The published service services for epostcode can be found at the URL below. (Current)

These services are also available securely via SSL (https) to enable seamless integration with secure web pages and applications. If you click on each of the links you will be taken a page where you will find everything you need to consume the web service as well as a list of the methods available.

There are a number of deprecated web services that are provided for legacy application support, but these should not be used for any new integration and will, at some point, be removed once all clients have migrated from them.

We are in the process of updating our documentation and code samples to support the new range of services and we will shortly be releasing and update which will include a full REST interface as well as providing backwards compatibility with the existing SOAP interface.  

You can get a formal definition or Web Service Description Language (WSDL) of the service by clicking on the Service Description link. (Current)

This WSDL is all that developers need to enable them to integrate the service into any website, intranet application or desktop application, such as a CRM or ERP system.

If you are interested in integrating have a look below where you will find code samples and downloads that should help you to get started.
