Send or receive text messages from your website or application with short codes. A short code is a special 5-6 digit number (e.g., 75195) that allows consumers to subscribe to mobile messaging campaigns. They are managed by a central issuing registrar in each country. Dedicated short codes can send up to 35 MT messages per second.


SimpleSMSSend Method

SimpleSMSSend is recommended for sending single, immediate text messages.

  • Your short code will be assigned to a unique license key. When this license key is passed using SimpleSMSSend, it will automatically send text messages from the assigned short code.
  • You can also assign a DID to the same license key to enable backup text messaging if the short code sends to an unsupported carrier. When this happens SMS Notify! will send the text message from the DID.

AdvancedSMSSend Method

AdvancedSMSSend is recommended for sending scheduled text messages and allows multiple numbers with one message, or multiple numbers with individual messages.

PostBackURL System

Know when your SMS was sent or received with the PostBackURL System. CDYNE SMS Notify! API will automatically post information to a URL you specify when text messages are sent or received via DIDs and short codes. PostBackURL data is posted behind the scenes, and is not visible on your webpage. Code samples are provided on how to capture this data to store in a database. CDYNE recommends that the data returned to be stored within your systems for reporting and reference information.

API Throughput

Dedicated short codes send up to 35 messages per second per short code.

Coverage & Area Codes

Short codes are country specific. A U.S. short code will only send messages in the U.S., and a Canadian short code will only send messages in Canada.

SMS and Daylight Savings Time

SMS Notify! recognizes the date and time in UTC (Coordinated Universal Time). When clocks move forward 1 hour in the spring, most time zones will need to remove one hour from their UTC offset. For example, Eastern Standard Time (EST) is UTC -5 hours but Eastern Daylight Time (EDT) is UTC -4 hours.
