 You can access the PHP API by injecting relevant services into your code:
 
 - By using [auto-wiring]([[= symfony_doc =]]/service_container/autowiring.html), and the service classname in the `Ibexa\Contracts` namespace (see `bin/console debug:autowiring | grep Ibexa.Contracts`).
 - By using [service parameters]([[= symfony_doc =]]/service_container.html#service-parameters), and service aliases (see `bin/console debug:autowiring | grep ibexa.api`).
-- By using the repository's `get[ServiceName]()` methods, for example, [`Repository::getContentService()`](php_api_reference/classes/Ibexa-Contracts-Core-Repository-Repository.html#method_getContentService), or [`getUserService()`](php_api_reference/classes/Ibexa-Contracts-Core-Repository-Repository.html#method_getUserService).

     It supports auto-wiring.
 
 This isn't required in template functions or controller code, as the HTTP layer takes care of identifying the user, and automatically sets it in the repository.
