Facebook Fundraiser donations will automatically credit the fundraising page if the fundraiser was created from your Fundraising Center.
If the donations are not appearing, it may be that the Facebook Fundraiser was directly created on Facebook, which does not link to your walk fundraising. These donations will be sent to the Autism Speaks as a general donation.
Can I connect an external Facebook fundraiser to my personal page?
Unfortunately, no. You do have to create your fundraiser through the fundraising center for it to be tied to your walk page.
All existing donations from your existing Facebook fundraiser can't be redirected. To make sure
that all future donations are reflected in your fundraising goal, disable the existing fundraiser
so your Facebook friends aren’t confused by the two fundraisers and create one from within your walk account.
