SOAP / Webservices

OutboxSMS presents two SOAP interfaces, one for controlling OutboxSMS configuration, and the other for sending and receiving messages. Any programming or scripting language that supports SOAP can be used to control OutboxSMS and send messages. E.g. Perl, PHP, .NET, Python etc.

Plain Text Email

Messages can be sent and received by sending plain text emails. Most scripting languages and programming languages allow email to be sent and received. This can be used to interface to OutboxSMS.

COM Object DLL

If the application is developed on a Microsoft Windows operating system, a COM DLL can be used to interface to OutboxSMS. The COM API allows full control of the OutboxSMS configuration, status and messaging.

Plain Text Files

OutboxSMS message routing and queueing uses plain text message files placed in queue folders. The message files have a standard format, which makes it easy to construct and manipulate messages from external programs.
