What is automated for Messenger today
- Every message sent to your Facebook Page arrives in the Chatzyn inbox, next to your WhatsApp and Instagram chats, with no copying between apps.
- New Messenger chats are assigned to an agent by the same auto-assignment rules you set for your other channels, including agent capacity.
- When a customer sends a photo, video or file, the thread shows that they sent one. Viewing Messenger attachments inside Chatzyn is not available yet.
- The inbox tracks Meta's reply windows for you and blocks a reply Meta would refuse, so agents do not find out after sending.
What does not work on Messenger yet
Be clear about this before you buy. Chatzyn's flow builder, keyword triggers, welcome and away messages, the AI bot and template broadcasts run on WhatsApp, and the flow builder also runs on Instagram. None of them send on Messenger today.
Agent replies on Messenger are text only, up to 2,000 characters. Messenger rejects a longer message rather than sending part of it, so the composer counts characters for you.
If you need an instant automatic reply on your Page right now, use the automated responses in Meta's own Business Suite for that, and let your team handle the conversation in Chatzyn.
Meta's Messenger rules: the 24-hour window and human agent replies
In Chatzyn, you reply to people who have messaged your Page. When a person writes to your Page, you have 24 hours to reply, and every new message from them opens a fresh 24 hours.
After that, Meta allows a reply typed by a real person for up to 7 days, for support that could not be finished in time, such as a weekend closure. Automated content is not allowed in that extra time.
Chatzyn follows these rules in the inbox. It never sends a cold message to someone who has not written to your Page, and outside the 24 hours it only sends a reply a person typed.
Rules checked against Meta's Messenger Platform documentation on 29 Oct 2026.

One inbox for Messenger, WhatsApp and Instagram
Most small businesses get the same customer on more than one app. In Chatzyn a contact can hold a WhatsApp, an Instagram and a Messenger identity together, so your team sees the whole history in one place.
Admins can restrict a Facebook Page to named users, the same way they restrict a WhatsApp number or an Instagram account. Agents who are not on the list do not see that Page's chats.
Connect your Facebook Page in about three minutes
- You need an active plan or the free trial, and admin access to the Facebook Page.
- In Chatzyn, open Settings, Channels and expand Facebook Page.

Questions people ask
Can Chatzyn send an automatic reply on Facebook Messenger?
Not yet. Today Chatzyn brings Messenger chats into the shared inbox and assigns them to agents automatically. Welcome messages, keyword replies, flows and the AI bot run on WhatsApp, and flows also on Instagram, but not on Messenger.
How do I set up a Messenger auto reply for my business Page?
Meta Business Suite has its own automated responses for Pages. You can use those for an instant reply and still answer the conversation from Chatzyn's inbox with your team.
How long can a business reply to a Messenger message?
24 hours from the customer's last message. After that, Meta allows a reply typed by a person for up to 7 days for support that could not be finished in time. Automated messages are not allowed in that extra time.
Can I send bulk messages or broadcasts on Messenger?
Not from Chatzyn. On Messenger, Chatzyn only replies to people who have written to your Page, and it does not send cold or bulk messages on Messenger. For opt-in marketing to many customers, use WhatsApp templates.
Can my whole team reply to Facebook Page messages?
Yes. Messenger chats land in the same shared inbox as WhatsApp and Instagram, are auto-assigned to agents, and admins can limit a Page to named users.
Can I send photos or files on Messenger from Chatzyn?
Not yet. Chatzyn shows when a customer sends a photo, video or file, but you cannot open Messenger attachments in Chatzyn yet. Replies from Chatzyn on Messenger are text only for now, up to 2,000 characters.
Is Chatzyn using the official Messenger API?
Yes. Chatzyn connects your Page through Meta's official Messenger Platform with Facebook login. It does not use your personal Facebook password or any unofficial tool.
