On Perform Transaction -- Step 2 page, complete the appropriate fields to complete the Credit transaction.
Be sure to enter information for all fields denoted by an asterisk.
Your Payflow account was configured by your administrator with several transaction security settings. One of these settings is a limit on credit that causes the system not to allow the cumulative amount credited against any transaction to exceed the amount of the original transaction. If, instead this credit limitation is not in effect for your account, then the system will allow the cumulative credit amount to exceed the amount of the original transaction. An unauthorized credit of this nature constitutes fraud, so take care to ensure that you know how much money might already have been credited against the original transaction. Check with your Payflow account administrator about this setting. Refer to Transaction Settings for details.
The Amount field displays the original transaction amount. You can use the came amount, or change it to credit partial amounts (refer to the note above). Use a positive number and include a decimal point and cents (00 if no cents are involved). For example, 42.00.
Enter Comments about the transaction. For example, you can enter order tracking information like order ID or confirmation number. The comments are saved with the transaction data and appear in PayPal Manager reports.
Verify the information and click Submit to submit the transaction.
