# Corelayer Changelog: May 2026 Release

> May 2026 Corelayer release notes: the Custom Webhook integration, which accepts alerts from any monitoring tool through a single generic endpoint.

<Update label="May 17, 2026" tags={["New"]}>
  ## Custom Webhook integration

  You can now send alerts to Corelayer from any monitoring or alerting tool using a generic webhook endpoint. This unlocks sources that don't have a first-party integration yet — including Grafana, Alertmanager, and in-house monitors.

  Each webhook source gets a unique URL and bearer token, with a ready-to-copy `curl` command for verification. `trigger` alerts start a Corelayer investigation automatically, with fingerprint-based deduplication for repeated alerts.

  You can create multiple webhook sources from the same integration, reset tokens, and enable or disable individual sources without losing their configuration.
