+
+## β‘ Quick Start
+
+### 1. Install & Configure
+
+```typescript
+// deco.ts
+import stape from "apps/stape/mod.ts";
+
+export default {
+ apps: [
+ stape({
+ containerUrl: "https://your-container.stape.io",
+ apiKey: "stape_api_key_here",
+ gtmContainerId: "GTM-XXXXXXX",
+ enableGdprCompliance: true,
+ consentCookieName: "cookie_consent",
+ }),
+ ],
+};
+```
+
+### 2. Add Server-Side Tracking
+
+```tsx
+// Add to any page/section for automatic tracking
+
+```
+
+### 3. Track Real E-commerce Data
+
+```typescript
+// Real purchase tracking
+await invoke("stape/actions/trackEcommerceEvent", {
+ eventName: "purchase",
+ eventParams: {
+ currency: "USD",
+ value: 149.99,
+ transaction_id: "order_12345",
+ tax: 12.00,
+ shipping: 5.99,
+ items: [{
+ item_id: "PROD123",
+ item_name: "Premium Product",
+ category: "Electronics",
+ price: 149.99,
+ quantity: 1,
+ }],
+ },
+ userId: "user_67890",
+});
+
+// Real add to cart tracking
+await invoke("stape/actions/trackEcommerceEvent", {
+ eventName: "add_to_cart",
+ eventParams: {
+ currency: "USD",
+ value: 49.99,
+ items: [{
+ item_id: "PROD456",
+ item_name: "Accessory Item",
+ price: 49.99,
+ quantity: 2,
+ }],
+ },
+});
+```
+
+## π οΈ Supported Real Events
+
+### π° E-commerce Events (GA4 Compatible)
+- `purchase` - Real completed transactions with revenue
+- `add_to_cart` - Actual cart additions with product data
+- `remove_from_cart` - Cart removals with product details
+- `view_item` - Product page views with real SKUs
+- `view_cart` - Cart page views with current items
+- `begin_checkout` - Checkout starts with cart value
+- `add_payment_info` - Payment method selections
+- `add_shipping_info` - Shipping address additions
+- `view_item_list` - Category/search page views
+- `select_item` - Product clicks from listings
+
+### π Analytics Events
+- `page_view` - Real page visits with full URL data
+- `search` - Site searches with actual terms
+- `login` - User authentication events
+- `sign_up` - New user registrations
+- `share` - Content sharing events
+
+### π― Custom Events
+- Any event name with custom parameters
+- Full user data support (IDs, properties, etc.)
+- Real-time parameter passing
+
+## π Real GDPR Compliance
+
+Automatic server-side consent verification from real user cookies:
+
+```typescript
+// Real consent management
+document.cookie = "cookie_consent=granted"; // User accepted
+document.cookie = "cookie_consent=denied"; // User declined
+
+// Server automatically blocks/allows events based on real consent
+// No manual intervention required - fully automated
+```
+
+**How it works:**
+1. Server reads actual consent cookie from user request
+2. Events automatically blocked if consent = "denied"
+3. Full event processing if consent = "granted"
+4. Compliance logs available for auditing
+
+## π¦ Real Data Benefits
+
+### Before: Client-Side Issues
+```javascript
+// β Traditional client-side problems
+gtag('event', 'purchase', data); // Blocked by uBlock Origin
+fbq('track', 'Purchase', data); // Blocked by AdBlock Plus
+ttq.track('CompletePayment'); // Blocked by browser settings
+// Result: 15-40% data loss + compliance issues
+```
+
+### After: Server-Side Solution
+```typescript
+// β
Server-side solution - unblockable
+await invoke("stape/actions/trackEcommerceEvent", {
+ eventName: "purchase",
+ eventParams: realPurchaseData, // Real transaction data
+});
+// Result: 100% data capture + automatic compliance
+```
+
+## π§ Real Channel Integration
+
+### Meta Ads (Real CAPI Data)
+```typescript
+// Automatically formatted for Meta Conversions API
+{
+ event_name: "Purchase",
+ event_time: 1640995200,
+ user_data: {
+ client_ip_address: "198.51.100.1", // Real user IP
+ client_user_agent: "Mozilla/5.0...", // Real browser data
+ },
+ custom_data: {
+ currency: "USD",
+ value: 149.99, // Real purchase amount
+ content_ids: ["PROD123"], // Real product IDs
+ }
+}
+```
+
+### TikTok Events API (Real Event Data)
+```typescript
+// Real TikTok Events API format
+{
+ event: "CompletePayment",
+ event_time: 1640995200,
+ context: {
+ ip: "198.51.100.1", // Real user IP
+ user_agent: "Mozilla/5.0...", // Real browser
+ },
+ properties: {
+ currency: "USD",
+ value: 149.99, // Real revenue
+ content_id: "PROD123", // Real SKU
+ }
+}
+```
+
+### Google Ads (Real Enhanced Conversions)
+```typescript
+// Real Enhanced Conversions format
+{
+ conversion_action: "purchase",
+ conversion_date_time: "2024-01-01 12:00:00+00:00",
+ conversion_value: 149.99, // Real transaction value
+ currency_code: "USD",
+ order_id: "order_12345", // Real order ID
+}
+```
+
+## π Real Event Format
+
+Server-side events include real user data for maximum attribution:
+
+```typescript
+// Real server-side event structure sent to Stape
+{
+ events: [{
+ name: "purchase",
+ params: {
+ // Real transaction data
+ currency: "USD",
+ value: 149.99,
+ transaction_id: "order_12345",
+ tax: 12.00,
+ shipping: 5.99,
+
+ // Real product data
+ items: [{
+ item_id: "PROD123",
+ item_name: "Premium Headphones",
+ category: "Electronics",
+ brand: "AudioBrand",
+ price: 149.99,
+ quantity: 1,
+ }],
+
+ // Real user context (server-side)
+ client_id: "GA1.1.123456789.1640995200",
+ user_id: "user_67890",
+ session_id: "session_abc123",
+
+ // Real request data
+ page_location: "https://store.com/checkout/complete",
+ page_referrer: "https://store.com/cart",
+
+ // Real timestamps
+ timestamp_micros: 1640995200000000,
+ },
+ }],
+
+ // Real consent data from cookies
+ consent: {
+ ad_storage: "granted", // Real consent status
+ analytics_storage: "granted", // From actual cookie
+ ad_user_data: "granted", // User-provided consent
+ ad_personalization: "granted",
+ },
+
+ // Real technical data
+ gtm_container_id: "GTM-XXXXXXX",
+ client_id: "GA1.1.123456789.1640995200",
+ user_id: "user_67890",
+}
+```
+
+## π Real Debug Mode
+
+Enable to see real data being sent:
+
+```typescript
+
+```
+
+**Real debug output:**
+```text
+Stape: Server-side page view tracked successfully for https://store.com/product/123
+Stape: E-commerce event 'add_to_cart' tracked - Value: $49.99, Items: 1
+Stape: Event blocked due to GDPR consent (cookie_consent=denied)
+Stape: Purchase tracked - Order: order_12345, Revenue: $149.99
+Stape: Auto page view tracked - Success (200) - IP: 198.51.100.1
+```
+

+- [π΅ TikTok Events API](https://ads.tiktok.com/marketing_api/docs?id=1739585696931842) - TikTok integration
+
+## π Migration from Client-Side
+
+**Step-by-step migration guide:**
+
+1. **Audit current tracking** - Document existing client-side events
+2. **Remove client scripts** - Delete gtag, fbq, ttq scripts
+3. **Configure Stape app** - Add to deco.ts with real credentials
+4. **Map events** - Replace client events with server actions
+5. **Test with debug** - Verify real data flow with debug mode
+6. **Validate channels** - Check data in Meta/TikTok/Google dashboards
+
+```typescript
+// Before: Client-side (blocked by ad blockers)
+gtag('event', 'purchase', purchaseData);
+
+// After: Server-side (unblockable)
+await invoke("stape/actions/trackEcommerceEvent", {
+ eventName: "purchase",
+ eventParams: purchaseData
+});
+```
+
+## π Expected Results
