In addition to high levels of transmission security and availability, Retarus also attaches a great deal of importance to providing services which are highly flexible.\n<h3>Retarus Fax Services now with RESTful API<\/h3>\nThis flexibility is ensured particularly through offering a great range of different communication interfaces. While many fax service customers prefer the SOAP interface, especially in the <a href=\"https:\/\/www.retarus.com\/industries\/retarus-cloud-messaging-services-for-internet-economy\/\" target=\"_blank\" rel=\"noopener noreferrer\">Internet Economy<\/a> the trend has for some time been towards <a href=\"https:\/\/en.wikipedia.org\/wiki\/Representational_state_transfer\" target=\"_blank\" rel=\"noopener noreferrer\">REST<\/a>-based interfaces. Retarus has made a mission of always providing services on the basis of the latest standards and technologies. That\u2019s why Retarus is now making a RESTful cloud fax API available for all outbound fax services.\n<h3>The majority of online services are REST conformant<\/h3>\nThe main focus of the REST architecture (short for Representational State Transfer) is on machine-to-machine communication and web services. The advantage of REST consists of the fact that a large portion of the infrastructure required for REST is already on hand (e.g. web and application servers, HTTP-enabled clients, security mechanisms). As a result, many online services are already REST conformant per se.\n\nIn addition to the Soap and REST conformant interfaces already mentioned above, <a href=\"https:\/\/www.retarus.com\/fax-api\/\">Retarus\u2019 cloud fax services<\/a> also support connection via (s)FTP, HTTP\/S, MQSeries, VPN (IPSec) starting from RFC 2401 or SMTP.\n\nYou can <a href=\"https:\/\/www.retarus.com\/products\/fax-service-for-applications\/\" target=\"_blank\" rel=\"noopener noreferrer\">find out more here<\/a> about Retarus Faxolution for Applications or directly from <a href=\"https:\/\/www.retarus.com\/contact\/\" target=\"_blank\" rel=\"noopener noreferrer\">your local Retarus contact person<\/a>.\n","protected":false},"excerpt":{"rendered":"<p>While many fax service customers prefer the SOAP interface, especially in the Internet Economy the trend has for some time been towards REST-based interfaces.
