Question Auto SMS Alert using Progress & third party application

There are several options. The most straightforward one is using a WebService which you can call directly from the ABL. If you google a little bit you should be able to find a buch of them out there.

The corporation I work for has its own SMS gateway for which server-side APIs are provided. But that is a proprietary solution that was built a long time ago and runs on the mainframe.

Historically (2007/8) I've used Clickatell and a cURL command line command to POST parameters to the Web Service.

Going back even further (1999) I did investigate the possibility for to use a GSM modem which could send SMS message. The GSM modem was to be connected to the serial port on a UNIX server.

This would enable us to send an SMS message when the internet connection was unavailable.

Clickatell are cheap at less than $0.05 cent's per message and possibly the most recognised band in the SMS market the world over. Everything comes at a cost.

  1. How many massages do you expect to send?
  2. Were in the world do you want to send the messages to?

You can find a free SMS provider but they seam to be locked to a particular region or/and there is advertising.

From doing a quick Google it looks like that there isn't a FREE SMS gateway providers with Web API in Singapore. You can pre-buy a 1000 SMS messages for $75 SGD per year http://www.bulksms.com.sg/.

It all depends if what you want is a 'nice to have feature' or is it a beneficial tool for administrator and users?
 
The possible alternative is to use Social Networking Mobile Apps i.e. LINE, Whatsapp or Facebook Messenger to inject/post a message there web-services API to be able to publish your message. I have never done this myself but it should be possible in theory.

Woops. It was a nice idea in theory but it looks like Facebook has dropped the chat API .
 
Nothing specific that I know of. It just works. I don't get any SMS spam so either the carriers block it or the spammers have determined it is pointless.
 
In some regions there are SMS web services, but they may be limited to personal use or to a maximum number of messages per day. We have taken the GSM modem approach and it seems to work fine.
