This module provides a Drupal admin side interface to manually purge Acquia Cloud varnish cache. It also validates Acquia cloud credentials. We can flush varnish cache for each domain that we have. It uses the acquia cloud API functions for all the actions.

Acquia Flush Varnish
What is Acquia Flush Varnish ?
Acquia Flush Varnish provides a Drupal admin side interface to manually purge "​Acquia
Cloud​" varnish cache. It also validates Acquia cloud credentials. We can flush varnish cache for
each domain that we have. It uses the ​Acquia Cloud API functions​ for all the actions.

How is this secure ?
It uses custom ​CSRF token​ in Drupal 8 and Form API confirmation in Drupal 7 for clearing
varnish cache. It also uses ​Drupal http request​ for all API calls. So it's not vulnerable to CSRF
exploits and avoids security risk.

2. How did I get this idea ?
This is one of the case encountered in ​Global Atlantic​ project. We got an issue where taxonomy
term updates were not reflected for anonymous user pages because of varnish cache. So we
decided to create a Drupal admin side panel to purge Acquia varnish cache instead of the client
having to be dependent on us to clear the cache every time. After analysing Acquia cloud API
functions this module was implemented. It’s also very useful module for Drupal developers and
non technical people as it saves developers time while implementation.
Steps to configure the module:
● Download and install a module as usual. See ​Drupal 7​ and ​Drupal 8​ for further
information.
● Go to ​Administration » Configuration » Acquia cloud API Credentials
(/admin/config/flush­varnish).

3. ● It shows a configuration form. In that form provide your Acquia API valid
credentials.(Below I have enclosed how to get Acquia credentials)
● Click ​“Save API Values”. ​It validates and displays confirmation message for
your setup.
● Then go to ​Administration » Configuration » Acquia cloud API Credentials
» Acquia varnish cache ​to clear a varnish cache.
How to get Acquia credentials?
Login at ​https://accounts.acquia.com/account​ this URL using your Acquia account credentials.
After login go to credentials tab. In credentials tab we have Acquia cloud API credentials (Email
and Private Key) below "​Cloud API​".
What are the restrictions ?
It only works for Acquia hosted sites.
