's always indicates possession, never plurality. I don't think there's a hard-and-fast choice between "IDs" and "ids", but "IDs" looks better to me, since it's clear that you're using an abbreviation. But if you write "id" (singular), be consistent and write "ids" (plural).

If I write in the documentation "Cross referencing with unique IDs is hard to document" do I then write ids IDs id's or ID's ????
