Notifications

Email alerts, a weekly digest, and Slack or Discord messages when your QR codes get scanned or your forms get responses.

Choose what QRdx tells you about in Settings → Notifications. Settings are per person and per workspace: your personal workspace and every team you belong to have their own switches, and in a team every member picks their own.

Channel	What you can get	Plan
Email	Weekly digest, scan milestones, form submissions, new codes, code changes	Pro and Business
Slack, Discord	Scan milestones, form submissions, new codes, code changes	Business
Webhooks, Zapier, Make	Every event, including each scan	Business

Team workspaces follow the plan of the team's owners. Everything is off until you turn it on.

Alerts

Scan milestones: a code's first scan (with when, where and on which device), then 10, 100, 500, 1,000, 5,000, 10,000 scans and beyond.
Form submissions: the answers from a form on one of your hosted pages, with a link to all responses.
New codes and code changes: who created a code, or changed its destination, title, design or domain. Most useful in teams.

To keep a busy form or a bulk import from flooding your inbox or channel, each target gets at most 30 alerts of one kind per hour; the rest are skipped (the weekly digest still counts them, and webhooks still receive every event).

Weekly digest

Every Monday (UTC) you get last week's numbers for the workspace: scans compared with the week before, unique visitors, your top 5 codes, the top countries, new codes and form responses. It's skipped when there were no scans for two weeks and no form responses.

Email

Alert emails go to your account's email address. Each one has an Unsubscribe link that turns off that kind of email without signing in (mail apps that support one-click unsubscribe show it too). Turn emails back on, or off, in notification settings at any time.

Team invitations and other account emails are not affected by these settings.

Slack and Discord

Create an incoming webhook:
- Slack: add the Incoming WebHooks app, or your own Slack app with incoming webhooks, to a channel and copy the URL (https://hooks.slack.com/services/...).
- Discord: channel settings → Integrations → Webhooks → New Webhook → Copy Webhook URL (https://discord.com/api/webhooks/...).
In Settings → Notifications, click + Slack or + Discord in the workspace, paste the URL and pick the events.
Use the send button to post a test message.

Only Slack and Discord webhook URLs are accepted. After saving, QRdx shows only the start of the URL, because anyone who has it can post to the channel. Messages never mention @everyone, @here or roles, whatever visitors type into a form.

Plans and downgrades

If a workspace's plan no longer includes a channel, its alerts stop, but your settings are kept and you can still turn them off or remove targets. Your QR codes keep working on every plan.

Self-hosting

Emails are sent through Resend: set RESEND_API_KEY and EMAIL_FROM (an address on a domain verified in Resend). Without them, emails are skipped and logged, and team invites fall back to copyable links.

The weekly digest runs from a scheduled job on Monday mornings (apps/docs/vercel.json on Vercel calls /api/cron/digest?shard=all, which sends every subscriber's digest in one run). With many subscribers you can instead call it hourly on Mondays without shard=all, so each run handles a twenty-fourth of them. Elsewhere, call it with the CRON_SECRET from your environment:

curl -H "Authorization: Bearer $CRON_SECRET" https://your-host/api/cron/digest

Unsubscribe links are signed with BETTER_AUTH_SECRET; changing it invalidates links in emails already sent.
