Export to PDF On-Premises REST API usage

The Export to PDF On-Premises converter provides the ability to convert an HTML document to a PDF file via Restful API.

The API is available on http://localhost:[port] (by default the port is 8080).

Note

The REST API documentation is available at http://localhost:[port]/docs.
Alternatively, you can check the specifications in our public resources https://pdf-converter.cke-cs.com/docs.

If you have the authorization for the API enabled, you should provide an authorization token. More instructions you can find in the authorization section.

Using additional HTTP headers

If fetching some resources (e.g. images) used in a generated PDF requires passing an additional authorization factor in the form of additional HTTP headers:

It can be defined on the application startup by setting EXTRA_HTTP_HEADERS environmental variable where the value is a stringified JSON object with required headers.
It can be defined in a request sent to the PDF Converter API in options:

const data = {
   html: '<p>I am a teapot</p><img src="https://secured-example-website.com/image.jpg">',
   css: 'p { color: red; }',
   options: {
      extra_http_headers: {
        authorization: 'Bearer RDp0NqyePooNWFIWvHtbKrKKHLXfmLfZcv3PRpCyJI90uwi3pKvumKl2vymCxoGFw6Vx'
      }
   }
};

axios.post( 'https://pdf-converter.cke-cs.com/v1/convert', data, config )
   .then( response => {
      fs.writeFileSync('./file.pdf', response.data, 'binary')
   } ).catch( error => {
      console.log( error );
   } );

Headers defined in the application config and from the request are merged. If the same header is defined in both places, a header value from PDF options is prioritized over the value from the application config.
