Webhook lifecycle: GET hub.challenge handshake (constant-time verify-token compare); POST verifies X-Hub-Signature-256 over the RAW body before any parse, Zod-parses the envelope, persists inbound rows (partial-unique wamid = dedupe against Meta's up-to-7-day redelivery), acks 200 fast and defers media processing via the after() idiom. Rejected and rate-limited content always acks 200 and lands as skipped/error rows, never a retryable status. Linking: the settings panel (Installningar -> WhatsApp) mints AC- one-time codes (sha256 stored, 10 min TTL, single use, ambiguity-free alphabet); the webhook consumes the code, binds phone to user (HMAC-peppered hash + AES-256- GCM at rest) and confirms with M3. Keyword commands stopp/start/hjalp; unknown senders get one throttled M1 greeting (1/h, 3/day) behind the sender-quota RPC, with no media download and no content persistence. Intake worker: atomic claim on the message row (the durable job record), company resolution (default -> sole membership -> M6 fallback, no item), per-company inbox quota (ack-and-drop, M17 once per 10 min per sender), MIME allowlist, 10 MB stream-checked media download, exact sha256 duplicate check, then the shared uploadAndExtract funnel (source 'whatsapp', channel_context caption, whatsapp_message_id) and the M4 ack with extracted merchant/total/date. Failures wrap to 'error' + error_message + one M18. uploadAndExtract widened: source 'whatsapp', optional channelMeta + actorId; email/upload paths behaviorally unchanged. Deferred to PR4: burst debounce + combined ack (M5), in-chat company choice (M6 buttons + 8h pin), clarifying questions M7-M10, interpret-answer LLM call, sweep cron, retention cron.

Whitelabel fork checklist
Accounted is whitelabel-friendly: every user-visible brand reference reads from a single BrandingService (lib/branding/service.ts). If you don't override anything, the app behaves exactly like upstream gnubok. To run your own brand on top of Accounted, fork the repo and override the values you care about.
Quick start
# 1. Fork erp-mafia/gnubok on GitHub → you/your-brand
# 2. Clone and add upstream remote (one-time)
git clone https://github.com/you/your-brand
cd your-brand
git remote add upstream https://github.com/erp-mafia/gnubok
# 3. Copy the example branding extension
cp -r extensions/general/_example-branding extensions/general/your-brand
# Edit extensions/general/your-brand/index.ts with your brand values
# 4. (Optional) Set env vars instead of / in addition to the extension. See "Env vars" below.
# 5. Enable the extension
# Edit extensions.config.json and add "your-brand" to the array.
# 6. Run locally
npm run setup:extensions
npm run dev
# 7. Deploy to your hosting (Vercel, Docker, etc.)
Env vars
All branding can be set via env vars. Public ones use NEXT_PUBLIC_BRANDING_* (build-time inlined, available in client components). Server-only ones use BRANDING_*.
| Env var | Field | Default |
|---|---|---|
NEXT_PUBLIC_BRANDING_APP_NAME |
appName |
Accounted |
NEXT_PUBLIC_BRANDING_APP_DESCRIPTION |

BRANDING_SECURITY_EMAIL |
securityEmail |
security@arcim.io |
NEXT_PUBLIC_BRANDING_AUTH_EMAIL_FROM |
authEmailFrom: From address Supabase Auth sends verification / reset emails from. Used to pre-populate the from: query on the "open in Gmail" button after signup. Set to whatever you configured in your Supabase Auth SMTP. |

Resolution order (last wins): defaults → env vars → extension override.
NEXT_PUBLIC_* env vars are inlined at build time. Changing them requires a fresh npm run build to propagate.
NEXT_PUBLIC_BRANDING_APP_NAME also stamps the service worker push-notification fallback title in public/sw.js. This happens at build time for Vercel/local builds (via scripts/inject-public-branding.mjs, run from prebuild) and at container start for Docker (via docker-entrypoint.sh).
Email / Resend (when email or invoice-inbox extensions are enabled)
| Env var | Purpose |
|---|---|
RESEND_API_KEY |
Resend API key: required for both outbound mail and the inbox webhook |
RESEND_FROM_EMAIL |
Default From address (e.g. noreply@your-brand.se); also used as the address you From-spoof through Resend |
RESEND_INBOUND_DOMAIN |
Domain used to compose per-company invoice-inbox addresses: {local-part}@{RESEND_INBOUND_DOMAIN} |
RESEND_INBOUND_WEBHOOK_SECRET |
Verifies the /inbound webhook signature from Resend |
RESEND_DELIVERY_WEBHOOK_SECRET |
Verifies the /delivery-status webhook signature from Resend. Optional: without it, invoice delivery history shows "sent" but never the delivery outcome |
WhatsApp (when the whatsapp-inbox extension is enabled)
| Env var | Purpose |
|---|---|
WHATSAPP_ACCESS_TOKEN |
Meta system-user permanent token (whatsapp_business_messaging scope only) |
WHATSAPP_PHONE_NUMBER_ID |
Graph object id of your WhatsApp Business number |
WHATSAPP_APP_SECRET |
Verifies X-Hub-Signature-256 on the /webhook POST |
WHATSAPP_VERIFY_TOKEN |
Shared secret for the GET subscription handshake (also entered in the Meta app dashboard) |
WHATSAPP_PHONE_HASH_KEY |
Random pepper for phone lookup hashes (openssl rand -hex 32) |
WHATSAPP_PHONE_ENCRYPTION_KEY |
32-byte hex AES-256-GCM key for phone numbers at rest (openssl rand -hex 32) |
WHATSAPP_PUBLIC_NUMBER |
Optional: the public number as E.164 digits (e.g. 46766867041) for the wa.me deep link in settings; unset = resolved from the Graph API |
Things you MUST NOT change
These are stable contracts. Renaming them breaks existing data, sessions, or external clients (npm package consumers, MCP connectors, browser sessions, invite links). Leave them alone in your fork:
| Identifier | Where | Why |
|---|---|---|
gnubok-company-id |
cookie | Active company context: renaming breaks logged-in sessions |
gnubok-invite-token |
cookie | Pre-auth invite token holding: renaming drops in-flight invites |
gnubok_sk_ |
API key prefix | All issued API keys; existing clients fail validation |
gnubok_inv_ |
invite token prefix | All sent invite links break |
gnubok_* |
MCP tool names (gnubok_list_invoices, etc.) |
Published MCP API: Claude clients have these cached |
gnubok-mcp |
npm package name | Whitelabel users still install npx gnubok-mcp. Document GNUBOK_URL=https://app.your-brand.se/api/extensions/ext/mcp-server/mcp so they hit your endpoint |
GNUBOK_API_KEY |
env var read by gnubok-mcp package |
Same reason: npm consumer expects this name |
What's outside this branding service
A few things that look brand-related but are configured elsewhere:
- Supabase auth emails (password reset, magic link): set in the Supabase dashboard for your project, not in code.
- Resend sending domain: verify
noreply@your-brand.se(or wherever) in Resend, setRESEND_FROM_EMAIL. - DNS / domain: point
app.your-brand.seat your Vercel deployment. - OAuth redirect allowlist for MCP:
app/api/mcp-oauth/authorize/route.tslistsclaude.ai/api/*,claude.com/api/*, and localhost. Your domain is the OAuth issuer, not a redirect target: no change needed unless you're integrating with new MCP clients. - iCal feed PRODID (
lib/calendar/ics-generator.ts): defaults toerp-base.se, callers may pass their domain. NEXT_PUBLIC_APP_URL: used as the OAuth issuer. Set this to your domain (e.g.https://app.your-brand.se).- Skatteverket submission identity:
extensions/general/skatteverket/lib/api-client.tsdoes not set a customUser-Agent; submissions go out with the Node/Vercel runtime default. If your deployment needs to identify itself to Skatteverket under a different brand, that's a future enhancement (env var + header), not something the current branding service covers.
Staying in sync with upstream
Add this workflow at .github/workflows/sync-upstream.yml to your fork. It runs weekly and opens a PR with upstream changes:
name: Sync from upstream

schedule:
- cron: '0 3 * * 1' # Mondays 03:00 UTC

Conflict avoidance
The fork-friendliness of this design depends on you keeping changes confined to your branding extension folder. Every file you edit in lib/, app/, or components/ becomes a potential conflict on the next upstream merge. If you find yourself wanting to override something the branding service doesn't expose, prefer:
- Open an upstream issue: the branding service is intentionally minimal; missing fields can be added.
- PR a hook upstream: extending the service or adding a registry pattern keeps your fork clean.
Verifying your whitelabel
After deploying:
- Visit
/: browser tab title shows your brand. - Visit
/loginand/register: your logo renders. - View source of
/manifest.webmanifest:name,short_name,theme_colorreflect your overrides. - Trigger an invite email: From line says
<your-brand> <noreply@...>, body uses your name. - Visit
/dpaand/privacy: legal entity and contact email are yours. - Open OAuth flow (
/api/mcp-oauth/authorize?...) from a test MCP client: consent page references your brand. - Submit support form (Settings → Support): internal subject prefix is
[<your-brand> support].
