    "walletAddress": "0x..."
  }
}
```

## Verify Webhook

```bash
verify_webhook() {
  local payload="$1"
  local signature="$2"
  
  local expected=$(echo -n "$payload" | openssl dgst -sha256 -hmac "$TRANSAK_SECRET" | cut -d' ' -f2)
  
  [[ "$signature" == "$expected" ]]
}
```

## Widget Customization

```bash
# Additional widget parameters
WIDGET_URL+="&themeColor=0066FF"           # Custom color
WIDGET_URL+="&hideMenu=true"               # Hide menu
WIDGET_URL+="&disableWalletAddressForm=true"  # Lock wallet

## Safety Rules

1. **VERIFY** webhook signatures
2. **NEVER** expose API keys client-side
3. **CHECK** order status before fulfilling
4. **VALIDATE** wallet addresses

| `INVALID_API_KEY` | Bad API key | Check credentials |
