Summary

The quota-exhausted email and the dashboard banner said a user's webhooks were being rejected with 429, but not how many or on which endpoints. They now do.

  • Migration 00060 adds get_quota_rejections(user_id, limit). It sums quota_rejected from endpoint_daily_stats for the current period (UTC days from the period start) on the user's own endpoints, leaving out endpoints billed to a subscribed team. It returns the top endpoints plus a total and endpoint count computed before the limit. Service role only.
  • Email: buildQuotaExhaustedEmail takes an optional rejections and lists the total and the top 5 endpoint slugs, with "and N more endpoints" for the rest. Slugs are HTML-escaped. With no rejections, or if the lookup fails, the generic email is sent unchanged.
  • /api/usage and QuotaBanner: /api/usage returns quotaRejections while the quota is exhausted (empty otherwise). The banner renders "N webhooks rejected this period on slug (n), …".
  • Web version 0.40.4 and a changelog entry.

Behaviour to know about

  • The poller emails within ~10 minutes of the limit being reached, so many first emails go out before any webhook has been rejected and use the generic copy. The 7-day resend lock is unchanged, so those users do not get a follow-up with counts.
  • endpoint_daily_stats is per UTC day, so the first day of a period can include a few rejections from just before it began.
  • quotaRejections is not added to openapi.yaml or the SDK types, matching teamBilledEndpoints and emails, which are also dashboard-only.

Test plan

  • pnpm typecheck, ESLint and Prettier clean
  • Web unit suite passes (75 files), including new tests for the email builder, poller, getQuotaRejections and the banner's QuotaRejectionDetail
  • New integration suite supabase-quota-rejections.test.ts: ordering, limit vs totals, period cutoff, team-billed exclusion, email and usage output, anon access denied
  • Full web integration suite against the local dev database with the receiver running: 509 passed, 24 skipped, 1 failed. The failure is agent-sandbox "sandbox_full when the pool is full". It passes alone and the code is untouched by this PR, so it looks like parallel-run flakiness, not confirmed on main.
  • Apply migration 00060 to production through the usual process before deploy. The code needs the function, and without it the poller falls back to the generic email.

Summary by CodeRabbit

  • New Features
    • Quota alerts show the total number of rejected webhooks and rejection counts for affected endpoints when your quota is exhausted.
    • Quota-exhaustion emails include the same breakdown, with a summary of additional affected endpoints when the full list is not shown.
    • Endpoints billed to subscribed teams are excluded from these counts. Rejection details are omitted when there’s no rejection data to report.

… (web 0.40.4)

Adds get_quota_rejections() (migration 00060), which reads per-endpoint quota_rejected counts from endpoint_daily_stats for the current period, leaving out team-billed endpoints. The quota-exhausted email, /api/usage and the dashboard QuotaBanner now report the total and the most rejected endpoint slugs. A failed lookup falls back to the generic email.

📝 Walkthrough

The change adds quota-rejection aggregation for eligible endpoints and includes the resulting counts in usage responses, dashboard quota alerts, and quota-exhaustion emails. Rejection details appear only when valid data is available.

Changes: Quota Rejection Reporting

Layer / File(s) Summary
Rejection aggregation and usage data
supabase/migrations/00060_quota_rejections.sql, apps/web/lib/supabase/database.ts, apps/web/lib/supabase/quota-rejections.ts, apps/web/lib/supabase/quota-rejections.test.ts, apps/web/lib/supabase/usage.ts, apps/web/tests/integration/supabase-*
The service-role RPC aggregates positive quota rejections for eligible endpoints. The usage data path fetches and maps rejection details when quota is exhausted. Unit and integration tests cover aggregation, access, limits, and usage data.
Quota-exhaustion email details
apps/web/lib/quota-emails.ts, apps/web/lib/quota-emails.test.ts, apps/web/lib/email/quota-exhausted-email.ts, apps/web/lib/email/quota-exhausted-email.test.ts
The email sender retrieves rejection details for each claimed user. The email builder includes counts in text and HTML when valid data is available, escapes endpoint slugs in HTML, and retains generic copy when details are unavailable.
Usage response and dashboard alert
apps/web/components/dashboard/quota-banner.tsx, apps/web/components/dashboard/quota-banner.test.tsx, apps/web/lib/changelog.ts, apps/web/package.json
The dashboard reads rejection details from the usage response and displays totals, endpoint counts, and any additional endpoints. Release metadata updates the web version and describes the feature.

28-28: CodeQL "Incomplete multi-character sanitization" alert on replace(/<[^>]+>/g, "").

Lines 36-40 and 43-47 use the same pattern. A previous review already flagged this. The regex only strips tags to compare visible text in test assertions. It does not sanitize untrusted input, so the alert is a false positive. The alert is still open as a failing check.

To clear it, use a small test helper that avoids this regex. For example, assert on renderToStaticMarkup output with toContain on the fragments. Or dismiss the alert in code scanning with a note.

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Rejection details stay empty while the banner is open.

The effect fetches /api/usage once, when exhausted becomes true. The doc comment on QuotaRejectionDetail says the banner appears before the first 429. At that moment rejections.total is 0, so the detail renders nothing.

The deps are [exhausted, accessToken]. exhausted stays true while webhooks are rejected, so the effect does not run again. A user who watches the quota run out sees no counts until the page reloads or the token refreshes.

Re-fetch on an interval while exhausted is true (for example every 60 s). Clear the interval in the effect cleanup. Alternatively, accept this and document it. The PR notes already describe the same limitation for the email.

- Line 61: Update getUsageForUser so failures from getQuotaRejections do not
abort the usage response: initialize quotaRejections to NO_QUOTA_REJECTIONS,
attempt the lookup only when exhausted, and report lookup errors with
reportError while preserving the fallback. Import reportError from the existing
observability module if needed.

Review comments at
@apps/web/tests/integration/supabase-quota-rejections.test.ts:
- Around line 231-242: Update the initial quotaRejections.total assertion in the
“is only included in usage while the quota is exhausted” test to use the
expected rejected-webhook total from rejections(userId), so the test passes
independently of whether the team-sharing test runs.
