Officex

OfficeX Platform

OfficeX is a membership-based app store. Users buy credits ($0.022 each). Apps charge credits via reserve/settle. Vendors earn credits and can request payouts.

Get your credentials at: https://officex.app/store/en/developer/

Getting Started

To use the OfficeX API, you only need one credential — your API key:

Your API key alone is sufficient for all authenticated operations. You can optionally include the User ID header for faster auth (skips a lookup), but it's not required.

# Simplest: just the API key
export OFFICEX_API_KEY="your-api-key"

# Optional: include user ID for faster auth
export OFFICEX_USER_ID="your-user-id"

AI agents can use just the OFFICEX_API_KEY to interact with the OfficeX API — installing apps, managing billing, checking balances, and orchestrating workflows across multiple apps.

Authentication

Install Secret is billing only — your app manages its own user authentication separately. The install secret handles the money, your app handles everything else.

Credit Economy

User buys credits → Treasury liability increases (zero-sum: Treasury + all wallets = 0)
App reserves credits → Locked from user wallet
App sips/settles → Credits move to app wallet
Vendor payouts → Credits converted to fiat, Treasury liability decreases

Decimal Credits

Credits support decimals. Rounding up to 1 credit ($0.022) is expensive for small operations:

Best practice: Price based on actual cost. If an API call costs $0.001, charge ~0.05 credits (with markup).

Dual Roles

A single OfficeX account can be both Consumer (install and use apps) and Vendor (create apps and earn credits).

Refs (Referral Links)

Refs are shareable referral links that users create to track signups. Each ref gets a unique 6-character slug. Content is checked by AI for safety before acceptance.

Public (No Auth):

GET    /refs/{ref_slug}                         → { ref }

Returns minimal ref info. Response depends on ref type:

• Managed ref (created via API): { ref_slug, user_id, title, full_url?, type: "managed", has_about_project, presigned_url? }
• Default profile ref (auto-assigned): { ref_slug, user_id, type: "default", has_about_project: false }

presigned_url (15-min expiry) is included only when the ref has an about_project. Use it to fetch the full ref payload (title, about_project, metadata) from S3.

Authenticated [API Key]:

POST   /users/me/refs                           → { ref }             Create new ref
GET    /users/me/refs             ?cursor=       → { refs[], pagination? }  List your refs
GET    /users/me/refs/{ref_slug}                → { ref }             Get ref detail
PATCH  /users/me/refs/{ref_slug}                → { ref }             Update ref
GET    /users/me/refs/{ref_slug}/referrals ?cursor= → { referrals[], pending[], pagination? }

Create ref — POST /users/me/refs:

// Request
{ title?: string, about_project?: string, metadata?: string, full_url?: string }
// about_project max 4000 chars. Content is AI-sanitized before acceptance.
// full_url: optional custom URL for this ref. Defaults to "https://officex.app?ref={slug}" if omitted.
// Response (201)
{ success: true, ref: { ref_slug: string, title?: string, full_url: string, created_at: string } }

List refs — GET /users/me/refs:

// Response (200) — paginated, 50 per page, newest first
{ success: true, refs: Array<{ ref_slug, title?, full_url?, created_at }>, pagination?: { cursor } }

Get ref detail — GET /users/me/refs/{ref_slug}:

// Response (200) — includes presigned S3 URL to fetch full payload
{ success: true, ref: { ref_slug, user_id, title?, full_url?, created_at, presigned_url } }

Update ref — PATCH /users/me/refs/{ref_slug}:

// Request — all fields optional, merges with existing payload
{ title?: string, about_project?: string, metadata?: string, full_url?: string }
// Response (200)
{ success: true, ref: { ref_slug, title?, full_url? } }

List referrals — GET /users/me/refs/{ref_slug}/referrals:

// Response (200) — who signed up via this ref
{
  success: true,

  pending: Array<{ user_id, email_blurred: "Pending User", created_at, active_voucher_slug? }>,
  pagination?: { cursor }
}

referrals = converted users. pending = vouchers sent but user hasn't signed up yet. Emails are blurred (e.g. j***n@gmail.com).

Referral tracking at signup: Pass ref in the OTP verification call to attribute the signup:

POST /auth/verify-otp  { email, code, ref?: string }

Errors: REF_NOT_FOUND (404), CONTENT_REJECTED (400, failed safety check), FORBIDDEN (403, not your ref)

Error Format

{ "success": false, "error": { "code": "ERROR_CODE", "message": "..." } }

App Lifecycle (Developer Guide)

1. Create Your App

Endpoint: POST /register-app [API Key]

{
  name: string,                    // Required: 3-50 chars
  description?: string,
  price_type?: "FREE" | "PAY_PER_USE" | "ONE_TIME" | "SUBSCRIPTION" | "MIXED",
  webhook_url?: string,            // HTTPS URL for lifecycle events
  suggested_rate_limits?: { max_per_hour?, max_per_day?, max_per_month?, expires_at? },
  minimum_rate_limits?: { max_per_hour?, max_per_day?, max_per_month?, expires_at? },
  subtitle?: string,               // Max 200 chars
  category?: string,               // Max 50 chars
  developer?: string,
  app_url?: string,
  iframe_url?: string,             // URL for embedded iframe experience
  support_url?: string,
  contact_email?: string,
  context_prompt?: string,         // AI agent instructions (max 5000 chars)
  documentation?: string,          // API docs for AI agent (max 500000 chars)
  pricing_lines?: string[],        // Max 10 items, 100 chars each
  tags?: string[],                 // Max 10
  icon?: { type: "emoji" | "image", content: string },
  inAppPurchases?: boolean
}
// Response (201): { success, app_id, destination_wallet_id, message }

Example:

curl -X POST https://cloud.officex.app/v1/register-app \
  -H "Content-Type: application/json" \
  -H "x-officex-user-id: $OFFICEX_USER_ID" \
  -H "x-officex-master-key: $OFFICEX_API_KEY" \
  -d '{
    "name": "Lead Enrichment Pro",
    "description": "Enrich B2B leads with company data",
    "price_type": "PAY_PER_USE",
    "subtitle": "B2B lead enrichment powered by AI",
    "category": "Marketing",
    "developer": "Acme Corp",
    "webhook_url": "https://myapp.com/webhooks/officex",
    "iframe_url": "https://myapp.com/officex",
    "documentation": "## API Reference\n\nThis app enriches leads...",
    "context_prompt": "This app enriches B2B leads. When the user asks to enrich leads, call the /enrich endpoint.",
    "suggested_rate_limits": { "max_per_hour": 50, "max_per_day": 200, "max_per_month": 2000 },
    "pricing_lines": ["5 credits per lead enrichment", "Bulk discount: 3 credits for 10+ leads"]
  }'

Each app gets a discrete wallet (destination_wallet_id). Earnings go there, not your personal wallet. documentation is injected into the AI chat agent's system prompt. context_prompt provides additional instructions for the AI agent.

2. Update Your App

Endpoint: PATCH /users/me/apps/{app_id} [API Key] — All fields optional, set to null to clear:

{
  name?, description?, price_type?, webhook_url?, iframe_url?, app_url?,
  subtitle?, category?, developer?, support_url?, contact_email?,
  context_prompt?, documentation?, pricing_lines?, tags?,
  icon?, previews?, icon_url?, preview_images?, youtube_url?,
  suggested_rate_limits?, minimum_rate_limits?, inAppPurchases?
}

3. List App's Installs (Vendor View)

Endpoint: GET /users/me/apps/{app_id}/installs [API Key]

// Response (200)
{
  success: true,
  installs: Array<{
    user_id: string, install_id: string, nickname?: string, status: string,
    installed_at: string, max_per_hour: number, max_per_day: number,
    max_per_month: number, allowed_until: number,
    usage: { hour: number, day: number, month: number }
  }>
}

Installation Flow (When Users Install Your App)

When a user installs your app, OfficeX:

1. Creates an Installation Record linking user to app
2. Generates an Install ID and Install Secret (scoped billing credentials)
3. Sets rate limits (user-specified or your suggested defaults)
4. Sets allowed_until expiry (default: 30 days, or -1 for no expiry)
5. Fires an INSTALL webhook to your webhook_url (if configured)

The install endpoint accepts both app_id (UUID) and slug (string) in the path parameter.

AI Agent tip: An agent can install an app on the user's behalf via POST /install/{app_id_or_slug} using the user's OFFICEX_USER_ID and OFFICEX_API_KEY, then use the returned install_id and install_secret for billing.

Webhook Events

Your app receives lifecycle events at webhook_url. Envelope: { event, payload, uuid }.

INSTALL Event:

{
  "event": "INSTALL",
  "payload": {
    "install_id": "uuid-of-installation",
    "install_secret": "base64url-encoded-secret",
    "user_id": "uuid-of-user",
    "app_id": "uuid-of-your-app",
    "email": "user@example.com",
    "timestamp": "2025-01-25T10:30:00Z"
  },
  "uuid": "unique-request-id"
}

UNINSTALL Event: payload: { install_id, user_id, app_id, timestamp }

RATE_LIMIT_CHANGE Event: payload: { install_id, user_id, app_id, max_per_hour, max_per_day, max_per_month, allowed_until, timestamp }

Webhook Response: Your response for INSTALL can include agent_context (only this key is extracted). Values are stored on the installation and injected into the user's AI agent prompt:

{
  "agent_context": {
    "api_key": "sk-abc123",
    "workspace_id": "ws-456",
    "base_url": "https://myapp.com/api/v1"
  }
}

Delivery: POST, application/json, 25s timeout, fire-and-forget (no retries in v1).

Credit Billing System

The Reserve → Sip → Settle Pattern

┌─────────────┐     ┌─────────────┐     ┌─────────────┐
│   RESERVE   │────►│     SIP     │────►│   SETTLE    │
│  Lock funds │     │  Progressive│     │  Finalize   │
│  for job    │     │  billing    │     │  + refund   │
└─────────────┘     └─────────────┘     └─────────────┘
                          │
                          ▼ (if job fails)
                    ┌─────────────┐
                    │   CANCEL    │
                    │  Full refund│
                    └─────────────┘

Reserve (Lock Funds)

POST /reserve [Install Secret]

// Request
{ amount: number, job_id: string, metadata?: Record<string, unknown> }
// Response (200)
{ success: true, reservation_id: string, amount_reserved: number }

curl -X POST https://cloud.officex.app/v1/reserve \
  -H "Content-Type: application/json" \
  -H "x-officex-install-id: $INSTALL_ID" \
  -H "x-officex-install-secret: $INSTALL_SECRET" \
  -d '{ "amount": 10, "job_id": "lead-enrich-job-12345", "metadata": { "leads_count": 50 } }'

Internally: user's wallet.available decreases, wallet.reserved increases, creates RESV#<job_id>.

Sip (Progressive Settlement)

POST /reservations/{reservation_id}/settle (or POST /settle) [Install Secret]

// Request (partial)
{ amount: number, final: false }
// Response (200)
{ success: true, settled_amount: number, remaining_reserved: number, status: "partial" }

Example — enriching 100 leads:

Reserve 100 credits
├── Sip 10 (processed 10 leads) → settled: 10, reserved: 90
├── Sip 10 (processed 20 leads) → settled: 20, reserved: 80
├── Sip 10 (processed 30 leads) → settled: 30, reserved: 70
└── Settle final 70 → settled: 100, reserved: 0, status: "completed"

Settle (Final)

// Request (final)
{ amount: number, final: true }
// Response (200)
{ success: true, settled_amount: number, remaining_reserved: number, status: "completed" }

Remaining reserved funds (if any) are refunded to user. Credits move to your app's wallet.

Cancel (Full Refund)

POST /reservations/{reservation_id}/cancel [Install Secret]

// Response (200)
{ success: true, refunded_amount: number, status: "cancelled" }

Rate Limits & Allowances

Rate limits are per (user, app) pair — each installation has independent limits.

Minimum rate limits (developer-set floor): Users cannot go below these values.

allowed_until: Unix timestamp (-1 = never expires, default = now + 30 days). When expired, all /reserve calls fail with INSTALL_EXPIRED. Enables pseudo-subscription billing.

lifetime_spend_limit: Total credits an app can ever charge across all time. Set to -1 for unlimited. Fails with LIFETIME_LIMIT_REACHED when exceeded.

Agent Context (AI Chat Integration)

OfficeX has a built-in AI chat agent that can orchestrate actions across installed apps. When users chat with OfficeX AI, the agent receives your app's documentation and context_prompt. This enables the agent to call your app's API endpoints, trigger workflows, and chain operations across multiple apps.

Store per-install credentials via:

PATCH /users/me/installs/{install_id}/context [API Key] or PATCH /installs/{install_id}/context [Install Secret]

// Request: Record<string, string | null> (null deletes key)
{ "api_key": "sk-abc123", "workspace_id": "ws-456" }
// Response (200)
{ success: true, agent_context: { "api_key": "sk-abc123", "workspace_id": "ws-456" } }

Validation: Max 50 keys, 200 chars/key, 1000 chars/value.

Best practice: Return credentials in INSTALL webhook response → auto-applied as agent_context. Manual PATCH only needed for credentials that change after installation.

For app developers: Write your documentation and context_prompt as if you're instructing an AI agent. Be explicit about which endpoints to call, what parameters to pass, and what the expected responses look like. The better your docs, the more effectively the AI agent can use your app.

Sending Inbox Messages

Notify users about job status, results, or important updates:

POST /installs/{install_id}/inbox [Install Secret]

// Request
{
  id: string,          // Idempotency key (unique per app+user)
  title: string,       // Max 200 chars
  text: string,        // Max 2000 chars
  url?: string,        // Link to results
  icon?: string        // Icon URL
}
// Response (201) — New message
{ success: true, message_id: string }
// Response (200) — Deduplicated
{ success: true, message_id: string, deduplicated: true }

curl -X POST https://cloud.officex.app/v1/installs/$INSTALL_ID/inbox \
  -H "Content-Type: application/json" \
  -H "x-officex-install-id: $INSTALL_ID" \
  -H "x-officex-install-secret: $INSTALL_SECRET" \
  -d '{
    "id": "job-12345-complete",
    "title": "Lead Enrichment Complete",
    "text": "Successfully enriched 50 leads. 3 could not be found.",
    "url": "https://myapp.com/results/12345"
  }'

Billing Patterns

Pattern 1: Free Apps

No reservations needed. Use inbox messages to communicate.

Pattern 2: One-Time Purchase

Reserve and settle immediately for discrete actions:

const reservation = await reserve({ amount: 0.5, job_id: `enrich-${leadId}` });
const result = await enrichLead(leadId);
await settle({ amount: 0.5, final: true });

Pattern 3: Usage-Based (Progressive Sip)

For long-running jobs, bill incrementally:

const reservation = await reserve({ amount: 10, job_id: `batch-${batchId}` });
for (const item of items) {
  await processItem(item);
  await settle({ amount: 0.1, final: false }); // sip per item
}
await settle({ amount: 0, final: true }); // finalize, refund unused

Pattern 4: Subscription-like

Use allowed_until for time-based access:

if (install.allowed_until !== -1 && Date.now()/1000 >= install.allowed_until) {
  return { error: "Please renew your subscription" };
}

Pattern 5: Internal Credits System (Recommended)

Decouple your app from OfficeX API by maintaining your own internal ledger:

1. Reserve + settle OfficeX credits in bulk
2. Mint equivalent internal credits in your DB
3. Your app logic consumes internal credits only — no OfficeX API calls during normal operation

OfficeX Credits (external)          Your App Credits (internal)
┌─────────────────────┐             ┌─────────────────────┐
│ User's OfficeX      │  reserve    │                     │
│ wallet              │────────────►│  (funds locked)     │
│                     │  settle     │  Internal ledger    │
│                     │────────────►│  += settled amount  │
│                     │             │  App consumes from  │
│                     │             │  internal ledger    │
└─────────────────────┘             └─────────────────────┘

async function settleAndMintCredits(reservationId, installId, installSecret, amount, final, userId) {
  const result = await fetch(`https://cloud.officex.app/v1/reservations/${reservationId}/settle`, {
    method: "POST",
    headers: { "Content-Type": "application/json", "x-officex-install-id": installId, "x-officex-install-secret": installSecret },
    body: JSON.stringify({ amount, final }),
  }).then(r => r.json());
  if (!result.success) throw new Error(result.error.message);
  await db.internalCredits.increment(userId, amount);
  return result;
}

// Reserve a block, settle immediately, user spends internal credits freely
const reservation = await reserve({ amount: 50, job_id: `session-${sessionId}` });
await settleAndMintCredits(reservation.reservation_id, installId, installSecret, 50, true, userId);
// Now user has 50 internal credits — no more OfficeX API calls needed

Benefits: decoupled from API availability, flexible internal pricing, auditability, batch funding, simpler error handling.

Frontend Integration (Iframe Embedding)

When users launch your app from OfficeX, it loads in an iframe with credentials as URL params:

https://your-app.com/officex?officex_customer_id={user_id}&officex_install_id={install_id}&officex_install_secret={install_secret}

Extracting Credentials

JavaScript/TypeScript:

const params = new URLSearchParams(window.location.search);
const customerId = params.get("officex_customer_id");
const installId = params.get("officex_install_id");
const installSecret = params.get("officex_install_secret");

if (!installId || !installSecret) {
  showError("Please access this app through the OfficeX app store");
  return;
}
sessionStorage.setItem("officex_install_id", installId);
sessionStorage.setItem("officex_install_secret", installSecret);

Python (Flask):

@app.route('/officex')
def officex_entry():
    install_id = request.args.get('officex_install_id')
    install_secret = request.args.get('officex_install_secret')
    if not install_id or not install_secret:
        return "Please access this app through OfficeX", 403
    session['officex_install_id'] = install_id
    session['officex_install_secret'] = install_secret
    return render_template('app.html')

Required: Allow OfficeX to Embed Your App

Your app must allow the OfficeX domain to embed it via iframe:

Content-Security-Policy: frame-ancestors 'self' https://officex.app https://*.officex.app

Next.js (next.config.js):

module.exports = {
  async headers() {
    return [{
      source: "/:path*",
      headers: [{ key: "Content-Security-Policy", value: "frame-ancestors 'self' https://officex.app https://*.officex.app" }],
    }];
  },
};

Express.js:

app.use((req, res, next) => {
  res.setHeader("Content-Security-Policy", "frame-ancestors 'self' https://officex.app https://*.officex.app");
  next();
});

Without this header: blank screen or console errors about "refused to frame."

Security:

• Never expose install_secret to users (use sessionStorage, not localStorage)
• Validate on backend for sensitive operations
• HTTPS required
• Handle missing params gracefully (users may bookmark deep links)

Webhook Authentication Flow (SSO)

The INSTALL webhook enables seamless single sign-on:

User clicks "Install" → OfficeX POSTs webhook → Your app creates/links user
→ Returns agent_context → User launches iframe → Lookup by install_id → Authenticated!

Implementing onInstall Authentication

Step 1: Handle webhook:

app.post("/webhooks/officex", async (req, res) => {
  const { event, payload, uuid } = req.body;
  if (event === "INSTALL") {
    const { install_id, install_secret, user_id, app_id, email } = payload;
    let user = await db.users.findOne({ officex_user_id: user_id });
    if (!user) {
      user = await db.users.create({ officex_user_id: user_id, officex_install_id: install_id, created_at: new Date() });
    } else {
      await db.users.update({ officex_user_id: user_id }, { officex_install_id: install_id });
    }
    // Return agent_context — credentials the AI agent needs to call your API
    res.json({ agent_context: { user_token: user.apiToken, base_url: "https://myapp.com/api/v1" } });
  } else {
    res.json({ received: true });
  }
});

Step 2: Look up user when iframe loads:

app.get("/officex", async (req, res) => {
  const installId = req.query.officex_install_id;
  const customerId = req.query.officex_customer_id;
  const user = await resolveUser(installId, customerId);
  req.session.user = user;
  req.session.officex = { install_id: installId, install_secret: req.query.officex_install_secret };
  res.redirect("/dashboard");
});

Handling Webhook Failures

Webhooks are fire-and-forget (no retries). Always have a fallback:

async function resolveUser(installId, customerId) {
  // Try install_id first (most specific)
  let user = await db.users.findOne({ officex_install_id: installId });
  if (user) return user;
  // Fall back to customer_id (they might have reinstalled)
  user = await db.users.findOne({ officex_user_id: customerId });
  if (user) {
    await db.users.update({ id: user.id }, { officex_install_id: installId });
    return user;
  }
  // No user found — create on-the-fly
  return await db.users.create({ officex_user_id: customerId, officex_install_id: installId, created_at: new Date() });
}

Fault Tolerance

Your app should treat OfficeX as an external payment layer, not a core dependency.

Principles:

1. Wrap all OfficeX API calls in try/catch with timeouts (3-5 seconds)
2. Your app should function if all OfficeX code was removed — OfficeX is how you get paid, not your runtime
3. Use the Internal Credits pattern (Pattern 5) for maximum resilience

Resilient billing wrapper:

async function safeReserve(installId, installSecret, amount, jobId) {
  try {
    const res = await fetch("https://cloud.officex.app/v1/reserve", {
      method: "POST",
      headers: { "Content-Type": "application/json", "x-officex-install-id": installId, "x-officex-install-secret": installSecret },
      body: JSON.stringify({ amount, job_id: jobId }),
      signal: AbortSignal.timeout(5000),
    }).then(r => r.json());
    if (!res.success) { console.error(`OfficeX reserve failed: ${res.error?.code}`, res.error); return res; }
    return res;
  } catch (err) {
    console.error("OfficeX API unreachable, queuing for retry:", err.message);
    await billingRetryQueue.enqueue({ installId, amount, jobId, attemptedAt: new Date() });
    return { success: false, error: { code: "OFFICEX_UNREACHABLE", message: err.message } };
  }
}

Error handling for reservations:

async function reserveWithRetry(installId, amount, jobId) {
  try {
    return await reserve(installId, amount, jobId);
  } catch (error) {
    if (error.code === "INSTALL_EXPIRED") {
      await sendInboxMessage(installId, { id: `renew-${jobId}`, title: "Authorization Expired", text: "Please renew your authorization to continue." });
    }
    if (error.code === "INSUFFICIENT_FUNDS") {
      await sendInboxMessage(installId, { id: `topup-${jobId}`, title: "Low Balance", text: `Need ${amount} credits. Please top up.` });
    }
    if (error.code === "RATE_LIMITED") {
      await sendInboxMessage(installId, { id: `ratelimit-${jobId}`, title: "Rate Limit Reached", text: "You've hit your usage limit for this period." });
    }
    throw error;
  }
}

Practical guidelines:

• Set aggressive timeouts (3-5 seconds) on all OfficeX API calls
• If reserve fails, consider letting user proceed and retrying billing later
• Webhooks are fire-and-forget — always have a fallback path (create users on-the-fly from iframe params)
• Log OfficeX errors instead of throwing unhandled exceptions

Complete Integration Example

1. Register app:

curl -X POST https://cloud.officex.app/v1/register-app \
  -H "Content-Type: application/json" \
  -H "x-officex-user-id: $OFFICEX_USER_ID" \
  -H "x-officex-master-key: $OFFICEX_API_KEY" \
  -d '{
    "name": "My Awesome App",
    "price_type": "PAY_PER_USE",
    "webhook_url": "https://myapp.com/webhooks/officex",
    "iframe_url": "https://myapp.com/officex",
    "documentation": "## API\n\nCall POST /api/enrich with {leadId} to enrich a lead.",
    "context_prompt": "This app enriches leads. Use the /api/enrich endpoint."
  }'

2. Handle webhook:

app.post("/webhooks/officex", async (req, res) => {
  const { event, payload } = req.body;
  if (event === "INSTALL") {
    const user = await db.users.upsert({
      officex_user_id: payload.user_id,
      officex_install_id: payload.install_id,
      officex_install_secret: payload.install_secret,
      email: payload.email,
    });
    return res.json({ agent_context: { api_key: user.apiKey, base_url: "https://myapp.com/api/v1" } });
  }
  res.json({ ok: true });
});

3. Handle iframe entry:

app.get("/officex", async (req, res) => {
  const user = await resolveUser(req.query.officex_install_id, req.query.officex_customer_id);
  req.session.user = user;
  req.session.officex = { install_id: req.query.officex_install_id, install_secret: req.query.officex_install_secret };
  res.redirect("/dashboard");
});

4. Bill from your app:

app.post("/api/enrich-lead", async (req, res) => {
  const { install_id, install_secret } = req.session.officex;
  const { leadId } = req.body;

  const reservation = await safeReserve(install_id, install_secret, 5, `enrich-${leadId}-${Date.now()}`);
  if (!reservation.success) return res.status(400).json({ error: reservation.error });

  const enrichedData = await enrichLead(leadId);

  await fetch(`https://cloud.officex.app/v1/reservations/${reservation.reservation_id}/settle`, {
    method: "POST",
    headers: { "Content-Type": "application/json", "x-officex-install-id": install_id, "x-officex-install-secret": install_secret },
    body: JSON.stringify({ amount: 5, final: true }),
  });

  res.json({ success: true, data: enrichedData });
});

FAQ

How do I test without real money? Redeem a voucher code to add free credits to your wallet: POST /vouchers/{code}/redeem.

Can my app have multiple pricing tiers? Yes. Your app logic decides how many credits to reserve per action.

What happens if my webhook is down? Webhooks are fire-and-forget. Handle gracefully by polling installation status or creating users on-the-fly from iframe params.

Can I transfer credits between apps I own? No. Credits only flow through reservation/settlement. Each app wallet is independent.
