The current integration that just rolled out between JustGiving and RE NXT only allows us to set the fund, campaign and appeal in NXT at the JustGiving campaign level. We currently have lots of fundraisers within each of our JG campaigns and they all go to different funds so the integration doesn't work well for us - tons of manual clean up. We also have to do lots of manual work since the integration doesn't pull over any credit card information or indicate whether a donor clicked the donation boost button or not.
Our suggestions for building out the integration functionality:
Allow setting the default fund at the page level (not just at the JG campaign level).
Bring over credit card information to the gift: card type, card number, cardholder name, expiration date.
Add functionality to show whether a donor chose to cover the donation boost processing fee or not.
Add functionality to do gift attributes and to add In Honor Of and In Memory Of to the gifts.
Allow functionality to have gifts automatically marked as Acknowledged since they receive the JustGiving receipt.
