PayEx

PayEx for WooCommerce allows you to take payments via PayEx, a leading Scandinavian online payment service provider, using these currencies:

• Danish Krona
• Euro
• Norwegian Krona
• Swedish Krona

The user is taken to PayEx to make a secure payment, then back to your store and shown the Thank You page.

• A PayEx account
• An SSL certificate

• Purchase and download the plugin zip file from WooCommerce.com
• Login to your WordPress Admin. Click on Plugins | Add New from the left hand menu
• Click on the “Upload” option, then click “Browse” to select the zip file from your computer. Once selected, press “OK” and press the “Install Now” button.
• Activate the plugin.

• Go to: WooCommerce > Settings > Checkout > PayEx.
• Select and enter:
  • Enable/Disable  – checkbox for this gateway.
  • Title – allows you to determine what your customers will see this payment option described as on the checkout page.
  • Description – controls the message that appears under the payment fields on the checkout page.
  • Account Number – Requested from PayEx.
  • Encrypted Key – Requested from PayEx.
  • Purchase Operation – The way that purchases are handled. Authorization means a 2-step transaction (where you as a merchant approve/authorize each payment) if the payment method allows this. Sale means a 1-step purchase.
  • Language – The language in which the page will be opened when the customer is redirected to PayEx.
  • Test Mode – Activate this feature if you want to make purchases against PayEx test environment.
  • Debug – If this option is checked then details of communication with PayEx are stored in a debug log at location /wp-content/plugins/woocommerce/logs/payex.txt.
  • Save changes.

To get the payment gateway working as expected you have to make some settings changes in your PayEx account.

To enable the communication between PayEx and your store, you need to specify a Callback URL.

• Click on Merchant Profile in the left hand menu.
• Callback method – choose URL
• Transaction callback URL/Mail – https://yourdomain.com/?wc-api=WC_Gateway_Payex_PM (in test mode http will work instead of https)
• Press Save.

Instructions about how to create an Encryption key. This key should be entered in your WooCommerce PayEx settings.

• Click on Merchant Profile in the left hand menu.
• Click on New encryption key.
• Click on Save encryption key.
• Press Save.
• PayEx recommends replacing the Encryption key at least once a year.

In production you need to specify your servers IP-address to be able to make API-calls against PayEx. This is not needed against the test environment.

• Click on Merchant Profile in the left hand menu.
• Enter your server IP-address.
• Press Save.

Remember that it can take up to 15 minutes before the changes take effect.
