Receiving SMS Messages with Short Code Keywords

A short code keyword is a unique one-word phrase that identifies a business, product or service. Keywords allow multiple  businesses to run unique campaigns on the same short code. Likewise, a business using a dedicated short code can differentiate communications with multiple keywords. For example, your dentist places a sign in the waiting room that says, “Text SMILE to 55512 to get appointment reminders.” In this example, “SMILE” is the keyword, and “55512” is the short code. By texting SMILE to short code 55512, the patient is opting in to receive appointment reminders. Using the same short code, the dental office may run a separate promotional offer. For example, “Text WHITE to 55512 for $25 off teeth whitening.” In this way, patients choose the interaction they wish to receive from their dentist. Communication with short codes and keywords give businesses great flexibility and responsiveness when engaging their customers, patients, or clients with text messaging. Here are guidelines and rules to consider when using keywords:

Select User Friendly Keywords

Keep it short – A short keyword is easy to remember.

Make it memorable – An easy to remember keyword will generate a better response.

Use a single word – SMS Notify! will match the entire message when checking for incoming keywords. If an incoming keyword is followed by any characters, a match will not be made.

SMS Notify! Incoming Keyword Rules

  • Only 1 instance of keyword per short code
  • Keyword cannot be a system keyword (e.g., STOP, HELP, ect.)
  • Keyword must be at least 3 characters long
  • Keyword cannot be a typical SMS response (e.g., sure, yes, thanks, monday)
  • Keywords are not case sensitive; ‘THIS’ is the same as ‘this’ and ‘ThIs’

Using PostBackURL to Capture Incoming Keywords

Developer’s can set up automated responses to incoming keywords using the SMS Notify! API PostBackURL system. When a keyword is assigned to your short code, CDYNE can also assign a URL or webpage you designate. Set your application to look for the variable SMSResponse=1, which is posted when a message is sent to your short code, or when a response to your outgoing message arrives. PostBackURL data is posted behind the scenes, and is not visible on your webpage. Program your application to capture the PostBackURL variables that are passed to your webpage from SMS Notify! API.
