SMS Notify! API System Keywords

SMS Notify! API is a programming interface that provides connectivity to wireless carriers. It allows developers to build business applications to send and receive text messages using DIDs or short codes. DIDs are SMS-enabled 10-digit phone numbers (e.g., 757-544-9510), and short codes are 5- to 6-digit numbers (e.g. 55512). Here is a PDF document outlining the differences between each method. One important feature of SMS Notify! is the system keywords. When a person begins a text message with a system keyword and sends it to your DID or short code, SMS Notify! will automatically send a text message reply. System keywords and responses vary between DIDs and short codes as outlined below.
