Our payment form cannot be altered. However, you can send us any additional information at the time of the sale and we will pass it back to your return URL when the sale is approved. For more information on this please reference the ‘Custom Parameters‘ article.
Alternatively, you can have the buyer sent back to a form on your site after the sale. This way, the buyer could send all extra details directly to you. If you are working on constructing a return script, keep in mind that you can use our developers.2Checkout area to test your script and make sure that it is working properly when you go to implement it as part of your purchase process.
