Send custom HTTP headers in Node with Got

In this guide, we'll walk you through the process of sending custom HTTP headers when requesting an URL to be converted to PDF using PDFShift's API.

This can be useful to pass custom parameters to your server. It can help for instance to identify from where is coming the request, and add some extra layer of security.

const got = require('got');
const fs = require('fs');

// You can get an API key at https://pdfshift.io
api_key = 'sk_xxxxxxxxxxxx'

params = {
    source: 'https://www.example.com',
    http_headers: {
        'x-custom-header': 'custom-value',
        Authorization: 'Bearer {token}'  // This allows you to authenticate PDFShift to your service in a custom way
    }
}

const response = await got.post('https://api.pdfshift.io/v3/convert/pdf', {
    auth: 'api:' + apiKey,
    json: params,
    responseType: 'buffer'
});

// Write the buffer as result.pdf
fs.writeFileSync('result.pdf', await response.buffer());

console.log('The PDF document was generated and saved to result.pdf');

This allows you to set specific HTTP headers that will be send along with the request PDFShift will make to your server. It can be helpful to authenticate the request that your backend can check against before converting it to PDF.

For further details on the http_headers property and its usage, please refer to our dedicated documentation.
