In n8n, add a Facebook (or Meta Graph API) node, then create new credentials. You’ll authenticate with a Facebook account that has access to the Page, ad account, or asset you want to automate. Approve the requested permissions, then select the Page/ID inside the node. Honestly, most connection issues come from missing Page roles or using the wrong Meta Business. If a workflow needs webhooks, verify the callback URL and re-subscribe to events.

A lot: capture Facebook Lead Ads and send them to Google Sheets or HubSpot, alert your team in Slack when a Page message arrives, and generate daily performance summaries with OpenAI. You can also log comments, tag conversations, trigger follow-ups, and archive key metrics for reporting. Some teams auto-create tasks for hot leads, while others build “inbox to CRM” pipelines so nothing slips. Start with one workflow, then expand once it’s stable.

Yes—n8n needs a Facebook login with the right access to the Page, ad account, or Business Manager asset you’re automating.

Permissions and review rules are the big ones. Certain data (especially around ads, messaging, and user info) requires specific scopes, Page roles, and sometimes Meta app review, so a workflow may work in testing but fail in production. Webhook events can also be picky: if your n8n webhook URL changes, Facebook stops delivering updates until you re-verify. Rate limits apply, too, so batching writes to Google Sheets or your CRM is often smarter than firing one update per event.
