Using the Payment Form in Advanced Editing Mode

Customizing the Payment Form

For simple customizations to the payment form, like changing a header or field name, you should not have to use Advanced Editing mode. Click here for more information about simple edits.

To perform advanced edits to your payment form, log into your merchant account and go to Settings -> Payment Forms -> Select the desired form -> Select the 'Template' section -> then select 'Advanced Editing'.

Please Note: Once you choose to use the advanced editor, you will no longer be able to use the template editor for this payment form.

A list of form fields can be found at the bottom of this page. Example templates for common use cases for the form can be found below. Please keep in mind that not all examples will be useful for every merchant. You may need to do further customization once you've added the example code to your form in order to have it function properly. Make sure you've tested your form before you make the link public!

For example if you post a form with the field "comments" to the gateway and set UMredirApproved to then the gateway will redirect to Please Note: Use of this feature is not recommended for security reasons.

Payment Form via POST

The merchant can also post data directly to the payment form. The merchant's website would just need to present the customer with an HTML page containing the code below. The form action line should replace the example link Form Link found at the top of the payment form page in the console:

<form action="">
<input type="hidden" name="key" value="[key]">
<input type="hidden" name="command" value="sale">
<input type="hidden" name="amount" value="[amount]">
<input type="hidden" name="invoice" value="[invoice]">
<input type="hidden" name="hash" value="[hash]">
<input type="submit" value="Continue to Payment Form">

Any form fields will be managed by the API. If you create a custom payment form, you must make sure to include a hidden form field for any field you wish to pass through to the API.

If the amount will not be fixed, but will instead be entered manually by the merchant, change the input type from "hidden" to "text" as shown below:

<code html>
<form action="">
<input type="hidden" name="key" value="[key]">
<input type="hidden" name="command" value="sale">
<input type="text" name="amount" value="[amount]">
<input type="hidden" name="invoice" value="[invoice]">
<input type="hidden" name="hash" value="[hash]">
<input type="submit" value="Continue to Payment Form">

Developer Reference

Address Verification System

These AVS codes are returned in the UMavsResultCode variable, and serve to provide developers with greater control over the AVS System. Many developers may choose to capture and display the UMavsResult variable instead. The UMavsResult variable contains the meaning of the code, rather than the code itself.

YYY Y, YYA, YYD Address: Match & 5 Digit Zip: Match
NYZ Z Address: No Match & 5 Digit Zip: Match
YNA A, YNY Address: Match & 5 Digit Zip: No Match

N No Match
P Not Processed
S Should be on card but not so indicated
