Storing strong API credentials

How are the API credentials stored normally?

Your settings are stored in the WP database, which means that an SQL exploit may result in access to your settings key data. While such an exploit also has access to the rest of the database as those settings are unencrypted, it does leave the potential for an exploit. Other payment gateway plugins implement the same procedure when saving the API credentials, but we’d like to offer something different to protect your data.

How will the API credentials be stored using our new feature?

You can now define your website’s credentials; this means that the settings are no longer stored in the database. Should a hacker gain access to the database, the settings are not visible to them.

What are the steps to define the API logins on my website to enable this feature?

Step 1

Before proceeding, please create a backup of your site as you will be editing your theme/website files as a preventive measure if you have accidentally deleted any code. You can ask your hosting provider to backup your site for you.

Step 2

You would need to use the code below and replace the required credentials for your ePDQ account below:

// This stops anyone from editing the plugin files within the WP admin
define(‘DISALLOW_FILE_EDIT’ , true);

define( ‘secure_pf_PSPID’, ‘#replace with PSPID for account#’ );
define( ‘secure_pf_SHA_in’, ‘#replace with SHA in for account#’ );
define( ‘secure_pf_SHA_out’, ‘#replace with SHA out for account#’ );
define( ‘secure_pf_SHA_method’, ‘#replace with SHA method for account#’ );

Once you have replaced it with the correct information, copy and paste the code on your theme’s functions.php file.

The quickest way to add these would be to add them to your theme’s functions.php file from your:
WordPress dashboard > Appearance > Theme Editor > click the functions.php from the file selection.

After that, kindly click the Update File button for the changes to be applied.

We recommend that you add the above code into the wp-config.php file via FTP.

Alternatively, you can also use a third party plugin like the Dessky Snippets plugin to add the code instead of manually adding it on your theme’s function.php file.

Note: If you have followed the steps above, it will take priority over the normal way of storing the API credentials.

What can I do to process refunds?

If you’d like to process refunds, you’ll have to add the code below using the same process above.

define( ‘secure_pf_userid’, ‘#replace with API user ID from account#’ );

define( ‘secure_pf_pswd’, ‘#replace with API  password from the account#’ );

define( ‘secure_pf_refid’, ‘#replace with API  Ref ID from the account#’ );
