Configuration

This extension does not ship any extension-manager settings. Its services are registered through dependency injection in Configuration/Services.yaml.

Service registration

All classes under Classes/ are autowired and autoconfigured. The SiteRootService is additionally registered as a public singleton so it can be fetched directly from the container or via GeneralUtility::makeInstance():

services:
  _defaults:
    autowire: true
    autoconfigure: true
    public: false

  OliverKroener\Helpers\:
    resource: '../Classes/*'

  OliverKroener\Helpers\Service\SiteRootService:
    public: true
    autowire: true
    autoconfigure: true
    tags: ['singleton']

Microsoft Graph credentials

MSGraphMailApiService only converts a message into the Graph Message format — it does not authenticate against Microsoft Graph itself. Authentication and the actual sending are the responsibility of the calling code, which must provide a configured Microsoft Graph client (for example an OAuth2 client-credentials flow with tenant ID, client ID and client secret).
