Instagram Comment DM Automation

I’m ready to boost my marketing campaigns by automatically turning every public interaction on Instagram into a direct, personalised message. Using Meta’s Graph and Messaging APIs, I want a server-side solution that listens for new comments on my Instagram posts, stories, and reels, then instantly replies in the user’s DM with a preset or dynamically generated message.

Here’s what the finished job should give me:
• A working webhook that receives Instagram comment events for posts, stories, and reels.
• Code (Node.js, Python, or another common language) that calls the Instagram Messaging API to send a DM to the commenter.
• Clear setup instructions covering Meta app permissions, long-lived access tokens, and any required Instagram account settings.
• Testing proof (screenshots or short video) showing a live comment triggering the correct DM.

Keep the code clean, well-documented, and easy for me to update with new campaign copy later.
