Step 1: Get a Facebook Access Token For Instagram

1. Go to Meta for Developers

2. Log in and go to My Apps

3. Create a new Business App (or use an existing one)

4. Open the Graph API Explorer from the Tools section

5. Select your app from the top-left dropdown

6. Click “Get Token” → “Get User Access Token”

7. Enable the following permissions:

   • pages_show_list

   • pages_read_engagement

   • pages_read_user_content

   • public_profile

8. Click Generate Access Token

9. Copy and save the token — you’ll paste this into the tool

⚠️ Short-lived tokens last 1 hour by default. You can extend it via the Access Token Debugger tool.

Step 2: Get Your Page ID

1. Visit this URL (replace YOUR_ACCESS_TOKEN):

   bash

   CopyEdit

   https://graph.facebook.com/v19.0/me/accounts?access_token=YOUR_ACCESS_TOKEN

2. You’ll receive a list of Facebook pages you manage.

3. Each page object contains a field "id" — that’s your Page ID

4. Copy this Page ID for later use.

Step 3: Get Post ID (for the Post You Want to Analyze)

1. Use the Page ID to list recent posts. Open this URL:

   bash

   CopyEdit

   https://graph.facebook.com/v19.0/PAGE_ID/posts?fields=id,message,created_time&access_token=YOUR_ACCESS_TOKEN

2. You’ll see a list of posts with their id fields.

3. Copy the full post id (e.g., 1234567890_0987654321) — this is your Post ID
