We are a medical aesthetics practice running application-based model call programs where prospective clients comment a specific keyword on a post to apply for discounted treatment. When someone comments the trigger word we need Instagram to instantly DM them a short message and a link to a pre-screening application form hosted outside of ManyChat.

The core flow is:

1. We post a model call on Instagram with a CTA telling followers to comment a specific word to apply
2. Someone comments that word on the post
3. ManyChat instantly fires a DM to that commenter with a brief branded message and a form link
4. The commenter fills out the application form
5. We review applications and approve or decline manually
6. Approved applicants receive a booking link separately

This is distinct from a standard broadcast or newsletter flow. It is a one-to-one triggered response to a public comment that initiates a private screening conversation. The trigger word is campaign-specific so we need to be able to set a unique keyword per post and update it each time we run a new model call or promotional campaign.

This use case is extremely common in the medical aesthetics, medspa, and beauty industry where practices are legally required to screen clients before booking certain treatments. A seamless comment-to-application flow removes friction for the client while giving the practice the screening step required before any appointment is confirmed.
