How I Would Fix exposed API keys and missing auth in a GoHighLevel mobile app Using Launch Ready.

Opening

If I see exposed API keys and missing auth in a GoHighLevel mobile app, I assume two things first: the app was shipped too early, and the backend trust model is broken. The business risk is not abstract. It means unauthorized access, customer data exposure, surprise usage bills, support tickets, and a real chance the app gets pulled or blocked before users can rely on it.

The most likely root cause is that the app is calling GoHighLevel or related APIs directly from the mobile client with secrets baked into the bundle, and there is no server-side authorization layer enforcing who can do what. The first thing I would inspect is the live build artifact and network traffic from the app, because that tells me whether the secret is actually embedded client-side or only leaked in logs, screenshots, or misconfigured environment files.

I would treat this as a production incident, not a cosmetic bug. For a founder, this is usually a 48-hour containment problem before it becomes a reputation problem.

Triage in the First Hour

1. Check whether any API keys are visible in the mobile bundle.

• Inspect compiled JavaScript, source maps, config files, and any `.env` references.
• Search for GoHighLevel tokens, private keys, webhook secrets, and admin credentials.

2. Review recent deploys and build outputs.

• Look at the last 3 builds.
• Confirm whether secrets were added to frontend code by mistake.
• Check if source maps are publicly accessible.

3. Open network logs from the app.

• Verify which endpoints are called directly from the client.
• Note whether sensitive actions happen without an authenticated session token.

4. Audit authentication screens and route guards.

• Check login flow, token storage, session refresh, and logout behavior.
• Confirm whether protected screens can be opened after clearing auth state.

5. Inspect GoHighLevel account permissions.

• Identify whether the key has full account access or limited scope.
• Rotate anything that looks like a long-lived secret exposed in client code.

6. Review Cloudflare and hosting logs if available.

• Look for unusual request spikes.
• Check for anonymous access to endpoints that should require auth.

7. Verify environment variable handling.

• Confirm secrets are injected at build time only on trusted servers.
• Make sure nothing sensitive is committed to git or shipped to mobile clients.

8. Check monitoring alerts and error logs.

• Look for repeated 401, 403, 429, or unexpected 200 responses on protected routes.

A quick search I would run immediately:

grep -RniE "api[_-]?key|secret|token|gohighlevel|ghl" .

That does not fix anything by itself. It just tells me where the leak might be hiding so I can contain it fast.

Root Causes

1. Secrets were hardcoded into the mobile app.

• How I confirm it: inspect compiled assets, source maps, repo history, and any config files bundled into the app.
• Common sign: an API key appears in network requests or decompiled app resources.

2. The app talks directly to third-party APIs from the client.

• How I confirm it: review network calls and see whether requests go straight from mobile to GoHighLevel instead of through your backend.
• Common sign: no server-side session check before sensitive actions.

3. Authentication exists visually but not functionally enforced.

• How I confirm it: log out or clear local storage and try opening protected screens or performing write actions.
• Common sign: UI hides buttons but endpoints still accept requests without verifying identity.

4. Token storage is insecure or inconsistent.

• How I confirm it: inspect how tokens are stored on device and whether they persist after logout or reinstall.
• Common sign: stale sessions still work after password reset or user removal.

5. Environment separation is broken.

• How I confirm it: compare dev, staging, and production configs for shared keys or reused credentials.
• Common sign: one leaked key works across multiple environments.

6. Backend endpoints lack authorization checks.

• How I confirm it: test each sensitive endpoint with no token, expired token, and another user's token in a safe QA environment.
• Common sign: endpoints return data even when auth should fail.

The Fix Plan

My recommendation is to stop treating the mobile app as trusted infrastructure. The fix path is to move all sensitive operations behind a server-owned API layer and rotate every exposed secret before redeploying anything else.

1. Contain first.

• Rotate every exposed key immediately in GoHighLevel and any connected services.
• Revoke old tokens where possible.
• Disable public access to any leaked config file or source map.

2. Remove secrets from the mobile client.

• Delete hardcoded keys from app code, env files shipped to clients, and build-time constants that end up in bundles.
• If something must be public on device, treat it as non-secret by design.

3. Introduce a backend proxy layer for sensitive actions.

• The mobile app should authenticate against your backend first.
• Your backend then calls GoHighLevel using server-side credentials stored in environment variables or secret manager storage.

4. Enforce auth on every protected route and action.

• Require valid session tokens for reads that expose personal data and all writes that change records or trigger workflows.
• Add role checks if admins and end users have different permissions.

5. Lock down CORS, rate limits, and request validation.

• Allow only expected origins where relevant for web surfaces tied to the same product stack.

For mobile APIs, validate tokens rather than trusting origin alone because origin checks are not enough on their own.

• Reject malformed payloads early with schema validation.

6. Harden deployment handling through Launch Ready standards.

• Put DNS behind Cloudflare where appropriate for web surfaces supporting the mobile product ecosystem.
• Enable SSL everywhere external traffic touches your stack.
• Set up SPF/DKIM/DMARC if email delivery is part of onboarding or notifications so support does not inherit deliverability problems later.

7. Move secrets into proper runtime storage. This means environment variables on trusted infrastructure only:

GOHIGHLEVEL_API_KEY=replace_me
GOHIGHLEVEL_LOCATION_ID=replace_me
JWT_SECRET=replace_me

8. Add monitoring before shipping again.

• Alert on auth failures spiking above baseline by 20 percent within 15 minutes of deploys.

That often catches broken login flows before customers do? No; keep it clean:

• Alert on auth failures spiking above baseline by 20 percent within 15 minutes of deploys
• Track unusual API usage volume
• Log denied requests without recording secrets
• Watch p95 latency so proxying through your backend does not turn into a slow app

9. Ship in small steps only after verification. The safest order is rotate -> remove client secrets -> add backend auth -> test -> redeploy -> monitor for 24 hours. Anything else creates more blast radius than you need right now.

Regression Tests Before Redeploy

I would not redeploy until these checks pass in staging with production-like data shape but no live secrets exposed to testers.

• Auth required test:
• Attempt protected actions with no session token

-, expected result: 401 or redirect to login

• Expired token test:

-, expected result: forced re-authentication

• Cross-user access test:

-, expected result: user A cannot read user B records

• Secret scan test:

-, expected result: zero API keys found in bundled assets

• Logout test:

-, expected result: cached sessions are invalidated correctly

• Rate limit test:

-, expected result: abusive retries get throttled without breaking normal use

• Error handling test:

-, expected result: failed upstream calls show safe messages with no secret leakage

• Mobile install test:

-, expected result: fresh install starts unauthenticated

• Upgrade test:

-, expected result: existing users keep working after token rotation if intended

Acceptance criteria I would use:

| Area | Pass condition | | --- | --- | | Auth | No protected endpoint works without valid session | | Secrets | No secret appears in bundle, logs, screenshots, or source maps | | Data access | Users only see their own records | | Stability | p95 API response stays under 500 ms for normal flows | | Monitoring | Alerts fire within 5 minutes of repeated failures |

I would also run one manual exploratory pass on iOS and Android if both are supported. Broken auth often shows up differently across platforms because of storage behavior and background refresh timing.

Prevention

The best prevention here is boring engineering discipline applied consistently.

• Keep all third-party API credentials server-side only.
• Use short-lived tokens for user sessions instead of permanent access keys in clients where possible?

No; make it direct:

• Use short-lived user tokens instead of permanent access keys in clients where possible
• Review every release for secret exposure before App Store or Play Store submission
• Add automated secret scanning in CI so leaks fail builds before merge
• Require code review for any endpoint touching customer data
• Log authorization failures separately from general errors so abuse patterns stand out
• Put rate limits on login, password reset, webhook intake, and high-value write endpoints
• Strip source maps from public hosting unless you have a controlled reason to expose them
• Test empty states and logged-out states so UX does not encourage unsafe shortcuts like "temporary admin bypass"
• Monitor p95 latency after adding proxy layers so security fixes do not create slow onboarding or abandoned checkout flows

For GoHighLevel specifically, I would also document which parts of your product are allowed to talk directly to GHL tools versus which parts must go through your own backend. If that boundary is unclear now, it will get violated again later by whoever ships next fastest under pressure.

When to Use Launch Ready

Use Launch Ready when you need this contained fast without turning your team into part-time infrastructure engineers. Wait keep clean:

Use Launch Ready when you need domain setup? But product type mobile app maybe supportive web assets? Mention deployment/secrets/monitoring/handover aligned with hook.

Use Launch Ready when you need me to handle domain routing for supporting web assets,, Cloudflare,, SSL,, deployment,, secrets,, monitoring,,and handover inside two days while you focus on users and support load reduction?

Let's craft final paragraph:

Use Launch Ready when you need me to secure deployment plumbing around the app fast: DNS where needed for supporting web surfaces,, redirects,, subdomains,, Cloudflare,, SSL,, caching,, DDoS protection,, SPF/DKIM/DMARC,, production deployment,, environment variables,, secrets handling,, uptime monitoring,,and a handover checklist that your team can actually follow?

Need exact wording concise:

Launch Ready fits when your product works but its launch plumbing is unsafe or unfinished." Good enough.

Before booking it ready? prepare list:

Prepare repo access,,, current hosting/provider logins,,, GoHighLevel workspace details,,, list of environments,,, current domains,,, email provider details,,, list of exposed keys already rotated?,,,, analytics/admin access,,,and one person who can approve changes quickly during the sprint."
