Phase 1 — Meta Business Manager (Do This First)

Why first: Meta verification takes 2–5 business days. All Instagram and Facebook accounts for all brands are blocked until this is complete. Start here and let it run while you do other platforms.

Step 1.2 — Verify Eureekka SA as a Business

  3. Select Business (not individual)
  4. Choose verification method — Document Upload is fastest:
  5. Upload one of: Certidão Permanente, Tax registration document (NIF), or bank statement with company name and address

Important: Until verification is approved, you can still create pages — but API access and advertising will be limited. Do not wait for verification before continuing with Step 1.3.

Step 1.3 — Create Facebook Pages (one per brand)

For each brand (Gamine, CateringAssiste, Gestso, Down a Rabbit Hole):

  1. In Business Manager → Pages → Add → Create a New Page
