Options

There are many options available to wkhtmltopdf. All of the command line options are supported as documented on the page linked to above. The options are camelCased instead-of-dashed as in the command line tool. Note that options that do not have values, must be specified as a boolean, e.g. debugJavascript: true

{
    "htmlBase64" : "PGJvZHk+SGVsbG8gd29ybGQ8L2JvZHk+",
    "options":
    {
        "pageSize": "letter"
    }
