Java is platform independent, enabling you to develop and execute your program on any Java Runtime Environment (Windows, Linux, Solaris, etc.)

SMTP Gateway

It can also be used as an email to SMS feature. Simply send an email to the CellTrust Multimodal Gateway and we will convert it to an SMS or email and will send it to your list of recipients. You won't need to develop any code to connect your application or email address to the CellTrust Multimodal Gateway. It will also perform primary authentication and validation, generate an internal request, and forward the message to the CellTrust Multimodal Gateway for processing.

CellTrust SMS Gateway Scheduler API

External Applications can communicate with CellTrust's TxTScheduler API using an http request sent to containing the necessary information defined in TxTScheduler Request Parameters section. The TxTScheduler gateway will process the request and will schedule the message for delivery. If a redirect URL is provided in the parameters, the gateway will redirect the response to the destination pointed by redirect URL after completion of request processing, which is useful for directing the user to a new webpage within your website.

CellTrust SMS Gateway TxTFeedback API
