Caution
As of 2026-03-24, the Grafana OnCall OSS project is archived. The grafana/oncall repository is read-only, and active development continues in Grafana Cloud IRM. For a fully supported and actively maintained alternative, Grafana Cloud IRM offers a modern approach to incident response and on-call management.

Important: This documentation is about an older version. It's relevant only to the release noted, many of the features and functions have been updated or replaced. Please view the current version.

Outgoing webhooks HTTP API

Open source

Outgoing webhooks

⚠️ A note about actions: Before version v1.3.11 webhooks existed as actions within the API, the /actions endpoint remains available and is compatible with previous callers but under the hood it will interact with the new webhooks objects. It is recommended to use the /webhooks endpoint going forward which has more features.

For more details about specific fields of a webhook, refer to Outgoing webhooks.
