How to send a PDF file to a WhatsApp group in Python

This article shows you how to send a document (e.g. a PDF file, an MP4 file, a WAV file, etc.) to a WhatsApp group in Python.

To send a PDF document to a WhatsApp group in Python, do this:

1. First, learn how to send a simple text message on the official site.
2. With the above knowledge, you can now download our sample code.
3. Locate the file python/send-pdf-group.py.

   	#!/usr/bin/env python
   	import base64
   	import requests
   	# TODO: When you have your own Client ID and secret, put down their values here:
   	instanceId = "YOUR_GATEWAY_INSTANCE_ID_HERE"
   	clientId = "YOUR_OWN_ID_HERE"
   	clientSecret = "YOUR_OWN_SECRET_HERE"
   	# TODO: Customize the following 3 lines
   	group = 'YOUR UNIQUE GROUP NAME HERE' # TODO Specify your unique group name here
   	fullpath_to_document = "../assets/subwaymap.pdf"
   	fn = "anyname.pdf"
   	caption = "You will find it useful" # caption is optional; can be None
   	# Encode the document in base64 format
   	doc_base64 = None
   	with open(fullpath_to_document, 'rb') as doc:
   	doc_base64 = base64.b64encode(doc.read())
   	headers = {
   	'X-WM-CLIENT-ID': clientId,
   	'X-WM-CLIENT-SECRET': clientSecret
   	}
   	jsonBody = {
   	'group_name ': group,
   	'document': doc_base64,
   	'filename': fn,
   	'caption': caption
   	}
   	r = requests.post("http://api.whatsmate.net/v3/whatsapp/group/document/message/%s" % instanceId,
   	headers=headers,
   	json=jsonBody)
   	print("Status code: " + str(r.status_code))
   	print("RESPONSE : " + str(r.content))

4. Study the Python source code and customize the TODO/FIXME lines.
   • Among other things, you must name your group creatively. Otherwise, the group may not receive the message.
5. Change to the directory containing the script: cd python
6. Run the Python script to send yourself the first PDF file: ./send-pdf-group.py

Happy coding :)
