You can take a few steps to ensure that your integration with IoL will not break inadvertently.
New data properties might be added to existing data entity types in the future. Thus, the response for existing API methods might include new properties at any time. An integration need to be able to manage elements it does not recognize and ignore them. This usually isn’t a problem when using a standard REST/JSON library.
To future-proof your implementation, please ensure to build your application in such a way that you can handle new property fields in API responses. New fields may be added without notice.
