Channels

Connect Facebook Messenger, Instagram DM, WhatsApp Business and Website Chat

Step-by-step connection, testing and troubleshooting for all four messaging channels.

10 min read

All channels are connected from Integrations in your workspace. Only Owners and Admins can connect or disconnect them. Techno AI never shows access tokens or secrets on screen, and you should never share them with anyone.

Note:The status badge on each card tells you where you are: Not connected, Connected, Error, Needs Meta App (the platform administrator hasn't configured Meta yet) or Not available (not in your plan).

1. Facebook Messenger

Before you start

  • You must be an admin of the Facebook Page you want to connect.
  • Your plan must include Facebook.

Connect

  1. Open Integrations and find Facebook Messenger.
  2. Choose Connect Facebook (it may say Connect Facebook Business).
  3. Log in to Facebook, select your Page and approve the requested permissions (Page messaging).
  4. Back in Techno AI, pick the Page in Select Facebook Page and choose Connect.

Check it works

  1. From a different personal Facebook account, send your Page a message.
  2. Open Inbox — the chat should appear with the channel name, and your Live AI agent replies.

Common problems

  • Error badge: open Manage to read the last error, then use Reconnect.
  • No messages arrive: make sure you are messaging from an account that does not manage the Page.
  • Page comments: comments are used only for automatic comment replies and do not appear in the Inbox.

2. Instagram Direct Messages

Before you start

  • The Instagram account must be a professional (Business or Creator) account.
  • It must be linked to a Facebook Page that you manage.
  • In the Instagram app, turn on Allow access to messages (Settings → Messages and story replies → Message controls → Connected tools).

Connect

  1. In Integrations, find Instagram Messaging and choose Connect Instagram.
  2. Approve the Instagram messaging permission in the Meta window.
  3. Select the Instagram account and choose Connect. The card then shows the account and its linked Page.

Check it works

  1. Send a DM from a different personal Instagram account.
  2. Check the Inbox. Messages sent as message *requests* may need to be accepted in Instagram first.

Common problems

  • Messages don't arrive: Meta only sends DMs when the account is linked to the Page and message access is on. Meta's own review of the messaging permission can also limit delivery.
Important:Known issue — Instagram DMs for the Techno Power Bangladesh account are currently not reaching Techno AI. Meta is not sending these messages to us at all. Facebook Page messages for the same business still arrive. We are investigating with a read-only check of Meta's records.

3. WhatsApp Business

Before you start

  • You need a WhatsApp Business Account and a phone number you control.
  • Your plan must include WhatsApp.

Connect

  1. In Integrations, choose Connect WhatsApp and complete Meta's signup window.
  2. Select your phone number and choose Connect.
  3. If you already use the WhatsApp Business app on that number, use the WhatsApp coexistence card on the same page. It uses Meta's official signup, so you keep using the app.
  4. Open Manage to see your numbers, choose which one sends new chats, and pick the AI Agent for WhatsApp.

Check it works

  1. Send a WhatsApp message to the connected number from another phone.
  2. It appears in the Inbox and the agent replies from the same number.

Common problems

  • No production number connected: reconnect and share your WhatsApp Business Account in the Meta window.
  • Warning badge on a connected card: read the message under the card; it explains what Meta reported.

4. Website Chat

Set up

  1. Open Integrations → Website Chat → Set up (or open Website Chat from the menu).
  2. Change the Widget settings — for example the position (Bottom right or Bottom left) — and check the Preview.
  3. Under Installation code, choose Copy code.
  4. Paste the code into your website just before the closing body tag, on every page where the chat should appear.

Check it works

  1. Open your website in a private browser window and send a message in the chat bubble.
  2. The conversation appears in the Inbox as Website Chat and the AI replies in the widget.

Common problems

  • The bubble doesn't show: make sure the code is on the published page and not blocked by a cache or a content-security setting.
  • No AI reply: check that you have a Live AI agent.
