Developer Interfaces & APIs
Outbound, inbound and two-way SMS

What are Developer Interfaces & APIs?

SMS Virtual Numbers

Instead of using our Web Interfaces (Web to SMS and Group SMS) you can interface with the World Text SMSC programmatically. This gives you the flexibility to manage and control your bulk text messages from your own application and existing infrastructure.

Standard defining API interfaces - HTTP REST, SMTP, SMTP Bulk and SMPP, all at no additional cost.

Bespoke solutions - We know trying to fit a third party solution around your existing infrastructure or service provider can be difficult and take time you can't afford. Our in-house developers regularly creating bespoke solutions, and mapping your existing application calls to comply with the World Text API. To discuss your needs please contact us.


The REST interface is very easy to use. You can test in a browser and use it via any programming language capable of HTTP or HTTPS. Also see HTTP v1 (deprecated).

HTTP Helper Libraries

In creating these libraries we have encapsulated the API calls such that you don't need to be concerned directly with URLs, resources, the API calls themselves, or processing the raw JSON responses.


For high volume users requiring the most robust method of streaming SMS to our gateway. Unlike other providers we do not charge for this connection, or impose minimum SMS requirements.


Perfect for everyone who uses email! We understand not wanting to have to implement new systems or software, utilising your existing email system this is the answer.


Send a single email with dynamic contents to multiple recipients, ideal for those bulk marketing campaigns or alerts. Again, using your existing email system.
