How it works
From a comment to a click you can see.
Postbooster listens for one word on the posts you choose, answers in DMs with exactly what was asked for, and keeps track of what happened next. Here’s the whole thing, in five moments.
- 1 · Comment
Someone comments your keyword
You pick the post and the word — TOUR, PLAN, TICKETS. Matching is forgiving: capitals, punctuation, close spellings and the variants you add all count. Everything else is ignored.
Webhook from Meta’s official API
- 2 · Public reply
A short reply under their comment
Optional, and in your words: “Sent it to your DMs!” It tells the commenter to check their inbox and shows everyone else that commenting works.

- 3 · DM
The link arrives in their DMs
A private reply with a button, or a carousel of cards — brochure, booking page, file, presale. Want a follow first? Turn on follow to unlock.
Button or carousel
- 4 · Click
Every click is tracked
Links are wrapped so Postbooster knows who clicked what, from which post, keyword, message variant and link — then forwards them straight to your page.
Post → trigger → funnel → variant → link

You follow up with the right people
A nudge for people who didn’t click, where Instagram’s messaging window allows. Replies land in the inbox, and the attention list shows who’s worth a personal message.

Questions
The rules, plainly.
Is this allowed by Instagram?
Yes. Postbooster uses Meta’s official Instagram API through Business Login for Instagram. It only messages people who commented on your post or messaged you first, and works inside Instagram’s rules for private replies and the messaging window.
Can Postbooster message my followers or people who didn’t comment?
No. The API doesn’t allow cold messages, and we wouldn’t build it if it did. Everyone Postbooster messages asked for it by commenting or writing to you.
Does it post or schedule content for me?
No. Postbooster works on posts you’ve already published. It doesn’t publish, like, follow or comment on your behalf beyond the replies you set up.
How do I test a flow before it goes live?
During setup you name a second Instagram account — a personal one or a friend’s — and comment the keyword from it. Instagram never triggers automations on your own comments. The DM arrives for real, and those interactions are marked as tests, so your numbers stay clean.

Pick a post, choose a keyword, and watch the first comment turn into a DM and a tracked click.
