Django reCAPTCHA Integration

Kim Majali wrote on 13/11/2023

1. Get a reCAPTCHA Account

Visit google.com/recaptcha Create Account
Choose V3
Add domains
Get keys and save them in settings.py


# reCAPTCHA
GOOGLE_RECAPTCHA_SITE_KEY = '6LfHCw0pAAasddasdasd'
GOOGLE_RECAPTCHA_SECRET_KEY = '6LfHCw0pasdasdasdasdas'

2. Create a reusable function to validate reCAPTCHA

install the request packages


pip install requests

We choose lib.py to create our reusable function


from django.conf import settings
import requests

def validate_recaptcha(request):
''' reCAPTCHA validation '''
recaptcha_response = request.POST.get('g-recaptcha-response')
data = {
'secret': settings.GOOGLE_RECAPTCHA_SECRET_KEY,
'response': recaptcha_response
}
r = requests.post('https://www.google.com/recaptcha/api/siteverify', data=data)
result = r.json()

return result

Using reCAPTCHA

3. Edit the template

On any template, you want to use reCAPTCHA, add the reCAPTCHA field and script to the desired form

4. Edit the view

to the view


from .lib import validate_recaptcha

def my_view(request):
  if request.method == 'POST':
    # do your form validation
    if validate_recaptcha(request):
      #Save
    else:
      print('wrong recaptcha')
