New recall alerts in n8n and Zapier

Two ways: poll the new-recalls feed once an hour, or catch webhook messages. Either way, each recall has a stable id you can use to skip duplicates.

You need a free key (get one; it takes about a minute) in the environment variable RECALLDB_KEY. Keep the key on a server or your own machine, never in a web page.

The request both tools send

poll-new.sh
# What a no-code tool (n8n, Zapier, Make) sends every hour: new recalls since a time, newest first.
# On a free key the feed is a copy up to 1 hour old, so polling more often than hourly gains nothing.
curl "https://recalldb.app/v1/new?since=2026-11-15T00:00:00Z&category=vehicle&limit=20" \
  -H "Authorization: Bearer $RECALLDB_KEY"

Each poll counts as one request: hourly polling is about 720 a month, inside the free 1,000. On a free key the feed is a copy up to 1 hour old.

n8n

  1. Schedule Trigger: every hour.
  2. HTTP Request: GET https://recalldb.app/v1/new, query since = {{ $now.minus({ hours: 2 }).toISO() }} (a little overlap is safe) and any category or agency filter. Authentication: Generic, Header Auth, name Authorization, value Bearer rdb_your_key.
  3. Split Out: field data.
  4. Remove Duplicates: "Remove items processed in previous executions", compare field id.
  5. Slack or Send Email: {{ $json.title }}, {{ $json.issued_by }} and {{ $json.source.official_url }}. Add "Data from RecallDB" with a link.

Zapier

  1. Trigger: Webhooks by Zapier, event Retrieve Poll. URL https://recalldb.app/v1/new?limit=50, header Authorization = Bearer rdb_your_key, Key data, Deduplication Key id.
  2. Action: Slack, Gmail or any app. Map title, issued_by and source official_url, and add "Data from RecallDB".

Instead of polling: webhooks

Use Catch Hook (Zapier) or a Webhook node (n8n), register its URL with POST /v1/webhooks, and point a watchlist at it (see webhook alerts). Check the signature where the tool allows it (an n8n Code node can run the receiver's verify function).

Reference: GET /v1/new, integrations.
