Convert Your Paya Account for Testing

Before processing any live transactions, you should test your integration using test transactions. To test your transactions, you must convert your Virtual Terminal Account into a testing environment.

  • Log in to your Paya Virtual Terminal Account.
  • From the Home tab, scroll down to the Account Overview section and click Switch under Mode.
  • Click Confirm.

Install and Configure Chargent

If you haven’t installed Chargent yet, follow the step-by-step Installation and Setup Guide.

Verify Your Gateway Credentials

During the setup process, you must create a Gateway record and verify your Paya credentials using the Gateway Setup Wizard.

Initially, we recommend creating a gateway specifically for testing. If you are in the testing phase, select the ‘Test Transactions’ tab when verifying your credentials.

  • Merchant ID (MID)
  • Merchant Key

For more information about the Gateway Setup Wizard, including troubleshooting tips, visit our Gateway Setup Wizard documentation.

Test Your Integration

After completing the Installation and Setup Guide, follow our Testing Chargent Guide. Use Paya’s test credit cards, test account numbers, and test response codes to ensure that your gateway is integrated correctly before going live.

Testing Response Codes

It is important to test for various response codes to ensure that your transactions are processed as expected. To generate specific response codes, AVS responses, and CVV2 responses, the transaction amount can be used to generate a desired value.

For a list of transaction amounts used to generate specific response codes, see Paya’s Test Data documentation.

To learn more about Paya’s response codes, visit the Response Codes section of this guide.

Sending Live Transactions from a Sandbox

To avoid unintentionally processing live transactions in your sandbox, Chargent’s Paya integration does not allow you to test live transactions in a Salesforce sandbox. We recommend testing all live transactions in Production.

Address Verification System (AVS)

Paya includes Address Verification System (AVS), a system used to prevent fraud and validate the ownership of a credit card by checking the billing address of a credit card with the data on file at the credit card issuing company.

You can change the AVS Settings for your Paya Account by visiting How to change the Address Verification (AVS) Settings in Paya Exchange.

Response Codes

Response codes are saved in the Reason Code field of Transaction records in Salesforce. A response code is specific to your gateway provider and explains why a transaction was successful, declined, or encountered an error. Use the Reason Code field, along with the Gateway Response field, to troubleshoot your transactions.

For a list of Paya’s response codes and their description, please see Paya’s Decline Codes.

Paya also provides codes related to Address Verification System (AVS). AVS codes are saved in the AVS Response Code field of transaction records in Salesforce. See Paya’s MasterCard and Discover AVS Codes for more information.
