Multiple IP protection

September 14th, 2009

After a suggestion from a user of our gateway, a change has been made to the security module on our gateway, that limits connections by user to a particular IP.

The request was to allow multiple IPs per user, so that several computers can connect to the same account, allowing good security, without lacking usability.

The security module was successfully modified, and now allows several IPs to be authentic for a single user account.

If you would like extra IPs to be added to your accounts security module, send us an email to with the request.

If you have any suggestions for modifications to the API or ways which it could be improved or altered to suit your needs, submit a suggestion in our forum, and if it is feasable we will get to work on it straight away.

Undocumented gateway response codes

September 9th, 2009

Occasionally the gateway will respond with a response code that is not documented in our site’s Common API responses.

When this happens the response will be coming directly from the mobile network provider rather than generated from our own gateway, as such this is not something that can be documented.

However, these response codes almost always resolve to the phone number you are trying to send an SMS to, check you are using the correct number, and if it is international number, be sure to take a look at the article on International SMS numbers.

As always, if you have any questions please comment below, or register on our forum.

Non alphanumeric characters

August 27th, 2009

When a request to send an SMS is received by our gateway, it is processed by HTTP and some characters can commonly cause errors, which may lead to unpredictable results from your request.

To correct this issue, you should urlencode the message you want to send, so that the HTTP does not interfere with the message, this involves re-writing the message with characters such as & (ampersand) and # (hash) replaced with %23, %26 and so on. If your SMS program is written using PHP, there is a prebuilt function for performing this, which you can see here:

It is important however, that you initially change spaces to ‘+’ before url encoding the message.

As usual, if you have any questions regarding this technology, or anything related to the Hosting Ireland SMS Gateway API, either comment below, or in our forum or email

Credit Balance Request Command

May 19th, 2009

A request sent to the SMS API with correct Authentication details can now request its current balance, using the new Action property.

A sample request is displayed below:

The usual error messages, documented here apply, as well as a new XML response code, the response code is 101, which implies a succesful credit query, and will also have a log entry ID. an example reply is found below:

	<result code="101" id="cdaef13616e100fcd9fb80ef15a886ff">561</result>

This response code can now be used to check for sufficient credits before attempting to send a bulk of SMS messages, this will help prevent issues with your local sending code, and also reduce the load on the SMS API server.

As usual, you can send any feedback on this to or send a post in our forum.

Common API Responses

April 27th, 2009

Please find below a list of the most common API error responses, and possible reasons and corrections for them.

A response is defined as an error when the code is not 1, as result code 1 denotes an SMS succesfully delivered to the numbers network.

Message: Missing Required Fields Code: 501

Notes: This message means that the gateway did not receive enough information for an attempted delivery to be possible, this will occur when any of username, password, to and message are not supplied, if these are all sent, check that they are being sent as lowercase fields.

Message: Invalid Authentication Data Code: 502

Notes: This message means that either your submitted username was not found in the accounts, or the password supplied did not match the password for the username you sent. This would generally caused by invalid details, but these fields are case-sensitive, so check you sent them in the correct case.

Message: Insufficient Balance Code: 503

Notes: This message will only occur after you are succesfully logged into your account, and means that you do not have sufficient credits to send an SMS, this can only be corrected by topping up your credits balance.

Message: Invalid Recipient Code: 504

Notes: This error means that a problem was detected with the recipient number, most commonly caused by non-numeric characters in the to value.

Message: Error retrieving From Value Code: 511

Notes: This is an issue with the API, if this error is encountered an admin should be notified, along with the result ID.

There are other error messages that can be encountered, but it is unlikely that these will ever happen, if you do get an error that isn’t documented, and you are not sure what it means, please contact us, and we will help you understand the message.

SMS logs now available

April 21st, 2009

It has become neccessary to have logs available to users, so that messages sent through our SMS gateway can be investigated in the future.

With this in mind a new feature has been added to the the API, you can now request logs of your messages, using the URL:[&messageId=messageId]

If messageId is not presented, you will be given the logs for the last 100 (or all if the total is less than or equal to 100) connections from your account.

These logs are presented in XML 1.0 format, and you can see an example log below:

<?xml version="1.0"?>
	<log messageId="b7c10d6cbfe5496ec16acda8d0a187d0">
		<entry date="2009-04-21 13:15:27">logged in.</entry>
		<entry date="2009-04-21 13:15:27">999 SMS credits Left.</entry>
		<entry date="2009-04-21 13:15:27">to: 08fgh1414</entry>
		<entry date="2009-04-21 13:15:27">message: test</entry>
		<entry date="2009-04-21 13:15:27">from: 1890987000</entry>
		<entry date="2009-04-21 13:15:27">send result:  Invalid Destination Address</entry>

If the requested logfile is not in your account, or your login details are incorrect you will receive an error notifying you of the failure to receive a logList, you will also receive an error if you do not yet have any logs for any actions for your account.

Any comments on the logging system or the format of the XML should be entered through our forum, or in reply to this post.

SMS API XML responses

April 21st, 2009

For easier usage in automated implemenations the responses from the SMS gateway API will now be returned in XML 1.0.

An example response is below:

	<result code="503" id="8dbcbdf843c817eed5f8898066184412">

This allows the response to be collected by an XML object and used more dynamic usage than the original error text.

If you have any comments on the XML response codes implementation, please send any information to us, either in our forum or in response to this post.

IP protection

April 16th, 2009

We have finalised code that allows you to specify what IP address we should expect connections from, and will reject connections coming from any other addresses.

This has been tested succesfully, and is now implemented in the live API.
