Destinations
Each rule lists one or more destinations under alert: (for example email, slack, pagerduty). Every destination page lists one bullet per YAML option (required and optional) with a short description; example fragments from the same ElastAlert 2 reference appear indented under the option they illustrate, followed by a full working example rule you can paste into the Logit.io editor. For exhaustive detail and cross-alerter behaviour (subjects, Jinja, etc.), use the Full Reference.
Custom HTTP webhooks: To POST JSON to your own URL, use post (Webhook (HTTP POST)) or post2 (Webhook (HTTP POST 2, Jinja)) when you need templated payload or headers.
Shared formatting: Subjects, bodies, Jinja templates, top counts, and OpenSearch Discover links are configured on the rule — see Subject & body and Context & links.
Each destination page lists what you must set first, then common options with short explanations of what the values do. Key names follow standard ElastAlert 2 rules so examples from books, blog posts, or internal playbooks often work on Logit.io once you plug in your own index pattern, URLs, and secrets.
