Export PDF

Similar to the Export HTML function, you can also export a design in PDF format. This would upload the generated PDF to your connected File Storage and send the link to the callback function.

Note: Unlike HTML or plain text, PDF is not generated on the client. This function uses our cloud API to generate the PDF.

unlayer.exportPdf(function (data) {
  var json = data.design; // design json
  var pdfUrl = data.url; // pdf url

  // Do something with the PDF url
});

Callback Parameters​

The exportPdf callback returns the following parameters.

NameDescription
designThis is the JSON of the design
urlThis is the URL of the generated PDF

Export Options​

You can also pass certain options to this function as a second parameter.

Merge Tags​

If you want the Merge Tags in your design to be replaced by different values, you can pass the mergeTags object to export options.

unlayer.exportPdf(
  function (data) {
    var json = data.design; // design json
    var pdfUrl = data.url; // pdf url
  },
  {
    mergeTags: {
      first_name: 'John',
      last_name: 'Doe',
    },
  },
);

Cloud API​

If you want to generate the PDF on the server-side, you can use our Cloud API.

const fetch = require('node-fetch');

let url = 'https://api.unlayer.com/v2/export/pdf';

let options = {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    Authorization: 'Basic BASE64-ENCODED-API-KEY',
  },
  body: JSON.stringify({
    displayMode: 'email',
    design: {}, // json of your design
    mergeTags: { first_name: 'John', last_name: 'Doe' },
  }),
};

fetch(url, options)
  .then((res) => res.json())
  .then((json) => console.log(json))
  .catch((err) => console.error('error:' + err));
