Dragon Forms URL Structure and Appending Parameters

Dragon URLS with parameters attached should follow the format shown below. That is, it should begin with the base Dragon form URL, include a ? before the first parameter, and an & before each additional parameter.


  • Blue: Dragon form URL
  • Red: the ? indicates the beginning of a query string. This must always be used if you want to append parameters.
  • Green: indicates the various parameters appended to the URL. Examples would be pk=promokey,, r=encrypted_customer_id, etc.
  • Purple: the & indicates that an additional parameter is being added to the URL

In most cases, you should use the live URL in the format shown above. However, there are some instances where the publisher has been using the longer form of the Dragon form URL shown below. In this case, the form context has been included as the first parameter following the ? query indicator. In this case, add the next parameter with an &.
