In the Apibot file tree there is a path called
/extensions. The individual extensions should be copied there, each extension in a subpath of its own. If the extension subpath contains a file named after it (letter case matters), with extension ".php", it will be automatically included on Apibot start.
The extensions subpaths are scanned in an alphabetic order, case-sensitive. If you want them to be included in a different order, create in the
/extensions path a file named
extensions.php. Include in it the extensions you need, in the order you like. If such a file exists, extensions subpaths will not be scanned, as this file is expected to include everything needed.
