WooCommerce USA ePay

Overview ↑ Back to top

WooCommerce USA ePay allows you to process payments directly on your site at checkout via USA ePay’s payment processing services. A USA ePay account is required to use this plugin.

An SSL certificate is required to protect customer payment information.

Gateway Mode Comparison ↑ Back to top

Merchants who previously used this plugin with USA ePay’s payment processing will use the legacy payment gateway mode by default. New installs will not see this legacy mode, as it should not be used.

For existing merchants, you can “switch” to the new USA ePay payment method, which adds tons of new features, such as refunds, voids, payment captures, and more. To do so, please go back through the setup documentation below, as you need to generate a new API key to use the new USA ePay API.

Once you’ve done so, you’ll be able to switch over to the newer gateway mode from the Plugins menu by clicking “Use the USA ePay gateway”, and then re-enter your settings to use the newer features.

Extension Settings ↑ Back to top

The settings for the plugin are located under WooCommerce > Settings > Payments > USA ePay Credit Card:

WooCommerce USA ePay: settings

  • Enable / Disable – This will enable the gateway to be used by customers to checkout.
  • Title – This is the text shown for the payment during checkout and on the Order Received page.
  • Description – This is the text shown under the title during checkout. Limited HTML is allowed. If you enable test mode, this section will also display a notice along with test credit card numbers.
  • Card Verification (CSC) – Enable this to require customers to enter their CVV / CV2 (Card Security Code) when checking out. This can be useful if you have requirements in your USA ePay account for CV2 verification.
  • Transaction Type – This controls how transactions are submitted to USA ePay. You may choose either “Charge” or “Authorization”. If you select “Authorization”, you must manually capture and settle payments in your USA ePay control panel or on the WooCommerce orders screen after the transaction has been submitted. This defaults to “Charge”.
  • Charge Virtual-Only Orders – (Shown if Transaction Type is set to “Authorization”) Enable this to force charges on order containing only virtual items so they’re captured immediately instead of authorized (for example, to grant download access right away)
    WooCommerce USA ePay Authorization settings
  • Capture Paid Orders – (Shown if Transaction Type is set to “Authorization”) Enable this to automatically attempt to capture transactions when orders change to a paid status.
  • Accepted Card Logos – This controls the card logos that display during checkout. This is purely cosmetic and has no affect on the cards actually accepted by your merchant account.
  • Detailed Decline Messages – Enable to display detailed messages to customers to provide reasoning for declines when possible instead of a generic error message.
  • Debug Mode – Enable this is you are having issues correctly processing transactions. You can either log API requests / responses directly to the checkout / thank you page, save them to the WooCommerce Error Log (found under WooCommerce > System Status > Logs) or both. All debugging messages are cleaned of sensitive information before display, but as a best practice, please do not enable this unless you are having issues with the plugin.

Connection settings

WooCommerce USA ePay: connection settings

  • Environment – Switch between “Test” and “Production” credentials. Enable “Test” to send transactions to your USA ePay Sandbox Account.

Once you have done this, you can enter a separate API key and PIN for your test account.
  • API Key – Your USA ePay account API Key. Follow the steps above to get this.
  • PIN – Your USA ePay account PIN. Follow the steps above to get this. A PIN is required by our implementation.
  • Receipt Email – Enable this if customers should receive receipt emails from USA ePay in addition to WooCommerce emails.

Merchant Usage ↑ Back to top

Capture Charges from WooCommerce Order Admin ↑ Back to top

Using version 2.0+ of the extension allows you to authorize charges during checkout, then manually capture them later. You can do this via your USA ePay control panel, or can easily do so from the WooCommerce Edit Order page.

You can read more about capturing charges with USA ePay here.

Automatic Refund Support ↑ Back to top

Version 2.0.0 of USA ePay adds automatic refund support. This means that refunds can be processed directly in WooCommerce without the merchant logging into his or her USA ePay account.

You can read more about performing refunds with USA ePay here.

Void Transaction Support ↑ Back to top

Transactions can be voided by using the same workflow as refunds. A void will occur if the transaction has been authorized, but not captured. In the case of USA ePay, voids will also occur for authorized & captured transactions that have not yet been settled. As funds haven’t been transferred, a refund can’t truly be processed.

Voided transactions must be voided in full; partial voids are not accepted by USA ePay. You can read more about voiding transactions here.

Customer Experience ↑ Back to top

Checkout Experience ↑ Back to top

Other Information ↑ Back to top

Detailed Decline Messages ↑ Back to top

When detailed decline messages are enabled, they will provide informative error messages to the customer at checkout when USA ePay returns a useful response.

You can read more about detailed decline messages here.

Test Transactions ↑ Back to top

USA ePay has testing cards available that you can use with a sandbox account to confirm set up is done correctly. Please refer to the testing document for card numbers to use along with the expected responses for each.

Troubleshooting ↑ Back to top

Refund Issues ↑ Back to top

You may see an error message that looks something like this when trying to process an automatic refund:

Oops, you cannot partially void this order. Please use the full order amount.

This means that you’re trying to perform a partial refund, but the charge has not been settled (typically when you try to refund within a day of the purchase). The plugin tries to void this order since the funds have not been transferred (to cancel the order instead of refunding it), but USA ePay does not permit partial voids.

Please wait until the charge has settled (about one day after the charge was made) to refund this transaction.

Other troubleshooting ↑ Back to top

Having trouble with something else? Follow these steps to make sure everything is setup correctly before posting a support request:

  1. Check that your API Key and PIN are entered correctly
  2. Double-check that your API Key and PIN are entered correctly. 😉
  3. Enable debug mode to the checkout page and review the errors messages that USA ePay is providing. Please check these error codes with the USA ePay Response Code Reference. In some cases, such as a transaction being held for review or declined, the plugin cannot change the issue and it must be resolved in your USA ePay account.
  4. Submit a help request and include the debug information for further troubleshooting.
