This page requires that you are familiar with the Using the SOAP API page.
The sendmsg command allows you to send one or more SMS messages. To send messages to your database of mobile numbers, you can call this command in a loop.
The server will respond with a unique identifier for each message (referred to as an API message ID). This API message ID can be used to track and monitor the status of your message. If a message is rejected, an error will be returned.
In addition to authentication parameters, only to and text are required.
Many more parameters are available and listed in the send message parameters page.
For compatibility purposes, the callback parameter is named msg_callback (unlike our other API's). This is because callback is a built-in parameter in certain versions of Visual Studio.
