NatureWhistle.Notifier.Webhook (nature_whistle v0.2.0)

Generic HTTP webhook notifier. Sends alerts to any endpoint.

Configuration

In your config/config.exs:

config :nature_whistle, notifiers: [
  webhook: [
    url: "https://your.service/hook",
    method: :post,                # default :post
    headers: [{"x-api-key", "abc"}],
    body_template: :simple        # or :full, or a custom function
  ]
]

Options

• :url – required, the HTTP endpoint.
• :method – optional, default :post. Can be :put, :delete, etc.
• :headers – optional, list of {header, value} tuples.
• :body_template – optional, controls the JSON payload:
  • :simple – sends %{text: message} (default).
  • :full – sends %{text: message, metadata: metadata, timestamp: ...}.
  • a function of arity 2 – receives (message, metadata) and returns a map.

This notifier automatically retries failed requests (3 attempts by default) with exponential backoff. Retry settings can be adjusted under the :retry key in the :nature_whistle configuration.
