Simplify Commerce

The Simplify Commerce plugin extends WooCommerce allowing you to take credit card payments directly on your store.

Please note: Service only available to US merchants.

To function, Simplify Commerce requires:

  1. A server with CURL support (to communicate with the API)
  2. PHP 5.3+ (a requirement of the SDK used)
  3. WooCommerce 2.0+
  4. SSL/HTTPS setup to keep customer data safe

Installation ↑ Back to Top

  • Unzip and upload the plugin’s folder to your /wp-content/plugins/ directory
  • Activate the extension through the ‘Plugins’ menu in WordPress
  • Go to WooCommerce > Settings > Payment Gateways > Simplify Commerce to configure the plugin

For more information on installing and managing plugins see here

Setup ↑ Back to Top

On the settings page you should configure the gateway.



The usual enable, title and description fields are present as well as the following Simplify specific options:

  • Sandbox – Enable  sandbox mode to allow testing mode. This lets you use the test cards found here: Sandbox mode does not require SSL.
  • Sandbox Private Key – From your simplify account > Settings > Api Keys. New accounts should have a sandbox account pre-created.
  • Sandbox Public Key - From your simplify account > Settings > Api Keys.
  • Private Key – This is your live key from your simplify account > Settings > Api Keys for live payments. SSL is needed.
  • Public Key - This is your live key from your simplify account > Settings > Api Keys for live payments. SSL is needed.

On the checkout ↑ Back to Top

Customers pay on the checkout page. When Simplify Commerce is selected the credit card form will be displayed:

Checkout form

This form tokenises the input details using simplify commerce’s javascript library – this ensures CC details are not posted to your server which makes the process more secure.

In live mode, SSL must be enabled in order to use Simplify Commerce.

I’m getting an API error

Ensure you have input the correct keys and that if you are in live mode, you have entered live keys (not test keys).

Does this extension support automatic subscriptions?

At present, no. But it will work with subscriptions in manual mode.

Terms and Conditions

Simplify may ask that the website contains a Terms and Conditions page before approving your account. If you need help setting this up, please refer to the Checkout Page section on the Configuring WooCommerce Settings documentation.
