A webhook is an automated message sent from one application to another via HTTP.
It is defined as an authorized POST or GET request to a defined URL. For
example, a webhook can be used to send a notification to a Slack channel when a
new page is created in TYPO3.

TYPO3 supports incoming and outgoing webhooks:

*   The system extension :doc:`Reactions <ext_reactions:Index>` provides the
    functionality to receive webhooks in TYPO3 from third-party system.
*   The system extension :ref:`Webhooks <ext_core:feature-99629-1674550092>`
    provides the possibility to send webhooks from TYPO3 to third-party
    systems.
