Verifies the comment is on a specific promotional post (and ignores your own replies).\n3. Checks if the commenter typed the exact trigger keyword.\n4. Automatically sends a direct message to the user with the requested document or link.\n\n### \u26a0\ufe0f CRITICAL SETUP STEPS \u26a0\ufe0f\n\n- [ ] **Webhook:** Connect your Meta Developer App and subscribe to Instagram `comments`.\n- [ ] **Target Post:** Open the `Match Post ID` node. Paste your **Instagram Post ID** and your **Instagram Account ID** to prevent self-looping.\n- [ ] **Trigger Word:** Open the `Match Comment Text` node. Set your exact trigger words (e.g., \"DM\", \"Send it\").\n- [ ] **The Message:** Open the `Data` node. Replace \"Your-Message-Here\" with your custom message and link!\n- [ ] **Auth:** Add your Graph API credentials in the `Send DM` node."
