Distinctives for the Realex Gateway

Realex Payments offers two types of transaction refunds, refunds and rebates. Rebate is the default type, and will refund money to the same credit card for the initial transaction. The refund amount limit for a rebate is 115% of the original transaction value.

If you want to refund any amount of money to any credit card any amount of money, choose the refund type. This is available in the custom settings. In the Chargent Settings tab, click the Advanced Settings tab and then check the box for Use RealEx Rebate Method.

  8. A record is created for each error and each successful transaction, and this record contains the response messages and details that are sent back from Realex. See the figure below for an example.

    Realex Chargent Transactions

Sending Live Transactions from a Salesforce Sandbox

When Chargent is installed in a Salesforce Sandbox, transactions are always sent to the payment gateway's test / sandbox / development environment, regardless of whether Chargent's Test Endpoint checkbox is checked. This is done as a security precaution, to prevent real transactions from being accidentally sent from a Salesforce Sandbox.

When Chargent is installed in a production or developer Salesforce org, the Test Endpoint checkbox on the Gateway record will select between sending to the payment gateway's live and test environments. (There are a few exceptions, such as Stripe, which has a single endpoint to send transactions to, and different credentials for live versus test transactions).

If you wish to send live transactions from a Salesforce Sandbox, as a final step in testing, simply use Chargent's Endpoint Override field on the Gateway record, and enter the production endpoint of your chosen gateway there.

Here is the production endpoint URL for Chargent's integration with Realex:

Note that the full endpoint URL must be entered in the Endpoint Override field, and the domain must be present in the Remote Site Settings (for standard Chargent integrations it should be already present).

Understanding Transactions

When a transaction occurs between Chargent and the Realex gateway, a new transaction record is created in Salesforce. The listing of transactions can be found in the Transaction section near the bottom of the Chargent Order page (or Opportunities or Cases, if you are using those packages). See the figure above.

On the order page, scroll down to that Transactions section and click a Transaction ID link to see the details, as shown in the figure below. This transaction record contains the entire set of data that Realex sends in its response, including transaction Type (Charge, Authorize, Refund or Void), the Response Status (Approved, Declined, Error), and any related approval or error messages.

Verifying Transactions in the Realex Dashboard

You can compare the transaction records in Salesforce with the records in your Realex dashboard. Login to the Realex test portal and click the Batched link at the top. See the figure below.

Realex Verifying

You’ll see a transaction listing similar to this one.

Realex Verifying

Locate the transaction of interest in the listing, and click on the transaction row, then click again on the item of interest on the next page to see the details for that transaction.

Correspondence in the Transaction Fields

The Salesforce Gateway ID is the Realex Pas Ref combined with the Realex Order ID, with an underscore between them.

Moving to Production

This section contains the procedure for configuring the integration in a production system.

Get your Production Credentials

In the same email that contains your credentials you also find a Shared Secret and Refund Password, merged by a "@" symbol (for example, “secret@refund) This is the value for Merchant Security Key in Salesforce.

Production account: You’ll also need to register for a production account. When you’re ready, use the contact information in the enrollment email messages to work with Realex Support and obtain the same set of credentials for your production account.

NOTE: It’s important that you do not proceed here until the testing procedure described in Testing the Integration is successful.

Follow these steps to configure the production in Salesforce:

  1. First, obtain the production credentials for the Realex production gateway account (similar to the method given for sandbox credentials in Obtain a Realex Sandbox Account.

  2. Get these production credentials from your enrollment email message(s):

    • User ID
    • Password
    • Realex Shared Secret and Refund Password, merged by a "@" symbol. For example, “secret@refund". This will be the Merchant Security Key in Salesforce.

  3. Repeat the steps in the Configuring Salesforce for Realex Integration section above, but substitute the production credentials.

  4. Repeat the steps in the Testing the Realex Integration section above with respect to the SalesForce production environment, using the production credentials.

    Void a transaction: If you’re using an actual credit card and want to prevent the charge from settling, remember to void the transaction after testing.

  5. Be sure to successfully transmit at least one real credit card transaction using company or personal accounts. We recommend that you submit a transaction with a very small amount and then void that transaction afterwards. This ensures that the system works with your production credentials.
