NIMTA is a messaging gateway provided by OnlineCity. Gateway subscribers can send SMS, MMS, and email to recipients in almost any country. NIMTA supports both dialog-based services, which send a message to one specific recipient, and information services, which send the same message to multiple recipients. NIMTA's API enables customers to build message-based services on top of the gateway. The NIMTA API comes in both SOAP-based and RESTful versions. The OnlineCity website is provided solely in Danish, but API documentation is given in English.
