Feishu / Lark#

IncidentRelay can send alert notifications to a Feishu or Lark group through a custom bot webhook. Both open.feishu.cn and open.larksuite.com webhook URLs are supported.

Create the custom bot#

• Open the target Feishu or Lark group.
• Add a custom bot and copy its webhook URL.
• Optionally enable signature verification and copy the signing secret.
• Keep the webhook URL and signing secret private.

Configure IncidentRelay#

Create a notification channel with type Feishu / Lark and set:

Typical webhook hosts are:

Copyhttps://open.feishu.cn/open-apis/bot/v2/hook/...
https://open.larksuite.com/open-apis/bot/v2/hook/...

Attach the channel to a route, then use Test on the Channels page to verify delivery.

Message format#

The notifier sends the rendered IncidentRelay notification as a custom bot text message:

Copy{
  "msg_type": "text",
  "content": {
    "text": "..."
  }
}

When a signing secret is configured, IncidentRelay also adds the timestamp and sign fields required by Feishu/Lark. Delivery fails when the provider returns either an HTTP error or a non-zero application response code.

Current limitations#

The Feishu/Lark channel sends text notifications only. Interactive ACK/Resolve/Shelve buttons and updates to previously sent messages are not supported.

The webhook URL and signing secret are masked in API and UI responses. To keep an existing value while editing a channel, leave the masked value unchanged.
