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.

REST access

Send reliable SMS messages via our flexible and modern REST API. Ideal for individual messages and mass mailings.

WhatsApp Business API

You can use the WhatsApp Business platform of our certified WhatsApp Business partner for your WhatsApp communication, e.g. for customer service and marketing. And completely GDPR-compliant. To do this, you link your WhatsApp account directly to the Business platform via the customer messaging software. As part of the configuration, an individual WhatsApp API key is created that connects your business account to the platform.

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.

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.
