No. North Macedonia doesn't ask visitors to fill in an online arrival form (also called an entry form, immigration card or landing card) before they travel. Visitors must register with police within 48 hours; hotels usually do this.
Do I still need a visa for North Macedonia?
An arrival form is not a visa. Whether you need a visa or an electronic travel authorization depends on your nationality, so check North Macedonia's official immigration website or your own government's travel advice.
