AAArdvark can be set up to run automatically using the built-in Webhooks integration. This makes it great for running accessibility scans each time you push code to your website and making minimal accessibility issues are introduced.

Automate Accessibility Scans with Webhooks

Pantheon is a popular host for Drupal and WordPress projects. They provide the ability to execute commands as part of the deployment process using a system called Quicksilver.

The example below will trigger a scan for any Pantheon environment that has a valid site id and token in the /files/private/secrets.json file.

Step 1

Set up the Pantheon environment you would like to scan as a site in AAArdvark. This can be your production site, your dev or staging site, or any multidev environment.

Step 2

Add the generic Webhook integration to the site, making note of the URL generated.

Step 3

If you are not already using a secrets.json file with Pantheon, create a new one. Otherwise, you will add keys to your existing JSON file. Use the contents shown at the bottom of the page, substituting your own values for aaardvark_site_id and aaardvark_webhook_token.

Upload the file using SFTP to the /files/private directory.

If you copy the files from this environment to another, you will need to update or remove the secrets.json file in the destination environment.

Step 4

Add the pantheon.yml and /private/scripts/____.php files to your codebase, and push the updates to the environment you have configured.

Going forward, after you push code to this environment, a AAArdvark accessibility scan will be started.
