Instagram is where the question gets asked and WhatsApp is where the sale gets closed. Running them in two different tabs is how both get dropped.
Instagram DM automation is software that replies to and routes Instagram direct messages automatically using Meta's Instagram Messaging API — so comments, story replies and DMs get an instant answer and reach a human without anyone watching the app all day.
Most tools treat Instagram as a bolt-on. ConvoFly treats it as one of three channels in a single shared inbox — WhatsApp, Instagram DMs and Facebook Messenger — so a customer who asks about a product on Instagram and follows up on WhatsApp is one conversation to your team, not two strangers.
This is the most important thing to understand before you plan an Instagram strategy, and most vendor pages skip it.
Meta gives you a 24-hour standard messaging window after a customer's last message, on both Instagram and Messenger — see Meta's Instagram messaging documentation. Inside that window you can reply freely. Outside it, Instagram has no equivalent of a WhatsApp template: there is no approved-message mechanism that lets you re-open a cold Instagram conversation the way you can on WhatsApp. Some tags exist for narrow cases, and they require Meta App Review.
The contrast with WhatsApp is the whole point. There, an approved template legitimately re-opens a conversation weeks later — see Meta's template documentation. On Instagram there is no such object to approve.
The practical consequence: Instagram is excellent for capture and terrible for follow-up. Treat a DM as a lead with a 24-hour clock on it. The flows worth building are the ones that answer fast and, where the customer agrees, continue the relationship on WhatsApp — where an approved template legitimately lets you message them next week about their order.
The three channels share the same inbox, the same contact record, the same tags and the same flow builder in ConvoFly. That means one automation can be written once and applied to whichever channels you choose, and an agent works a single queue instead of three.
What differs is what each channel permits. WhatsApp lets you re-open a conversation with an approved template; Instagram and Messenger do not. Media handling differs too — attachments on Instagram and Messenger are fetched by Meta from a link, which ConvoFly handles for you. Plan your follow-up strategy around WhatsApp, and use Instagram for what it is genuinely good at: volume at the top of the funnel.
This is the whole game on Instagram, so it is worth spelling out. Inside the 24-hour window you can say anything. Outside it you can say nothing. So the flow that matters is the one that converts a transient DM into a durable contact before the clock runs out.
The mechanics are simple. Answer the question first — nobody opts in to a business that has not helped them yet. Then offer a concrete reason to continue on WhatsApp: order updates, a stock alert, a delivery notification. Capture the opt-in explicitly and record it, because WhatsApp's opt-in rules require consent you can evidence, not consent you assume. Save the answer to a contact attribute so later flows can branch on it.
If you run click-to-WhatsApp ads, the same logic runs in reverse and more cheaply: the ad opens a WhatsApp conversation directly, so the opt-in and the 24-hour window start on the channel you actually want them on.
The builder is the same and the thinking is not. On WhatsApp you design for a relationship you can resume — templates let you come back next week about an order. On Instagram you design for a single session with a hard 24-hour edge, so every flow should aim to resolve the question or capture the customer inside that session.
The second difference is volume and noise. Instagram DMs skew toward browsing rather than buying: more questions, lower intent per message, and more people who will never purchase. Qualification matters more here, and it is worth letting automation carry more of the early conversation than you would on WhatsApp.
Instagram conversations go wrong faster than WhatsApp ones, because the audience is browsing rather than transacting and their patience is shorter. Three signals should hand the chat to a person immediately: a complaint, a repeated question the bot has already failed once, and any message containing a specific order or payment detail.
Handoff should be a first-class step in the flow rather than a fallback, and the agent needs to see the whole transcript when they arrive — handing a chat from bot to human covers how to wire it so nothing is repeated back to the customer. Because all three Meta channels share one inbox, the agent picking up an Instagram DM works in exactly the same place as your WhatsApp team.
Planning a broadcast strategy. There isn't one. If your plan depends on messaging past Instagram contacts, the plan does not survive contact with Meta's rules.
Letting the bot run the whole conversation. Instagram customers disengage fast. Hand off early, especially on anything that sounds like a complaint.
Ignoring the clock. A DM that arrives on Friday evening and gets answered Monday is outside the window and cannot be answered at all. Business-hours flows should acknowledge immediately even when no one is there.
Instagram is included from the $12/month Starter plan, which covers one channel — WhatsApp, Instagram or Messenger, your choice. Running all three at once starts on Growth at $50/month, which also unlocks the AI knowledge-base bot and Copilot. Every plan includes a 14-day free trial.

You can find tools that do it unofficially, and they put your account at risk of restriction or loss. ConvoFly uses Meta's official Instagram Messaging API, which requires a professional account linked to a Facebook Page and keeps your account in good standing.
No. Unlike WhatsApp, Instagram has no approved-template mechanism for re-opening conversations, so there is no compliant way to run a broadcast campaign to past Instagram contacts. Use Instagram to capture and answer, and WhatsApp for opt-in follow-up.
Meta's API supports replying to a comment by opening a DM in some cases, but the reliable pattern is to answer the comment publicly and invite the person to message you. Once they DM, your 24-hour window opens and your flows take over.
No. Meta does not charge per conversation on Instagram or Messenger the way it does on WhatsApp, so the only cost is your ConvoFly plan. Starter at $12/month covers one channel; running WhatsApp, Instagram and Messenger together starts at $50/month.
Yes. All three Meta channels arrive in one shared inbox with shared contacts, tags and assignment. An agent works a single queue, and a customer who moves from Instagram to WhatsApp keeps their history.
