Conversión CFDI a PDF

Converting CFDI to PDF

redocmx

The redocmx module is a Python client for interacting with the redoc.mx REST API to convert CFDIs (Comprobante Fiscal Digital por Internet) to PDFs.

This client simplifies the process of sending XML data and retrieving the converted PDF, along with transaction details and metadata.

This package is synchronous.

Installation

To install the module, run:

pip install redocmx

Usage

First, import the module and create an instance of the Redoc client.

You can optionally pass your API key as an argument, or the client will attempt to load it from the REDOC_API_KEY environment variable.

from redocmx import RedocmxClient

redoc =  RedocmxClient('your_api_key_here')

Converting CFDI to PDF

The redocmx provides two options for loading CFDI data: from a file or directly from a string.

Option 1: Load XML from the File System

cfdi = redoc.cfdi.from_file('./path/to/your/file.xml')

Option 2: Use an XML Content String

cfdi = redoc.cfdi.from_string('<xml_content_string_here>');

Generating the PDF

To convert the loaded CFDI to a PDF:

try:
	pdf = cfdi.to_pdf()
	
	with open('./nomina.pdf', 'wb') as pdf_file:
		pdf_file.write(pdf.to_buffer())

	print(f"Transaction ID: {pdf.get_transaction_id()}")
	print(f"Total Pages: {pdf.get_total_pages()}")
	print(f"Total Time: {pdf.get_total_time_ms()} ms")
	print(f"Metadata: {pdf.get_metadata()}")
		
except:
	print("An error occurred during the conversion")

{
    "style_pdf": "John"
}

Pdf

The pdf object is an instance of Pdf, created from cfdi.to_pdf(options).

Method	Description
pdf.to_buffer()	Returns: Buffer The PDF document as a buffer, ready for storage in the file system or to be sent back in an HTTP request.
