WinRed allows you to pre-fill form inputs using URL parameters for your donor's convenience. These parameters allow you to modify, preselect, and prefill a donation or petition page, just by simply adding a value to your WinRed URL. These parameters are available for use on any type of WinRed page.
URL parameters are attached to your WinRed URL first via a "?" and then with a "&" for each additional parameter.
For example here is a URL with no parameters attached.
Say you want the donation amount "$100" to be selected on the page when the donor clicks your link. All you need to do is add ?amount=100 to the link, and it will preselect that donation button.
This is a simple example of one way to use these parameters on your donation page. We have all of the available parameters for use and the field value of the target listed below. If you have questions on a specific one, please chat with our team using the chat box in the right-hand corner and we're happy to help!

Modify Donation Buttons with URL parameters
You can use URL parameters to modify, preselect, and overwrite donation buttons on your page. Each variable and what it does is listed below.
Select a desired donation amount.
Select a desired donation button position. This will preselect a particular donation button, regardless of the amount changes (either through page edits or through features like Dynamic Amounts). Read more here.
You can manipulate the donation amount shown to a donor using this parameter. For example, if you want the first donation button to always have a value of $5, regardless of other settings, you would add ?amt1=5 to the URL string.
