Social Proof is an element that pops up little alerts to help visitors see when other people have donated, and to allow them to click to give from those alert popups. Clicking to donate from a Social Proof popup for a given donation opens the same campaign checkout as that donation.

For example, if a Social Proof element shows a popup when someone donated to the Support Tommy campaign, clicking that popup would open the Support Tommy campaign’s checkout flow, and finishing the donation would attribute it to that campaign.

As such, if you want to allow people to make donations through Social Proof to a specific campaign or set of selected campaigns, that Social Proof element can only show donations made towards that campaign or campaigns.
