URL-Based Generation

Generate a PDF from an existing web page by providing its URL:

{
    "url": "https://www.pdfbroker.io",
    "weasyPrintToPdfArguments": {
        "pdf-variant": "pdf/ua-1"
    }
}

Inline Markup Generation

Generate a PDF from inline HTML by providing Base64-encoded markup. Resources like images can be included separately:

{
    "url": null,
    "htmlBase64String": "PCFET0NUWVBFIGh0bWw...",
    "weasyPrintToPdfArguments": {
        "pdf-variant": "pdf/ua-1"
    },
    "resources": {
        "pdfbroker_logo.svg": "PHN2ZyBpZD0iTGFnZXJfMS..."
    }
}

Resources

Images and other files referenced in your HTML template can be provided as Base64-encoded values in the resources object. The key should match the filename used in the template.
