# HTML and script tag
> Install Biqli on a website without a package manager.
Use the global script when your site uses plain HTML, a site builder, or a framework that can add one script to every tracked page.
## Add the script
Place this once inside ``:
```html theme={null}
```
The script creates `window.Biqli`, initializes one managed SDK instance, captures `bq_id`, and watches single-page navigation.
## Supported attributes
| Attribute | Meaning |
| :----------------------- | :---------------------------------------------- |
| `data-publishable-key` | Required browser key beginning with `biqli_pk_` |
| `data-api-host` | Optional API host or fixed reverse-proxy base |
| `data-attribution-model` | `first-click` or `last-click` |
| `data-outbound-domains` | Comma-separated exact or wildcard hostnames |
| `data-query-parameters` | Comma-separated click-ID query parameters |
| `data-manual-start` | Use `true` to delay lifecycle startup |
| `data-consent` | Use `false` when consent is not yet granted |
## Track a lead
```html theme={null}
```
## Track a sale
```js theme={null}
await window.Biqli.trackSale({
customerExternalId: 'customer_1842',
amount: 4999,
currency: 'usd',
paymentProcessor: 'custom',
invoiceId: 'order_9381',
});
```
## Useful global methods
```js theme={null}
Biqli.getClickId();
Biqli.setClickId('known_click_id');
Biqli.clearClickId();
Biqli.setConsent(true);
Biqli.decorateUrl('https://checkout.example.com/cart');
Biqli.teardown();
```
Do not add the script more than once. The verifier reports duplicate installations because multiple SDK instances can create competing lifecycle handlers.
