How to publish and automate an Instagram post in one flow
By Michał Kołnierzak · Updated November 7, 2026
Publishing a post and setting up its automation are often two separate jobs in two separate tools. This playbook shows how to do both in a single flow with CommentTap: create the post, publish it through Instagram's official Content Publishing API, add an automatic first comment, and attach a comment-to-DM campaign so people who comment your keyword get an automatic reply from the start.

What this guide covers
Can you create the Instagram post inside CommentTap?
Start by choosing what to publish — a photo, a Reel or a carousel — and upload the media directly in CommentTap. Write a caption that clearly invites people to comment a specific keyword, such as ‘guide’ or ‘link’, or generate one with AI and edit it to sound like you. Because the post is created here rather than in the Instagram app, everything you need for the automation lives in the same place.
Can you publish now or schedule for later?
Decide whether the post should go out immediately or at a planned time. Publishing now sends it straight through the official API; scheduling queues it so it publishes automatically when your slot arrives. Either way you can add an automatic first comment that carries an extra call to action or link, which is a good place to remind followers which keyword to type.
How do you attach a comment-to-DM campaign to the post?
Before the post is live, connect the keyword, the message and the offer you want to deliver — a link, a PDF, a coupon or a booking page. The campaign is wired to the post on publish, so there is no second setup step and no window where comments arrive with nothing to answer them. From the first matching comment onward, CommentTap sends each person an automatic direct message, within Instagram’s limits.
How do you measure what the post produced?
Once the post is live, watch the funnel from comments to DMs to clicks and captured leads. Seeing which post and which keyword drove real results tells you what to publish next, so each launch informs the next one.
Key takeaways
- Publishing and automating in one flow means the campaign is ready when the post goes live.
- An automatic first comment is a good place to repeat your keyword.
- Scheduling lets a post publish and start capturing leads on its own.

FAQ
Questions, answered
- Do I need the Instagram app to publish the post?
- No. CommentTap publishes photos, Reels and carousels directly through Instagram's official Content Publishing API, so you can create and launch the post without opening the app.
- When does the automation start working?
- The comment-to-DM campaign is attached before the post publishes, so automatic replies begin from the first person who comments your keyword once the post is live.
- Can I plan a whole content calendar this way?
- Yes. On plans that support scheduling you can prepare each post, its first comment and its campaign ahead of time and let them publish automatically on the dates you choose.
