Capturing Donation Info

Hi, we are a charity and use a plugin called GiveWP to handles donations, essentially someone fills in a form and donates. When they donate they get redirected to a dedicated confirmation page that shows info on the donation. Our analytics company want to use be able to access this donation information and have asked us to open up the datalayer to do so!! we are a bit lost with this so tried your plugin and they said no change?

Any ideas or help would be amazing!
