Summary

Skip authMiddleware for /api/webhooks/* routes, matching the existing skip for /api/auth/*
Fixes root cause: webhook routes registered at app level were still being hit by api.use("*", authMiddleware) because the skip condition only covered /api/auth/

Root Cause

The telnyx webhook handler at /api/webhooks/telnyx/messaging returned 401 for all requests including those with valid signatures. The webhook route was registered at the app level before the api sub-app (where authMiddleware is applied), but authMiddleware only had a skip condition for /api/auth/ — not /api/webhooks/. This caused Better-Auth's session check to intercept and reject requests before they reached the signature validation logic.

Test Plan

TypeScript compiles clean (pnpm typecheck)
Re-run verify_telnyx_webhook.py against UAT after deploy — expect 4/4 pass
Confirm invalid/missing signature requests still return 401

## Summary - Skip `authMiddleware` for `/api/webhooks/*` routes, matching the existing skip for `/api/auth/*` - Fixes root cause: webhook routes registered at app level were still being hit by `api.use("*", authMiddleware)` because the skip condition only covered `/api/auth/` ## Root Cause The telnyx webhook handler at `/api/webhooks/telnyx/messaging` returned 401 for all requests including those with valid signatures. The webhook route was registered at the app level before the `api` sub-app (where `authMiddleware` is applied), but `authMiddleware` only had a skip condition for `/api/auth/` — not `/api/webhooks/`. This caused Better-Auth's session check to intercept and reject requests before they reached the signature validation logic. ## Test Plan - [x] TypeScript compiles clean (`pnpm typecheck`) - [ ] Re-run `verify_telnyx_webhook.py` against UAT after deploy — expect 4/4 pass - [ ] Confirm invalid/missing signature requests still return 401 🤖 Generated with [Claude Code](https://claude.com/claude-code)

QA Review: APPROVED

Code review: PASS

Diff is minimal and targeted: 2-line change adding || path.startsWith("/api/webhooks/") to the authMiddleware skip condition
Matches the existing pattern for /api/auth/ — correct and consistent
Root cause analysis is accurate: Better-Auth session check was intercepting webhook requests before HMAC signature validation

CI: All checks pass

Lint & Typecheck: ✅ PASS
Unit Tests: ✅ PASS
Build: ✅ PASS
E2E Tests: ✅ PASS

Risk: Low — change only widens the auth bypass for server-to-server webhook routes; all user-facing auth flows remain protected.

Ready to merge to dev. Handing to CTO for final sign-off.

CTO review: approved. Minimal, correct fix — adds /api/webhooks/ to authMiddleware skip condition alongside existing /api/auth/ skip. Root cause (Better-Auth session check intercepting webhook requests) is accurately diagnosed. No security risk — webhook routes have their own HMAC signature validation. All CI green.
