// Data to fill the template
const templateData = "./invoice_data.json";
// Destination PDF file name
const DestinationFile = "./result.pdf";

/* 
Please follow below steps to create your own HTML Template and get "templateId". 
1. Add new html template in app.pdf.co/templates/html
2. Copy paste your html template code into this new template. Sample HTML templates can be found at "https://github.com/bytescout/pdf-co-api-samples/tree/master/PDF%20from%20HTML%20template/TEMPLATES-SAMPLES"
3. Save this new template
4. Copy it’s ID to clipboard
5. Now set ID of the template into “templateId” parameter
