What are Instagram webhooks?
Instagram webhooks are real-time notifications Meta sends to an app when something happens on a connected account, such as a new comment, DM, story mention or message reaction.
Detailed Explanation
Webhooks are how automation reacts within seconds. Instead of asking Instagram "any new comments?" every minute, the app registers a callback URL, and Meta pushes each event to it as it happens. The app verifies the event signature, decides which rule applies and responds through the API. Reliable tools queue events so that a viral post with thousands of comments is processed safely.
How It Works Step-by-Step
The app subscribes to fields such as comments, messages and mentions.
Meta sends an HTTPS request to the app’s callback URL for each event.
The app checks the signature to confirm the event really came from Meta.
The event is queued, matched to rules and answered through the API.
How Teams Use This in Production
"A reel gets 2,000 comments in an hour. Each comment arrives as a webhook, enters a queue and is answered in order without overloading the API."
Why It Matters for Growth & Revenue
Webhooks make instant replies possible and avoid wasteful polling, which can hit rate limits.
