You will find the TYPO3 Supertext Localizer here. It works the same way like the general Localization Manager for TYPO3 but with the added benefit that you get to connect directly to the Supertext API. Hence your orders end up directly with Supertext.

Go to the desired page and add the URL to the settings.
URL for the Supertext testing environment: https://staging.supertext.ch/api
URL for the Supertext live environment: https://www.supertext.ch/api
