name: Webhook Relay
version: 1.0.1
description: "Reads the alerts that vendors pushed to riposte-relay, the public mailbox for alert webhooks (riposte/relay/). Riposte accepts no inbound connection, so a source whose only output is a webhook — Rapid7 InsightIDR Essential basic detection rules, for one — posts to the relay, and an alert rule on this integration reads one relay source back over outbound HTTPS. The relay knows no vendor: the rule chooses the client, the alert type and the mapper. A read consumes nothing; the rule's watermark is the read's `since`, so after a failover the standby reads the same mailbox from its own watermark."
changelog: "1.0.1 — The generic mapper fills the OCSF fields that have a place for a relayed message: metadata.logged_time (receipt), metadata.log_provider and log_name (relay, source), metadata.labels (the checks passed, relay:hmac…), raw_data (the payload). The sender address goes to unmapped.relay.sender_ip, not src_endpoint.ip: it is the vendor's cloud, and as an entity it would tie every alert of that vendor together. metadata.product.name no longer holds the source id. | 1.0.0 — Initial release: fetch_messages (ingestion: one alert per relayed message, `since` watermark, page walk), relay_status, test_connection, and a generic mapper that keeps the raw body and the checks the message passed."
