Webhooks

The workspace webhook is a plain HTTP POST — any receiver that accepts the payload works.

The workspace alert webhook is just an HTTP POST with a Slack-style JSON body. Any endpoint that accepts that shape works — a Slack incoming webhook, a relay, or your own service.

Payload

On a status change Uptimer POSTs:

{
  "attachments": [
    {
      "color": "#d50201",
      "title": "your rule name",
      "text": "…status message…",
      "footer": "Uptimer"
    }
  ]
}

Colours: recovered #2eb887 (green), down #d50201 (red), no-data grey.

This release has one Slack-compatible webhook per workspace — no per-rule routing, no custom templates or headers, no retries, and no other channels (email/SMS). If you need fan-out or a different format, point the webhook at a small relay you control.
