aiohcaptcha

AsyncIO client for the hCaptcha service
Secure your forms using a captcha.

pip install aiohcaptcha

Usage
Configuration
You can define the secret key HCAPTCHA_SECRET_KEY in the environment or directly pass it to the HCaptchaClient model as a parameter.
Get the secret and public keys from the hcaptcha.com.
Template
<div class="h-captcha" data-sitekey="your_site_key"></div>
<script src="https://hcaptcha.com/1/api.js" async defer></script>

Check hCaptcha docs for more details on the HTML widget.
View
from aiohcaptcha import HCaptchaClient

response_token = request.POST["h-captcha-response"]
client = HCaptchaClient(secret_key)
verified = await client.verify(response_token) # a boolean

You can adjust it to any Python Web framework that has async view support.
If you are sending the form data using an AJAX request, use $('textarea[name=h-captcha-response]').val(); for the captcha key.
Response details
Response details are stored in client.response,
details of the HCaptchaResponse model is same as the JSON response provided in the hCaptcha documentation.
Extra arguments
You can also add remote_ip and sitekey (expected key) to the client.verify function.
These parameters are explained in the hCaptcha docs.
For unit testing, you can create the Client HCaptchaClient with debug=True parameter.
In this mode, the verify function will return True if the user_response token and sitekey parameters do match, otherwise it will return False:
client = HCaptchaClient("<SECRET_KEY>", debug=True)
assert await client.verify("<USER_TOKEN>", sitekey="<SAME_TOKEN>")
assert await client.verify("<USER_TOKEN>", sitekey="<DIFFERENT_TOKEN>") is False
