## HTML Templates

<Warning>
  During conversion, the API performs variable substitution and built-in helper evaluation using your [templateData](#html-templates), but does not execute any arbitrary JavaScript within the template itself. After the template is rendered into HTML, a headless browser processes the page and executes any in-page JavaScript triggered on load. External or dynamically loaded JavaScript libraries may run if accessible, but execution is not guaranteed in all environments. This separation ensures secure, predictable template handling and accurate rendering of interactive web content.
</Warning>

Use the dashboard to manage your HTML to [PDF Templates](https://app.pdf.co/html-templates-tool).

Templates use `{{Mustache}}` and Handlebars templating syntax. You just need to insert macros surrounded by double brackets like `{{` and `}}`.

* Find out more about [Mustache](https://mustache.github.io/mustache.5.html).

* Find out more about [Handlebars](https://handlebarsjs.com/guide/).

Some Examples of macro inside html template:

* `{{variable1}}` will be replaced with `test` if you set `templateData` to `{ "variable1": "test" }`
* `{{object1.variable1}}` will be replaced with `test` if you set `templateData` to `{ "object1": { "variable1": "test" } }`
* Simple conditions are also supported. For example: `{{#if paid}} invoice was paid {{/if}}` will show invoice was paid when `templateData` is set to `{ "paid": true }`.

### Handlebars

Handlebars extends Mustache with powerful features like conditional logic, loops, and custom helper functions. You can use Handlebars helpers like `#if`, `#unless`, `#each` (see [https://handlebarsjs.com/guide/builtin-helpers.html](https://handlebarsjs.com/guide/builtin-helpers.html)) but you can also define your own helper functions for complex calculations and data manipulation.

#### Key Handlebars Features:

* **Variable substitution**: `{{variable}}` syntax for inserting data
* **Conditional logic**: `{{#if}}` and `{{#unless}}` blocks for conditional rendering
* **Loops**: `{{#each}}` for iterating over arrays and objects
* **Nested objects**: Accessing properties with dot notation like `{{company.name}}`
* **Built-in helpers**: Using Handlebars' built-in functionality for common operations

### Sample JSON input

```json theme={null}
"templateData": "{ 'paid': true, 'invoice_id': '0002', 'total': '$999.99' }"
```

<Note>If you use `JSON` as input then make sure to escape it first (with `JSON.stringify(dataObject)` in JS). Escaping is when every `"` is replaced with `\"`. Example with `"` be escaped as `\"` then: `"templateData": "{ \"paid\": true, \"invoice_id\": \"0002\", \"total\": \"$999.99\" }"`.</Note>

### Sample CSV input

```csv theme={null}
"templateData": "paid,invoice_id,total
true,0002,$999.99"
```

## Header & Footer

The `header` and `footer` parameters can contain valid HTML markup with the following classes used to inject printing values into them:

* `date`: formatted print date
* `title`: document title
* `url`: document location
* `pageNumber`: current page number
* `totalPages`: total pages in the document

img: tag is supported in both the header and footer parameter, provided that the `src` attribute is specified as a `base64-encoded` string.

For example, the following markup will generate `Page N of NN` page numbering:

```html theme={null}
<span style='font-size:10px'>Page <span class='pageNumber'></span> of <span class='totalPages'></span>.</span>
```

### Sample Header & Footer

An example with an advanced `header` and `footer`. Note that the top and bottom page margins are important because page content may overlap the footer or header.

<Note>
  **Inconsistent URL Encoding in cURL Output:** When using cURL to make API requests, the output JSON may show URL characters encoded as Unicode escape sequences. For example, the ampersand character (`&`) may appear as `\u0026` in the cURL output. This is normal JSON encoding behavior and does not affect the validity of the URL. The URL will function correctly when used, as JSON parsers automatically decode these escape sequences. If you're parsing the response programmatically, your JSON parser will handle this conversion automatically.
