Installation¶
Follow the standard process of a TYPO3 installation (see TYPO3 Upgrade Guide). After TYPO3 is running, we can continue installing the headless extension:
- Install and activate the extension with Composer - composer require friendsoftypo3/headless(recommend), or using the extension manager with key- headless.
- Create a new root page: The page will provide our JSON API endpoint.   
- Create a new root template: Add headless to "Include static (from extensions)". After saving and displaying the page, we can see already the JSON output. 
- Create a site configuration: The site URL is needed as endpoint URL for the frontend. In TYPO3 v10 an autogenerated site configuration might exsist which we can rename and configure to our preferences. - Important - We recommend to use an URL like - https://api.mydomain.orgas endpoint, because it might come to unexpected behaviours with URLs like- https://mydomain.org/api. Probably this will be improved in a future version.
