![]() ![]() pdf".format(invoice_id), "wb") as f:īut there are still limitations of what kind of data and how much you can pass just using URLs, so you would need to modify the script to use POST requests instead if you were sending a lot of dynamic data. In the example below, I've added INVOICE NO. (You'll need a Google Account).Īdd placeholders where you need dynamic information. Use one of the built in Google Document templates, search online for one that matches your needs, or build your own over at. We'll be writing a few lines of Google App Script code, and a few lines of Python code. In reality, you'd need to do the same for a lot of the other fields, but we'll start with a simple example for demonstration reasons. In this tutorial, we'll walk through creating an API that generates these invoices and lets you programmatically insert the invoice number from an external Python script. I started off with an invoice template that I found online. You'll get a free API, and you'll be able to use Google Docs as your templating tool, which is quite powerful and has many pre-existing templates for things like invoices, letters, and CVs. While one of the options above may work for you, if you don't like any of them, you can also hack together a document generation API based on Google Drive. Usually, you also have to pay to use the service. Although you get a drag-and-drop interface, it's quite clunky and difficult to make your template look as you want. Option 3 requires you to build the template first using an online service's web interface. Option 2 can often work better, but you still have to build the Jinja HTML boilerplate, and sometimes the HTML to PDF conversion doesn't come out quite as you expected. You have to draw anything you need element by element, using code, and even once you've got a template looking the way you want it, it's difficult to maintain. see )įor Option 1, generating PDFs directly from inside Python can make formatting very difficult. Use an HTML templating library like Jinja2 and convert from HTML to PDF (e.g. ![]() Use a PDF library like reportlab to generate PDF files directly (e.g.Whether you're creating invoices, letters, reports, or any other documents that contain a lot of formatting repetition but only a little bit of dynamic content, adding some automation can save you many hours. Often, it's useful to create PDF files from your Python scripts. ![]()
