Welcome to developers.hslmobile.com which contains documentation for the APIs from HSL mobile (including hslsms.com and smscarrier.com) that comprise our mobile communication services.  You should find all the technical information that you require on this site in order to make use of our APIs, but if there’s anything you’d like to see or any questions that you have then please contact us.

If you’re looking for documentation, including user guides, on our solutions (AlertBroadcast, EmailSMS or WebSMS) please see the Documentation section at hslsms.com.

If you’ve just got your new account or are looking to see what’s involved in getting moving on the technical side then the Getting Started section should be your first port of call.

An extremely reliable service is provided to customers using HSL Mobile‘s robust infrastructure. This spans multiple service sites to provide solutions and APIs for customers to access our SMS services. The architecture page has more information on our infrastructure.
