# Event Sink The Event Sink channel allows you to forward EdgeTag events to any publicly accessible URL using standard POST requests. Once an event is fired in the browser and sent to the tag, the payload and its metadata will be sent as a JSON payload from the server. In order to authenticate the POST request to the endpoint, the channel can be configured to add additional request headers (e.g. `Authentication: Bearer XXXXX` or similar). ### Details Channel name: eventSink ### Event Flow All events sent through EdgeTag will be delivered using a POST request to the configured endpoint. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
