How to set up the credential in n8n

In n8n, open Credentials → Create credential and pick Header Auth.
Fill in the two fields:
NameAuthorization
ValueBearer <your token>
Open the pasted node. Authentication is already Generic → Header Auth; choose the credential you just made.
Use a System User token from Meta Business settings; the token on the API Setup page expires within hours.Source (opens in a new tab)Source (opens in a new tab)

Your token lives in n8n only. I never ask for it.

Don't have time to build it? I'll build it for you.
