Magento 2 Extension

The Magento 2 Extension can be installed using Packagist or alternatively installed manually by downloading from Github and adding to your server via FTP or by performing a manual extension installation.

We recommend using Composer and Packagist to install the Extension to ensure that all dependencies are installed along with the Extension.

  • To add the what3words Magento 2 Extension to a store using Packagist, first connect to your server and start the command line interface.
  • From the CLI run the command composer require what3words/module-what3words to install the files and dependencies required by the extension.
  • Next, run php bin/magento setup:upgrade to compile the site to ensure it includes the new extension
  • We then recommend running php bin/magento cache:clean and php bin/magento cache:flush to ensure the site’s cache is cleared.

Enable module

Select the store settings and a new category “what3words” will be available. Within the configuration page add the API Key.

A new field will then be available on the site’s checkout page.
