PARAMS="?apiKey=${API_KEY}&currencyCode=eth&walletAddress=<WALLET>&baseCurrencyAmount=100"

# Sign URL (required for production)
SIGNATURE=$(echo -n "${PARAMS}" | openssl dgst -sha256 -hmac "${SECRET_KEY}" -binary | base64 | tr '+/' '-_' | tr -d '=')

WIDGET_URL="${BASE_URL}${PARAMS}&signature=${SIGNATURE}"
echo "Widget URL: $WIDGET_URL"
```

## Create Transaction (Server-Side)

```bash
API_KEY="${MOONPAY_API_KEY}"

  -H "Content-Type: application/json" \
  -d '{
    "baseCurrencyCode": "usd",

    quoteCurrencyAmount: .quoteCurrencyAmount,
    walletAddress: .walletAddress
  }'
```

## Webhook Events

```bash

  "data": {
    "id": "tx-123",
    "status": "completed",
    "cryptoTransactionId": "0x...",
    "quoteCurrencyAmount": 0.05,
    "walletAddress": "0x..."
  }
}
```

## Verify Webhook Signature

```bash
verify_webhook() {
  local payload="$1"
  local signature="$2"
  
  local expected=$(echo -n "$payload" | openssl dgst -sha256 -hmac "$MOONPAY_SECRET_KEY" -binary | base64)
  
  [[ "$signature" == "$expected" ]]
}
```

## Widget Customization

```bash
# Widget parameters
PARAMS="?apiKey=${API_KEY}"
PARAMS+="&currencyCode=eth"
PARAMS+="&walletAddress=<WALLET>"
PARAMS+="&baseCurrencyAmount=100"
PARAMS+="&baseCurrencyCode=usd"
PARAMS+="&lockAmount=true"           # Lock amount
PARAMS+="&colorCode=%23FF6B00"       # Custom color
PARAMS+="&language=en"               # Language
PARAMS+="&showWalletAddressForm=false"  # Hide wallet input
```

## Safety Rules

1. **ALWAYS** sign widget URLs in production
2. **NEVER** expose secret key client-side
3. **VERIFY** webhook signatures
4. **CHECK** transaction status before fulfilling
