This is the step that gives your agency access to run ads on your behalf. You keep full ownership of your accounts — your agency gets managed access only.
This process uses Meta's Business Portfolio (formerly Business Manager). It's the safest way to give an agency access — you keep ownership of everything, and you never share your personal login. To get started, you'll need your agency's 15-digit Business ID.
A window will open with three columns. You need to tell Meta exactly what your agency can access:
Opens in a new tab — this page stays open
By adding your agency as a Partner (not a "Person"), you're connecting their business entity to yours. No individual at the agency gets direct access to your personal Facebook profile. If you ever stop working with them, go back to the Partners tab and click Remove — it kills all their access instantly.
Make sure you have a payment method already attached to your Ad Account. Meta often hides unfunded accounts from agency dashboards. Add a credit card to the Ad Account first, then try again.
Once all four steps are complete, your agency has everything they need to start building and launching your campaigns. You'll hear from your team shortly.
