Requirements
============

Meet every requirement on this page before installing the extension.

System requirements
===================

* TYPO3 13.4 LTS or 14.3
* PHP 8.3, 8.4, or 8.5
* TYPO3 Scheduler system extension
* PHP ``allow_url_fopen`` support for the Sentry reachability check

Sentry requirements
===================

* A Sentry project for the TYPO3 application
* An initialized Sentry PHP SDK with a valid DSN
* The organization slug and project represented by that DSN
* A Sentry user authentication token with ``alerts:read`` and ``alerts:write``
  permissions to manage issue alert rules and cron monitors
* Outbound HTTPS access from TYPO3 to the Sentry host

..  important::

    This extension depends on an initialized Sentry SDK but does not initialize
    it. Configure Sentry in the TYPO3 project before running Scheduler tasks.

Microsoft Teams requirements
============================

1. Add and configure the `Microsoft Teams integration in Sentry
   <https://develop.sentry.dev/integrations/msteams/>`__.
2. Add the Sentry app to the Microsoft Teams channel that should receive alerts.
3. Record the integration ID and exact channel name for the extension
   configuration.

    A successful Microsoft Teams integration first offers
    :guilabel:`Complete Setup` and then confirms that the Sentry installation
    succeeded.

..  important::

    The first channel in the Microsoft Teams team must be named ``General``.
    Channels created after it can use any name.

When these requirements are met, continue with the :ref:`installation`.
