SMSyeri offers simple SMS gateway connectivity for those who need to SMS-enable their systems, websites, or applications. Using SMSyeri's API (Application Programming Interface) integration is fast, simple and reliable.


Our API is immediately multicast messaging enabled, allowing integration to any front-end or legacy system, with a direct connection into SMSyeri's global gateways.

Learn more about each of our API connectivity options below:


HTTP/S API
Our most popular connection, HTTP is one of the simpler forms of communication to the SMSyeri API. It is used in the form of an HTTP/Internet Post. Register for HTTP/S


SMTP [E-mail to SMS] API
Another firm favourite, the SMTP API allows messages that are sent via e-mail to be converted to SMS. Popular with customers who already have an e-mail messaging system in place. Register for SMTP


SMPP API
Our most robust connection, suitable for customers who send large volumes of traffic. SMSyeri offers a global SMPP connection using the SMPP 3.3 standard. Customers are required to have SMPP client software in place, and unlike our other APIs there are minimum volume requirements when using SMPP. Register for SMPP


XML API
If you are familiar with XML, SMSyeri offers an XML interface with its own set of DTDs. Currently supports XML over HTTP. Register for XML


FTP API
Suitable for once off, high volume messaging. The FTP upload facility allows customers to upload text files to SMSyeri's FTP site, and have the files automatically dispatched to message recipients. Register for FTP


COM Object API
Popular with windows-based developers, the SMSyeri COM API object's rich set of methods and definitions make it easy for a user to integrate SMS sending into their programs or ASP pages. Register for COM Object

Utilising our API setup SMSyeri also offers Two-Way (bidirectional) messaging in over a 100 countries. Here you can find out more information on our Two-Way Messaging Services including information on our Premium Rate offering.

Please Note, new requirements in the US marketplace have enforced the use of US Shortcodes for all SMS traffic, sent or received. We therefore recommend dedicated Shortcodes for those who intend sending high volumes to the USA.
