I have latest Ubercart 7.x-3.6 on Drupal 7.31 installation. I want to add a form on cart/checkout/complete page. which api can I use to add a form on checkout complete page.
Ubercart's core cart checkout complete page contain an order submit message and created order link, right? Now I want to add a form bellowed to the contents of checkout complete page. I think its enough detail.
