What it does

You save time on manual Instagram DMs by automatically scanning conversations every 15 minutes for specific keywords. When a match occurs, the agent instantly replies with your relevant affiliate links using the Meta Graph API. This ensures you never miss an opportunity to engage interested buyers while avoiding duplicate responses through ID logging.

Watch out for

Instagram enforces strict spam detection so you must add random delays between replies to avoid account suspension.
The Graph API requires specific permissions like pages_manage_messaging which can take days to approve for new apps.
Affiliate links may be flagged as spam by Instagram if they are not shortened or hosted on trusted domains.
Message threading IDs change frequently so your code must robustly parse the latest thread_id from each webhook payload.
