Web Service Onboarding Skill#

The Core Pattern#

text

Send signup email → Verify email → Complete registration →
Generate API keys → Store securely in 1Password → Wire .env

Do this in a single unbroken browser session. Never close the browser between steps.

---

Critical Rules (Learned the Hard Way — Turnkey, 2026-03-25)#

1. One session, no gaps#

• Complete signup AND API key creation AND secret storage in the same browser session
• Close the browser only after credentials are saved to 1Password
• If the browser closes before credentials are extracted, you've lost access — the passkey/session is gone

2. Email alias trap#

• Proton Mail (and many providers) treat user+alias@domain.com as the same user
• If the service already has an account for user@domain.com, the alias will route to that existing account
• Always check whether the service resolves aliases before using them for a fresh account
• Use a completely different email (different domain, different provider) for a truly separate account

3. WebAuthn virtual authenticator is ephemeral#

• Playwright's WebAuthn.addVirtualAuthenticator creates an in-memory credential store

• The passkey it registers is only valid for that browser process

• If you close the browser and reopen it, the credential is gone forever

• The only way to reuse it is to export the credential before closing, then re-import on next run

• Export immediately after registration: js

  const creds = await cdp.send('WebAuthn.getCredentials', { authenticatorId });
  fs.writeFileSync('/tmp/webauthn-creds.json', JSON.stringify(creds));
  
  

• Re-import on next session: js

  const saved = JSON.parse(fs.readFileSync('/tmp/webauthn-creds.json'));
  for (const cred of saved.credentials) {
    await cdp.send('WebAuthn.addCredential', { authenticatorId, credential: cred });
  }
  
  

4. Email verification is link-based, not always OTP#

• Don't assume OTP input fields — check the actual email body first
• Turnkey, Vercel, Railway, Render all send magic links not codes
• Parse the email body with quoted-printable decoding before extracting URLs
• Watch for soft line breaks ( =\n) in QP-encoded emails

5. Session cookies are tied to the authenticator#

• If you complete signup in context A and try to use the session in context B, it won't work
• Cookies + passkey credential must stay in the same browser context

6. Internal APIs are not public APIs#

• app.service.com/internal/api/* endpoints require session cookies
• api.service.com/public/v1/* endpoints require API key stamping
• You can't call public API endpoints to bootstrap if you have no API key yet
• Only the internal API (cookie-auth) is accessible from an authenticated browser session

---

Workflow#

Phase A: Send signup email (clean context — no cookies)#

js

const ctxClean = await browser.newContext({ storageState: undefined });
const page = await ctxClean.newPage();
await page.goto('https://service.com/signup');
// fill email, click continue
// close ctxClean immediately after submitting
await ctxClean.close();

Why separate? Prevents existing session cookies from hijacking the signup flow.

Phase B: Complete signup + save API keys (same context throughout)#

js

const ctx = await browser.newContext({ storageState: undefined });
const page = await ctx.newPage();
const cdp = await ctx.newCDPSession(page);

// Set up virtual authenticator BEFORE navigating
await cdp.send('WebAuthn.enable', { enableUI: false });
const { authenticatorId } = await cdp.send('WebAuthn.addVirtualAuthenticator', {
  options: {
    protocol: 'ctap2', transport: 'internal',
    hasResidentKey: true, hasUserVerification: true,
    isUserVerified: true, automaticPresenceSimulation: true,
  }
});

// Navigate to verify link
await page.goto(verifyUrl);

// Complete signup steps...

// IMMEDIATELY export credential after passkey registration
const creds = await cdp.send('WebAuthn.getCredentials', { authenticatorId });
fs.writeFileSync('/tmp/webauthn-creds.json', JSON.stringify(creds));
console.log('Credentials backed up:', creds.credentials?.length);

// Continue to API key + wallet creation IN SAME SESSION
// ...save API keys...

// Close browser ONLY after saving everything to 1Password

Email Fetching via Proton Bridge IMAP#

js

function fetchLatestTurnkeyLink(host='127.0.0.1', port=1143, user, pass) {
  return new Promise((resolve) => {
    const socket = net.connect(port, host);
    let buf='', tls2=null, step=0, body=[], inBody=false;
    const t = setTimeout(() => { try{(tls2||socket).destroy()}catch(e){}; resolve(null); }, 22000);
    function send(cmd) { (tls2||socket).write(cmd+'\r\n'); }
    function onData(data) {
      buf += data.toString();
      const lines = buf.split('\r\n'); buf = lines.pop();
      for (const l of lines) {
        if (inBody) body.push(l);
        if (step===0 && l.includes('OK')) { step=1; send('a1 STARTTLS'); }
        else if (step===1 && l.includes('a1 OK')) { tls2=tls.connect({socket,rejectUnauthorized:false}); tls2.on('data',onData); step=2; send(`a2 LOGIN "${user}" "${pass}"`); }
        else if (step===2 && l.includes('a2 OK')) { step=3; send('a3 SELECT INBOX'); }
        else if (step===3 && l.includes('a3 OK')) { step=4; send('a4 SEARCH ALL'); }
        else if (step===4 && l.startsWith('* SEARCH')) {
          const nums = l.replace('* SEARCH','').trim().split(' ').filter(Boolean);
          step=5; inBody=true; send(`a5 FETCH ${nums[nums.length-1]} (BODY[TEXT])`);
        }
        else if (step===5 && l.includes('a5 OK')) {
          clearTimeout(t); (tls2||socket).end();
          // Decode quoted-printable
          const decoded = body.join('\n')
            .replace(/=\r?\n/g, '')
            .replace(/=([0-9A-Fa-f]{2})/g, (_, h) => String.fromCharCode(parseInt(h, 16)));
          // Extract redirect URLs
          const urls = [...decoded.matchAll(/https:\/\/service\.com\/redirect\?token=[^\s"<>)]+/g)].map(m=>m[0]);
          resolve(urls[0] || null);
        }
      }
    }
    socket.on('data', onData);
    socket.on('error', () => { clearTimeout(t); resolve(null); });
  });
}

Key: Pattern-match the redirect URL to the service's domain, not a generic URL.

Proton Mail Setup#

• IMAP host: 127.0.0.1, port: 1143, STARTTLS
• Credentials in 1Password: op://OpenClaw/Proton Bridge - Monk Fenix/...
• Bridge must be running: ps aux | grep -i bridge

---

Input/Form Filling — Use Native Value Setter#

Standard element.fill() sometimes fails on React inputs. Use this:

js

await page.evaluate((value) => {
  const input = document.querySelector('input');
  Object.getOwnPropertyDescriptor(window.HTMLInputElement.prototype, 'value')
    .set.call(input, value);
  input.dispatchEvent(new Event('input', { bubbles: true }));
  input.dispatchEvent(new Event('change', { bubbles: true }));
}, value);

---

Button Clicking — Scroll Into View First#

Buttons outside viewport fail with element is outside of the viewport. Always scroll:

js

await page.evaluate((text) => {
  const btn = [...document.querySelectorAll('button')]
    .find(b => b.textContent?.toLowerCase().includes(text) && !b.disabled);
  if (btn) { btn.scrollIntoView(); btn.click(); }
}, buttonText);

---

After Successful Authentication — save API keys#

For services with internal browser APIs:

js

// Call authenticated internal API from page context
const data = await page.evaluate(async () => {
  const r = await fetch('/internal/api/v1/whoami');
  return r.json();
});
// data.organizationId, data.userId, etc.

---

Creating API Keys / Resources via Internal API#

Once authenticated (cookie present), call internal endpoints from the page context:

js

const result = await page.evaluate(async ({ orgId, publicKey }) => {
  const r = await fetch('/tkhq/api/v1/activities', {  // adjust per service
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
      type: 'ACTIVITY_TYPE_CREATE_API_KEYS',
      organizationId: orgId,
      parameters: { apiKeys: [{ apiKeyName: 'my-key', publicKey, curveType: 'API_KEY_CURVE_P256' }] }
    })
  });
  return { status: r.status, body: await r.text() };
}, { orgId, publicKey });

Important: Internal endpoints vary per service. Before creating resources, capture network traffic to learn the real endpoint:

js

page.on('request', req => {
  if (req.method() !== 'GET' && req.url().includes(serviceDomain))
    console.log(req.method(), req.url());
});

Saving to 1Password#

bash

op item create \
  --vault OpenClaw \
  --title "Turnkey API Credentials — Reddi Agent Protocol" \
  --category "API Credential" \
  "org_id[text]=$ORG_ID" \
  "user_id[text]=$USER_ID" \
  "api_public_key[text]=$API_PUB" \
  "api_private_key[password]=$API_PRIV" \
  "wallet_id[text]=$WALLET_ID" \
  "wallet_address[text]=$WALLET_ADDR"

---

Signup Registry (MANDATORY)#

Before starting any signup, add an entry to the Notion signup registry:

• DB: 322eb552-581a-81dc-adbc-fabb7af1d311
• Fields: service name, email used, date, purpose
• This is non-negotiable per POLICIES.md

---

Service-Specific Notes#

Turnkey ( app.turnkey.com)#

• Email verify: link-based (magic link, not OTP)
• Auth: WebAuthn passkey (virtual authenticator works)
• Post-signup API: /tkhq/api/v1/activities (internal, cookie-auth)
• Public API: api.turnkey.com/public/v1/ requires X-Stamp (signed request)
• Email aliases ( +tag) map to the same Turnkey account — use a different provider for separate orgs
• Org created in one run: b7378687-cf82-45ab-a46c-7dda9239001d (Reddi Agent Protocol)

Generic patterns#

• Vercel: email OTP or GitHub OAuth
• Railway: GitHub OAuth (no email signup)
• Supabase: email + password, then API key in dashboard
• Fly.io: email + credit card, CLI bootstrap preferred

---

Pre-flight Checklist#

Before starting any signup:

• Added to Notion signup registry
• Confirmed email available (not already used for this service)
• Email aliases: does service collapse them? (test first)
• IMAP readable for email provider being used
• 1Password vault accessible
• Proton Bridge running (if using Proton)
• Sufficient budget for paid tier (if applicable) — ask Nissan first
