Meta is the company that owns Facebook and Instagram, and it is where Markettai publishes your ads and your posts. Without that connection the app cannot publish anything on your behalf.

1. On the "Meta" step of sign-up, or from your profile at any time, you click the connect button.
2. You sign in with your Facebook account and accept the permissions it asks for: managing ads and managing your pages.
3. Markettai syncs your Facebook pages and your ad accounts on its own.
4. You check which ones ended up connected. You can add more or disconnect any of them from your profile.

If you later create a new page or change ad account, you come back to this same step from your profile. There is no need to go through sign-up again.

The most common mistake when starting out is unticking one of the permissions on the Facebook screen. If you do, the connection is left half done and a warning will appear (see «What each Meta connection warning means»).
