Migrating an application from API V2 to API V3

easy

The what3words API has been updated to V3 with the benefits of a simplified interface and new functionality.

AutoSuggest has been greatly simplified and now features powerful new country clipping. Error handling has been improved for v3, making it easier and more robust to use v3.

With the release of V3 of the what3words API, V2 of the API is now officially deprecated, though V2 and V3 will continue to run in parallel for some time.
