Prefill a standard In Memory of field on a giving form

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.

In Generate Autofill Links, select the existing pre-payment field in_memory_of under Select a field, enter the honoree name, and click Insert this field into the URL. Copy and test the generated link. For the standard In Honor of field, use in_honor_of instead. The tool formats the URL for you; you do not need to construct the parameters manually.

This fills the existing text field; it does not create a missing field or select a separate custom tribute-type dropdown. If the form uses a custom combined tribute question, inspect its actual field key and exact option value instead of assuming these standard keys apply. The generic URL mechanism uses pre-payment field keys, so do not assume that it prefills an arbitrary post-payment question. Test the actual donor form, including any existing personalized/token link, before distributing it; URL parameters can be visible and editable by recipients.
