access allows messages to be sent from any software over the Internet. In this way, messages can be sent simply by calling up a URL.

This method is particularly suitable as a solution for web programmers (from PHP, .ASP…) . Simply put, it is functionally equivalent to calling up a web page.

WebService access

The WebService access offers the possibility to send messages to different call systems via standardised web methods.

SMPP access

This service provides access to the short message peer to peer (SMPP) interface to send SMS. The SMPP interface uses a standard protocol that is primarily used to connect to short message service centres (SMSC) for mobile phones. This direct connection allows, among other things, a large amount of messages to be sent very quickly, easily and reliably.

E-mail interface

This SMS API can be activated for free and makes it possible to send a transmission order directly by e-mail to a mobile phone (SMS), to a pager, to a fax (incl. file attachment), or to a telephone (voice message). Any e-mail program (MS Outlook, Gmail, etc.) can be used for this purpose.

REST access

Introducing our new REST API, perfect for sending SMS messages. While we plan to expand the functionality in the future, it is currently a reliable option for your messaging needs.
