A user messages 'PRICE' on your Facebook Page — your bot sends a product catalog with images, prices, and 'Shop Now' buttons that deep-link to your store.
Event & Webinar Registration
Pin a post saying 'Comment FREE to get the link.' ReplyKaro sends the webinar link via Messenger to every commenter, instantly adding them as subscribers.

Facebook Messenger Bot — FAQ
What is a Facebook Messenger bot?
A Facebook Messenger bot is an automated system that sends and receives messages on your Facebook Page via the official Messenger Platform API. When a user sends your Page a message containing a keyword (e.g. 'PRICE', 'BOOK', 'DEMO'), the bot instantly sends back your preset reply — without any manual effort. ReplyKaro's Messenger bot supports keyword triggers, multi-step conversation flows, button responses, and lead capture.
How do I build a Facebook Messenger bot without coding?
With ReplyKaro, you don't need to write any code. Connect your Facebook Page, create an automation with your trigger keyword, write your Messenger reply (text, buttons, images, or a multi-step flow), and go live. The whole setup takes under 5 minutes. ReplyKaro's visual flow builder lets you create branching conversations with no coding required.
Is there a free Facebook Messenger bot tool?
Yes. ReplyKaro's Free Forever plan includes Facebook Messenger keyword automation with 1,000 DMs/month at no cost. No credit card required, no contact cap. Paid plans start at ₹99/mo ($3/mo globally) for 15,000 Messenger DMs/month.
Can a Facebook Messenger bot capture leads?
Yes. When a user messages your Facebook Page and triggers a keyword reply, they are automatically added to your ReplyKaro subscriber list. You can then segment them by behavior and send targeted Messenger broadcast campaigns — achieving 80–95% open rates compared to 20–30% for email.
What's the difference between Facebook Comment-to-DM and Messenger bot?
Facebook Comment-to-DM triggers when someone comments a keyword on your post — it sends them a Messenger DM automatically. A Messenger bot triggers when someone sends your Facebook Page a direct message. ReplyKaro supports both: Comment-to-DM for post engagement, and the Messenger keyword bot for direct inbox automation. Both are included on all plans.
