WiscWeb - Adding CAPTCHA to Gravity Forms

This document will walk you through the process of creating a reCAPTCHA account for your site and adding the reCAPTCHA keys to Gravity Forms in your WiscWeb project. These instructions assume that you already have a Google Cloud Platform account setup for your group and that your website is already launched. Note: reCAPTCHA is a type of CAPTCHA, developed by Google.


What is CAPTCHA?

CAPTCHA is a simple test that allows the browser to distinguish between a human user of your form and machine input by a bot. Adding it to your web forms will allow you to restrict submissions by bots, which will cut down on the amount of spam emails that come in to your department.

Here's an example of reCAPTCHA, the form we encourage you to use with your WiscWeb forms:

Creating a reCAPTCHA account

Note: We highly encourage you to set up your CAPTCHA account using a service account rather than a personal account. That way, if you were to leave your position, your team can still access and modify the information in the account. These steps will assume you are using a service account for this process.

  1. Open a new incognito or private browsing window in your browser

  2. Navigate to https://www.google.com/recaptcha/admin

  3. Type in your NetID email (netID@wisc.edu) into the "Email or Phone" field and click the blue Next button (reminder: you'll eventually be logging into a service account)

  4. You should be redirected to the Shibboleth login screen. Login with your NetID credentials

  5. You will be asked which account you'd like to sign into. The various options will appear in a bulleted list. Select the service account you'd like to set up the CAPTCHA account with. 

  6. If asked what type of CAPTCHA account you want, choose reCAPTCHA enterprise. 

  7. You should now be logged in to Google's reCAPTCHA tool with your service account. If not already brought to the "Register a new site" page, click on the plus icon in the top right corner of the screen.

  8. In the Label field, type in the name of the website you'd like to add CAPTCHA for

  9. Choose the first option, Challenge (v2), from the reCAPTCHA type list and select the "I'm not a robot" option

  10. Click the plus sign (+) in the Domains list to add a new URL for your reCAPTCHA account (no need to add the https://).You may add more than one domain, if desired.

    Type in the domain for your reCAPTCHA account

  11. Note: If you have not yet launched your WiscWeb site, you will have to add your production domain to this list when you launch.

  12. In the Google Cloud Platform section, add a project name and choose an organization this should fall under. If you have not yet created a Google Cloud Platform (GCP), you will need to request one from the Cloud Services Team (i.e. don't use the default wisc.edu account). Once setup, your new GCP account should show up as an option in this list.
    Note: For UW-Madison websites, it is highly recommended that you get an official, supported GCP project, provisioned by the DoIT Cloud Services team. A UW Cloud Team provisioned GCP account/project will have a Google group as its primary Owner/principal, making it easy and simple to provide appropriate team access to the GCP project. Owners will have the ability to manage the users in the group.
