Campaign unique backend identifier

Open Online Giving → Campaigns or Online Giving → Forms, select the campaign or form, then go to Tracking & Analytics → Links & Appeal Codes. Older interfaces may label this Unique Tracking Links.

With newer form settings, open Links & Appeal Codes → Internal Reporting, enter Unique Backend Identifier and Save Identifier. Other giving-form layouts expose the same administrative-identifier section in form settings. NXT gift-export institutions can select a Blackbaud appeal Lookup ID, not its System ID. This is an internal reporting/integration identifier, distinct from the public permalink and designation ID.
