Facebook Messenger Bot
Customer comments 'price?' on your Reel. You see it 4 hours later, they're already gone. A Mingleego bot would have sent them the price plus a checkout link in their DMs while they were still scrolling.
From a Page to a Messenger bot in four clicks
Have a Facebook Business Page
If you already manage one, you're done with step 1. If not, facebook.com/pages takes about 5 minutes — and Pages are free.
OAuth into Mingleego
Click 'Connect Facebook' in the dashboard, log in, grant page-message permissions. No Meta Developer App, no access tokens to copy and paste, no developer console.
Upload what the bot should know
Catalog, FAQs, pricing pages, policies — PDFs, CSVs, JSON, TXT, up to 500MB. Write the bot's voice in plain language.
Turn on comment-to-DM
Enable the comment-to-DM rules so when someone comments on your post or Reel, the bot answers publicly and follows up in DMs with full info. That's where the leads come from.
The lead-gen leak on every Facebook Page
Reels and posts get 'price?' comments — you reply hours later
By the time your social manager replies, the customer's scrolled to a competitor. The interest window on Facebook is measured in minutes, not hours.
Page DMs scatter across three different surfaces
Meta Inbox, Pages Manager, and Business Suite all show different views. Your team checks one, misses the others.
Setting up Messenger usually means a Facebook Developer App
Most platforms require you to spin up a Facebook Developer App, configure OAuth scopes, and copy permanent tokens. That's a lot of moving parts for one channel.
Comment-to-DM is locked behind a Meta partnership
The highest-converting Facebook funnel — public reply plus DM follow-up — isn't available to every chatbot. You need explicit Meta partnership access.
How Mingleego Facebook bots actually work
Connect your Facebook Business Page to Mingleego in one OAuth click — no Meta Developer App, no manual tokens. The bot replies to inbound Page DMs using AI trained on your real business data, and via our Meta partnership it can also auto-reply to comments and follow up in DMs (the lead-gen pattern that justifies the whole channel). Upload your training files (PDFs, CSVs, JSON, TXT up to 500MB), pick a model — anything from the small GPT-4.1 Mini to the latest GPT-6.1 Sol — and the bot answers. Same assistant later runs on Instagram, WhatsApp, Telegram, Discord, Slack, and your website chat.
Six patterns that actually convert
Comment-to-DM funnel
Customer comments 'price?' or 'link?' on your post — bot replies in their DMs with product info, photos, and a checkout link. The classic high-converting Facebook play, fully automated.
Catalog browsing inside the DM
Customer says 'something around $40, in red' — bot searches your Shopify or eBay inventory and answers with images, prices, and availability.
Send a photo, get a sizing answer
Customer photos a product or screenshot. Vision reads the image and the bot answers — compatibility, sizing, what's in stock right now.
Book demos and consultations
Bot offers slots from Google Calendar or Outlook Calendar, books the meeting, the event lands on your calendar with invites. No back-and-forth.
Order status without a ticket
Pulls live status from Shopify or eBay so 'where's my order?' is answered in seconds — not after a support queue.
Forward a receipt or PDF in chat
Customer drops a PDF (receipt, contract, spec sheet) into Messenger. Bot reads it and answers questions about it without making the customer paraphrase.
What you get on Facebook specifically
1-click Page OAuth
Connect your Facebook Business Page via OAuth in seconds. We handle the Meta API config under the hood — you handle the marketing.
Comment-to-DM via our Meta partnership
Auto-reply to comments on your posts and follow up in DMs with full info. The single highest-converting Facebook lead-gen pattern, enabled by Mingleego's partnership with Meta. Plus quick-reply buttons, persistent menu, and rich cards where appropriate.
RAG with citations
Bot answers from your real catalog, FAQs, and pricing — and shows which file each answer came from. No hallucinated prices.
Vision and inbound files
Customers can send photos and PDFs in Messenger. The bot reads them and replies in context — with images, documents, or location pins of its own.
20+ GPT models, your call
GPT-4.1 through GPT-6.1 Sol, including the lightweight Nano variants. Pick per assistant — small models for high-volume FAQs, bigger models for sales conversations.
Connect your stack
Shopify, eBay, HubSpot CRM, Outlook (email + calendar), Google Calendar. Email Notification add-on sends a chat transcript after each conversation if you want it.
Facebook Messenger bot questions
No. You connect your Page via OAuth in one click — log in to Facebook, grant page-message permissions, done. No Developer App to create, no access tokens to copy, no developer console to learn.
The comments are already coming in
