Can a gift amount be passed into an Optimized Donation Form popup from an external button?

Jennifer Deschain

Hi all,

I have a donation widget on our WordPress website that lets visitors select a gift amount ($50, $100, $200, $500, or a custom amount). When they click "Donate Now," our RE NXT Optimized Donation Form opens as a popup using the standard Blackbaud loader script and data-blackbaud-optimized-form-id button method.

Everything works correctly; the form opens as expected. What I'm trying to figure out is whether there's a way to pass the amount the visitor selected on our website into the form, so that amount is pre-filled when the popup opens.

I've reviewed the URL parameter documentation (designation, campaign, appeal) and don't see an amount parameter listed. I also tried appending ?amount= to the page URL before the popup fires, but that had no effect.

Here is the test page where the widget is live so you can see exactly what I'm describing:

My questions:

1. Is there a supported URL parameter for pre-filling a gift amount in an Optimized Form?
2. If not, does the Blackbaud loader script expose any JavaScript method that would allow an amount to be passed in programmatically when the popup is triggered?

Thanks in advance for any help!
