+
+const tabs = [
+  { id: 'tab1', label: 'Label', icon: <Icon /> },
+  { id: 'tab2', label: 'Label', icon: <Icon /> },
+];
+
+// Tab Navigation UI
+<nav className="-mb-px flex space-x-8">
+  {tabs.map((tab) => (
+    <button
+      onClick={() => setActiveTab(tab.id)}
+      className={activeTab === tab.id ? 'active-styles' : 'inactive-styles'}
+    >
+      {tab.icon}
+      {tab.label}
+    </button>
+  ))}
+</nav>
+
+// Tab Content
+{activeTab === 'tab1' && <TabContent1 />}
+{activeTab === 'tab2' && <TabContent2 />}
+```

+
+## Backend Integration Requirements
+
+### Invitations Tab (Team Management)
+**Missing Endpoint:** `GET /v1/account/team/invitations/`
+**Response:**
+```json
+{
+  "results": [
+    {
+      "id": 1,
+      "email": "user@example.com",
+      "status": "pending",
+      "sent_at": "2025-12-01T10:00:00Z",
+      "expires_at": "2025-12-08T10:00:00Z"
+    }
+  ]
+}
+```
+
+**Actions Needed:**
+- `POST /v1/account/team/invitations/resend/` - Resend invitation
+- `DELETE /v1/account/team/invitations/:id/` - Cancel invitation
+
+### API Usage Tab (Usage Analytics)
+**Missing Endpoint:** `GET /v1/account/usage/api-stats/`
+**Response:**
+```json
+{
+  "total_calls": 15234,
+  "avg_calls_per_day": 507,
+  "success_rate": 98.5,
+  "endpoints": [
+    {
+      "path": "/api/v1/content/generate",
+      "calls": 12345,
+      "description": "Content generation"
+    }
+  ]
+}
+```
+
+### Cost Breakdown Tab (Usage Analytics)
+Currently uses calculated data from credit usage. Could be enhanced with:
+**Optional Endpoint:** `GET /v1/account/usage/cost-breakdown/`
+**Response:**
+```json
+{
+  "total_cost_usd": 123.45,
+  "avg_cost_per_day": 4.12,
+  "cost_per_credit": 0.01,
+  "by_operation": [
+    {
+      "operation_type": "content_generation",
+      "credits": 5000,
+      "cost_usd": 50.00
+    }
+  ]
+}
+```

+
+## ⚠️ CORRECT DATA STRUCTURE FOR PAGES
+
+### AccountBillingPage.tsx
+**Should use:**
+- `getCreditBalance()` → `/v1/billing/credits/balance/balance/`
+- `getInvoices()` → `/v1/billing/invoices/`
+- `getPayments()` → `/v1/billing/payments/`
+
+**Data fields to use:**
+```typescript
+creditBalance.credits  // NOT balance
+creditBalance.plan_credits_per_month  // NOT monthly_credits
+creditBalance.credits_used_this_month  // NEW field
+```
+
+### AccountSettingsPage.tsx
+**Should use:**
+- `getAccountSettings()` → `/v1/account/settings/`
+- `updateAccountSettings(data)` → `PATCH /v1/account/settings/`
+
+### TeamManagementPage.tsx
+**Should use:**
+- `getTeamMembers()` → `/v1/account/team/`
+- `inviteTeamMember(email)` → `POST /v1/account/team/`
+- `removeTeamMember(id)` → `DELETE /v1/account/team/{id}/`
+
+### UsageAnalyticsPage.tsx
+**Should use:**
+- `getUsageAnalytics(days)` → `/v1/account/usage/analytics/?days=30`
+
+**Data fields to use:**
+```typescript
+analytics.current_balance
+analytics.usage_by_type  // Array with transaction_type, total, count
+analytics.daily_usage    // Array with date, usage, purchases, net
+analytics.total_usage
+analytics.total_purchases
+```
+
+### PurchaseCreditsPage.tsx
+**Should use:**
+- `getCreditPackages()` → `/v1/billing/credit-packages/`
+- `getPaymentMethods()` → `/v1/billing/payment-methods/`
+- `purchaseCreditPackage(data)` → `POST /v1/billing/credit-packages/{id}/purchase/`
+
+## 🔑 KEY POINTS
+
+1. **Account Relationship:** All endpoints automatically filter by the logged-in user's account. The backend middleware sets `request.account` from the JWT token.
+
+2. **Unified Response Format:** All endpoints return data in the format:
+   ```json
+   {
+     "success": true,
+     "data": { ... }
+   }
+   ```
+   The `fetchAPI` function in `services/api.ts` automatically extracts the `data` field.
+
+3. **Field Names:** Backend uses specific field names that MUST match in frontend:
+   - `credits` (NOT `balance`)
+   - `plan_credits_per_month` (NOT `monthly_credits`)
+   - `credits_used_this_month` (NEW)
+   - `credits_remaining` (NEW)
+
+4. **No Fake Data:** Pages must load real data from these endpoints. NO placeholder data.
+
+5. **Error Handling:** If endpoint returns 404, the backend route is not registered. Check `backend/igny8_core/urls.py` and restart backend container.
+

+
+- [ ] Update `billing.api.ts` to use correct endpoints
+- [ ] Update type interfaces to match backend response
+- [ ] Fix AccountBillingPage to use `credits`, `plan_credits_per_month`, `credits_used_this_month`
+- [ ] Fix UsageAnalyticsPage to use `usage_by_type`, `daily_usage` structure
+- [ ] Fix PurchaseCreditsPage to call correct payment-methods endpoint
+- [ ] Fix TeamManagementPage to handle optional `date_joined` field
+- [ ] Fix AccountSettingsPage to load from `/v1/account/settings/`
+- [ ] Remove all placeholder/fake data
+- [ ] Test all pages with real backend data
