instead of username and password for all API calls. You can still use the username and password parameters, but we strongly recommend using the API Key instead for security reasons.

You acquire your API Key using the key/get call and you use it for all API calls instead of username and password parameters. If you need to change the API Key, you can do so using the key/reset call.
The key/get and key/reset calls are the only ones that require the use of username and password.
Once you get your API Key you can use it for all other API calls.
