Prerequisites

• 1.
  Meta Business Account: You need a verified Business Manager account with admin access
• 2.
  Ad Account: Active ad account with payment method and spending history
• 3.
  Developer App: Create an app in Meta for Developers portal
• 4.
  Access Tokens: Generate system user tokens for server-side automation

API Access Levels

Step 1: Create a Meta App

1. Go to developers.facebook.com
2. Click "My Apps" → "Create App"
3. Choose "Business" type
4. Fill in app details
5. Add "Marketing API" product

Step 2: Generate Access Token

1. Use Graph API Explorer
2. Select your app
3. Get User Access Token
4. Add required permissions

1. Business Settings → System Users
2. Create new System User
3. Assign Ad Account assets
4. Generate permanent token

Step 3: Install SDK

pip install facebook-business

npm install facebook-nodejs-business-sdk

Step 4: Initialize API Client

# Python example
from facebook_business.api import FacebookAdsApi
from facebook_business.adobjects.adaccount import AdAccount

# Initialize the API
FacebookAdsApi.init(
    app_id='YOUR_APP_ID',
    app_secret='YOUR_APP_SECRET',
    access_token='YOUR_ACCESS_TOKEN'
)

# Get your ad account
account = AdAccount('act_YOUR_ACCOUNT_ID')
print(account.api_get(fields=['name', 'account_status']))

What is Dynamic Creative?

Meta automatically combines your creative assets (images, videos, headlines, descriptions, CTAs) to find the best-performing combinations for each audience segment.

Example 1: Complete Campaign Automation System

End-to-end campaign creation with dynamic creative and custom audiences:

import pandas as pd
from facebook_business.api import FacebookAdsApi
from facebook_business.adobjects.adaccount import AdAccount
from facebook_business.adobjects.campaign import Campaign
from facebook_business.adobjects.adset import AdSet
from facebook_business.adobjects.adcreative import AdCreative
from facebook_business.adobjects.ad import Ad

Example 2: Real-Time Performance Optimization
