A guide to testing

Testing the Submit an application to change the land register APIs

HMLR provides a test environment for the Submit an application to change the land register APIs. We’ve also provided example code to demonstrate what you should expect when developing your own services.

You’ll find test stub examples on our API pages and example request and response code in the API technical guides.

Please note there are also plans to release a sandbox test environment for developers in the future. The exact release date is to be confirmed.

For additional support, contact our integration support team.

Testing SOAP and REST APIs

Information about testing SOAP and REST APIs will be added at a later date.


We sometimes use technical terms to describe the work we do at HMLR. For a list of commonly used terms and their definitions, visit our glossary.
