Overview

A system user access token lets your app call the Facebook Graph API on behalf of a Business Manager, without any per-user OAuth login. You need one thing to connect: a system user access token.

​

Prerequisites

• A Meta Business Manager account with admin access.
• An app created in that Business Manager (added under Business Settings > Accounts > Apps).

​

Instructions

​

Step 1: Generating a system user access token

1. In Business Settings, go to Users > System Users.
2. Click Add, name the system user, and choose a role:
   • Admin — gets access to all assets in the Business Manager automatically.
   • Employee — needs assets assigned to it individually (see next step).

3. Open the system user you just created, click Assign Assets, select Apps, choose your app, and grant it at least Manage app access.

4. Reload the page and confirm the app shows Full Access.
5. Click Generate token, select your app, choose a token expiration (pick Never for a permanent token — Nango does not run a refresh flow for this integration), and select the permissions your integration needs.
6. Copy the generated token — Facebook only shows it once.

​

Step 2: Authorize in Nango

1. Open the form where you need to authenticate with Facebook (System User Token).
2. Enter your System User Access Token in its respective fields.
3. Submit the form, and you should be successfully authenticated.

You are now connected to Facebook (System User Token).
