Webhooks and reactions

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 Reactions provides the functionality to receive webhooks in TYPO3 from third-party system.
• The system extension Webhooks provides the possibility to send webhooks from TYPO3 to third-party systems.
