provider: Metaplane
providerId: metaplane
asyncapi_published: false
note: 'Metaplane has a real event surface — outbound incident-alert webhooks with optional HMAC request signing
  — but publishes NO AsyncAPI document and no event-payload schema. Searched docs.metaplane.dev/llms.txt (complete
  published index), /asyncapi.yaml on every host, and the GitHub org; nothing. Nothing is fabricated here: the catalog
  below records what the provider documents, which is the transport and the security model, not the payload shape.'
transport: HTTPS POST to a customer-supplied URL
configuration:
  ui: https://app.metaplane.dev/settings/alerts
  api: false
  note: Webhook destinations are created in the web app only. There is no webhook or subscription operation in the
    published REST API — the 23 operations cover connections, monitors and tags.
security:
  signing: optional HMAC request signatures
  secret: a secret key issued by Metaplane at destination creation; shown once and rotatable
  source: https://docs.metaplane.dev/docs/webhooks
  note: The signature header name and canonical string are not published in the docs, so a consumer cannot implement
    verification from the documentation alone.
verification:
  supported: true
  how: The destination actions menu offers 'Verify', which sends a sample incident to the endpoint.
routing:
  source: https://docs.metaplane.dev/docs/alert-routing
  note: Alerts are routed to destinations by rule; tags on tables and monitors are the primary routing dimension
    (https://docs.metaplane.dev/docs/tags).
events:
- name: incident
  description: An incident is raised when a monitor fails. Metaplane groups related failing monitors into a single
    incident rather than alerting per monitor.
  payload_schema_published: false
  source: https://docs.metaplane.dev/docs/incidents
availability:
  note: 'The pricing comparison table lists ''API, Webhooks'' as alert destinations on the Enterprise tier only;
    Free and Pro get Slack, Email, MS Teams (+PagerDuty on Pro). Source: https://www.metaplane.dev/pricing'
