## Shield Installation Guide
Shield is a client-side drop-in replacement for Stripe.js that enriches your PaymentIntents with device-based risk signals for Stripe Radar. No backend changes are required.
### Step 1: Replace loadStripe() with Shield
This is the only required code change. Replace your existing Stripe.js initialization:
**Before (Stripe.js):**
```javascript
const stripe = await loadStripe('pk_live_your_publishable_key');
```
**After (Shield):**
```javascript
// Load Shield SDK
const script = document.createElement('script');
script.src = 'https://cdn.gocanonical.com/shield/latest/shield.js';
script.onload = async () => {
try {
const Shield = window.Shield;
if (typeof Shield?.Shield === 'function') {
// Shield.Shield replaces loadStripe
const stripe = await Shield.Shield('pk_live_your_publishable_key');
// Use "stripe" exactly as you would use Stripe.js
// Continue your existing payment code here...
}
} catch (error) {
console.error('Error initializing Shield:', error);
}
};
script.onerror = () => console.error('Failed to load Shield SDK');
document.head.appendChild(script);
```
### Complete Example
```html
Checkout with Shield
```
**Important:** Replace `pk_live_your_publishable_key` with your actual Stripe publishable key. Make sure the PK you use is from the same Stripe account you install the Shield App from. The Shield SDK initializes asynchronously, so ensure your payment logic runs after the script loads.
### Content Security Policy (CSP) Configuration
If your app uses a strict CSP, add these domains:
1. **Allow Shield SDK script:**
```
script-src ... https://cdn.gocanonical.com;
```
2. **Allow Stripe.js:**
```
script-src ... https://js.stripe.com;
```
3. **Allow Shield + Stripe network requests:**
```
connect-src ... https://api.gocanonical.com https://cdn.gocanonical.com https://api.stripe.com;
```
4. **Allow Stripe Elements and 3DS iframes:**
```
frame-src ... https://js.stripe.com https://hooks.stripe.com;
```
**Reference CSP (merge with your existing policy):**
```
Content-Security-Policy:
default-src 'self';
script-src 'self' 'unsafe-inline' 'unsafe-eval' data:
https://cdn.gocanonical.com
https://js.stripe.com;
connect-src 'self'
https://api.gocanonical.com
https://cdn.gocanonical.com
https://api.stripe.com;
frame-src
https://js.stripe.com
https://hooks.stripe.com;
img-src 'self' data:;
style-src 'self' 'unsafe-inline';
font-src 'self' data:;
```
