Hey there! I’ve made the switch from the old Instagram API to Graph API too, so I know exactly where you’re coming from. Let me walk you through a straightforward, step-by-step guide to get those basic public details (username, like counts, post dates, image URLs, captions) using Instagram Graph API:

1. First, Get Your Setup Right #

Before diving into calls, you’ll need a few things sorted:

• A Facebook Developer Account: Graph API is tied to the Facebook platform, so head over there to create an app and add the Instagram Graph API product to it.
• An Instagram Business or Creator Account: Unlike the old API, you can’t pull data from regular personal accounts via Graph API. If you’re working with your own account, switch it to Business/Creator first (it’s free and easy to do in Instagram settings).
• A Valid access_token: For your own account, the easiest way is to get a user-level token by authorizing your app with your Facebook page (since Business/Creator accounts link to a Facebook page). You’ll need the pages_show_list and instagram_basic permissions during authorization.

2. Core API Calls to Fetch Your Data #

Let’s break this down into two parts: getting account info, then pulling post details.

Step 1: Grab the Instagram Business Account ID #

First, you need the unique ID of your Instagram Business/Creator account. You can get this by querying your linked Facebook Page ID:

GET /{your-facebook-page-id}?fields=instagram_business_account

This will return the instagram_business_account object with its id—jot that down, you’ll use it for all subsequent calls.

Step 2: Get Basic Account Info (Username) #

Use the ID from the last step to fetch your account’s username:

GET /{instagram-business-account-id}?fields=username,name

The response will include username (the handle people use to find you) and name (your display name on Instagram).

Step 3: Fetch Post Details (Likes, Date, Image URL, Caption) #

To get all your posts along with the data you need, use this endpoint:

GET /{instagram-business-account-id}/media?fields=id,caption,timestamp,like_count,media_url

Each post in the response will have exactly what you’re looking for:

• caption: The post’s description text
• timestamp: The date/time the post was published (in ISO 8601 format, e.g., 2024-05-20T14:22:00+0000)
• like_count: Total number of likes on the post
• media_url: Direct URL to the post’s image (or video)
• id: The post’s unique ID, useful if you want to fetch a single post later

If you need details for a specific post, just use its ID:

GET /{specific-post-id}?fields=id,caption,timestamp,like_count,media_url

3. Key Things to Keep in Mind #

• Permissions Check: Make sure your access_token has the instagram_basic and pages_show_list permissions. You can verify your token with this call:

  GET /debug_token?input_token={your-access-token}&access_token={your-app-id}|{your-app-secret}
  

• Rate Limits: Graph API has rate limits to prevent abuse. If you’re testing, keep calls spaced out—you’ll get an error if you hit the limit.
• Personal Account Restriction: I can’t stress this enough—regular personal Instagram accounts won’t work with Graph API. You must switch to Business or Creator.

4. Quick Troubleshooting #

I’m not getting any data back. What’s wrong?

• Double-check that your Instagram account is linked to a Facebook Page, and that you’re using the correct Page ID in your initial call.
• Verify your access_token is valid and has the required permissions.
• Ensure you’re using the Instagram Business Account ID (not the Facebook Page ID or regular Instagram user ID) in your media calls.
