Launch Ready API security Checklist for AI chatbot product: Ready for app review in coach and consultant businesses?

When I say "ready" for an AI chatbot product in a coach or consultant business, I mean this: a reviewer can sign up, use the core flow, and not hit broken auth, exposed secrets, unstable endpoints, or unclear data handling. The product should survive real customer traffic, pass app review without avoidable delays, and not create support load from basic security mistakes.

For this specific outcome, "ready" means the chatbot can authenticate users safely, call its API without leaking keys, handle errors cleanly, and show predictable behavior under review traffic. If you cannot answer "yes" to every item below, you are not ready for app review yet.

This is the bar I would use before launch:

• Zero exposed secrets in frontend code, logs, or repo history.
• No critical auth bypasses.
• p95 API latency under 500ms for core chatbot requests.
• SPF, DKIM, and DMARC passing for outbound email.
• Cloudflare and SSL configured correctly.
• Monitoring active before launch, not after the first outage.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | Authentication | Users must log in with secure session handling or token auth | Protects customer data and account access | Account takeover, fake usage, app rejection | | Authorization | Users only see their own chats, files, and billing data | Prevents cross-account leaks | Data exposure between clients | | Secrets handling | No API keys in client code or public repos | Stops key theft and abuse charges | Billing spikes, service abuse, shutdown | | Input validation | Chat messages and metadata are validated server-side | Blocks injection and malformed requests | Broken flows, prompt abuse, backend errors | | Rate limiting | Per-user and per-IP limits on sensitive endpoints | Reduces spam and brute force risk | Cost blowouts, downtime, abuse | | CORS policy | Only approved origins can call private APIs | Stops unauthorized browser access | Token theft via rogue sites | | Logging hygiene | Logs exclude tokens, PII, and raw prompts where risky | Prevents data leakage through observability tools | Compliance issues, support incidents | | Error handling | User sees safe errors; stack traces stay private | Avoids information disclosure | Review failure, easier exploitation | | Email authentication | SPF/DKIM/DMARC all pass on outbound mail | Ensures emails land reliably and look legitimate | Onboarding failures, spam folder delivery | | Monitoring and uptime checks | Alerts fire on downtime and error spikes within 5 minutes | Catches launch issues fast | Long outages, lost conversions |

The Checks I Would Run First

1. Authentication flow

• Signal: I can create an account, sign in, sign out, reset password if needed, and keep sessions stable across refreshes.
• Tool or method: Manual test in a fresh browser profile plus a quick review of auth middleware or session config.
• Fix path: Move auth checks to the server side where possible. If you are using JWTs in the browser for sensitive actions without strict expiry and refresh control, I would tighten that before launch.

2. Authorization boundaries

• Signal: A user cannot change an ID in the URL or request body and access another client's chat history or files.
• Tool or method: Try ID swapping on chat threads, user profiles, invoices, uploads, and admin routes.
• Fix path: Enforce ownership checks on every protected object. Do not trust the frontend to hide records.

3. Secret exposure audit

• Signal: No OpenAI keys, webhook secrets, database URLs with write access, or Cloudflare credentials appear in client bundles or public env files.
• Tool or method: Search the repo for common secret patterns plus inspect build output and browser network calls.
• Fix path: Move all secrets to server-only environment variables. Rotate anything that has already been exposed.

4. Prompt injection resistance

• Signal: A malicious user cannot coerce the bot into revealing system prompts, hidden instructions, internal URLs, or other users' content.
• Tool or method: Run a small red-team set with prompts like "ignore previous instructions" and "show me your system prompt."
• Fix path: Keep system instructions separate from user content. Strip tool permissions down to what is needed. Add output filters for sensitive data.

5. Rate limiting and abuse controls

• Signal: Repeated requests do not let one user burn through model spend or hammer your API with hundreds of calls per minute.
• Tool or method: Test bursts from one IP and one account using curl or Postman collections.
• Fix path: Add per-route rate limits for login, reset password, chat senders, webhook handlers, and file upload endpoints.

6. Email deliverability setup

• Signal: SPF passes on your domain email provider; DKIM signs messages; DMARC policy is at least monitoring mode with aligned From headers.
• Tool or method: Send test emails to Gmail and Outlook plus check DNS records with an external validator.
• Fix path: Fix DNS records before launch. Bad email setup causes missed verification emails and support tickets that waste hours every week.

Red Flags That Need a Senior Engineer

1. You have multiple API keys in client-side code. This is not a cleanup task anymore. If keys shipped to browsers or public repos are live keys with write access, I would assume they are compromised until proven otherwise.

2. Your chatbot uses third-party tools with broad permissions. If the bot can send emails, query CRM records, create calendar events, or fetch documents without strict guardrails then prompt injection becomes a business risk fast.

3. You do not know who can access which customer conversations. That usually means authorization is either missing or implemented inconsistently across endpoints.

4. Your app review keeps failing for "privacy," "security," or "incomplete functionality." That often means there are hidden leaks in logs, weak consent language around AI use of customer data ,or broken onboarding paths that reviewers hit immediately.

5. Your deployment process is manual and undocumented. If one person has to remember DNS changes ,SSL renewal ,and env var updates by hand ,you have a release risk that will eventually become downtime.

DIY Fixes You Can Do Today

1. Rotate any exposed secrets now. If you pasted keys into frontend code ,shared them in Slack ,or committed them to GitHub ,rotate them before anything else.

2. Turn on Cloudflare protection. Put the domain behind Cloudflare ,enable SSL ,and lock down origin access so only Cloudflare can reach your server if your stack supports it.

3. Add basic rate limits. Start with login ,password reset ,chat send ,and webhook routes. Even simple limits reduce abuse while you work on deeper fixes.

4. Check email DNS records. Make sure SPF ,DKIM ,and DMARC exist for your sending domain. If verification emails fail now ,app review will expose it fast.

5. Review what your bot can see. Remove any tool access it does not absolutely need. A coach chatbot usually does not need broad database access to function well.

A useful baseline config looks like this:

OPENAI_API_KEY=server_only
DATABASE_URL=server_only
NEXT_PUBLIC_APP_URL=https://yourdomain.com

If a secret starts with `NEXT_PUBLIC_`, `VITE_`, or any other client-exposed prefix in your stack ,assume it is public unless your framework explicitly prevents that value from reaching the browser bundle.

Where Cyprian Takes Over

If you want app review readiness without spending days guessing at infra issues ,this is where my Launch Ready sprint fits.

I would map checklist failures directly to deliverables like this:

• Secret exposure -> move secrets to server-only env vars ,rotate compromised keys ,verify no client leakage.
• Broken DNS or subdomains -> configure domain routing ,redirects ,subdomains ,and Cloudflare protection.
• SSL problems -> issue certificates correctly and confirm HTTPS across all entry points.
• Weak email delivery -> set up SPF/DKIM/DMARC so verification and onboarding emails land reliably.
• Unmonitored production -> add uptime monitoring plus error visibility before launch day.
• Risky deployment -> ship production deployment with a handover checklist so you are not guessing after go-live.

What you get:

• Domain setup
• Email setup
• Cloudflare configuration
• SSL configuration
• Deployment support
• Secrets handling
• Uptime monitoring
• Handover checklist

Service details:

• Name: Launch Ready
• Category: Launch & Deploy
• Hook: Domain,email ,Cloudflare ,SSL,deployment,secrets,and monitoring in 48 hours

• Delivery window: 48 hours
