Use this guide to connect each channel to LynaX, assign an AI Seller, and test both message directions before enabling automation.

Before you connect

Sign in to the correct workspace with channel-management permission.
Create and activate at least one AI Seller.
Open Chat Platform → Connections and choose Connect channel.
Follow the platform-specific procedure below.

Do not enable auto-response immediately. Complete the validation steps at the end first.

Connect Facebook Messenger

Use a Facebook account that administers the target Facebook Page.
Choose Facebook Messenger → Connect now.
Sign in, select the Page, and grant the requested messaging permissions.
Back in LynaX, verify that the connection shows the correct Page name.
Open its menu and run Check connection. Configure public/private comment replies under Settings when needed.

Connect Instagram

Use an Instagram Business Account linked to a Facebook Page.
Connect that Facebook Page to LynaX first.
Choose Instagram → Connect now, sign in through Facebook, and grant access to the linked Instagram account.
Verify the account name in LynaX and run Check connection.

Connect Zalo OA

Use an account that administers the Official Account.
Choose Zalo OA → Connect now, sign in, select the OA, and approve access.
When the connection appears, run Check connection and send a test message from a customer account.
Assign an AI Seller, check the conversation in Seller Hub, and enable automation only after both directions work.

Create Website Chat

Choose Widget Chat → Connect now, name the widget, select an AI Seller, and configure its appearance.
For a LynaX website, select the website in the widget configuration and enable Draft and/or Live. No embed code or website rebuild is needed.
For an external website, enter a bare domain such as example.com, then copy the embed script after creating the widget.
Open the site in a private window, send a test message, and verify it in Seller Hub.

Connect WhatsApp Business

Prepare a Facebook account with access to the Meta Business Portfolio and the phone number intended for WhatsApp Business.
Choose WhatsApp Business → Connect now to open Meta Embedded Signup.
In Meta, select or create the Business Portfolio and WhatsApp Business Account, then select/register the phone number.
Grant the requested permissions and finish the popup without closing it early.
Verify the account/number in LynaX and run Check connection.

“WhatsApp Embedded Signup is not configured” requires a LynaX workspace administrator. If Meta does not return a WABA ID or Phone Number ID, restart signup and complete phone verification.

Connect a Telegram Bot

Open verified @BotFather.
Send /newbot, provide a display name, and choose a username ending in bot.
Copy the Bot Token and keep it secret. See the official Telegram tutorial.
In LynaX choose Telegram → Connect now, paste the Bot Token, and confirm.
LynaX validates the bot and registers its webhook automatically. Run Check connection.
Open the bot from a personal Telegram account, press Start or send /start, then send a test message.

A Telegram Bot cannot initiate a conversation; the customer must message it first. Revoke the token in BotFather and reconnect if the token is exposed.

Connect a LINE Official Account

Create a LINE Official Account and enable Messaging API using the LINE Developers guide.
In LINE Developers Console, open the Messaging API channel and obtain Channel Secret, Channel ID, and a Channel Access Token.
In LynaX choose LINE → Connect now; enter Channel Access Token, Channel Secret, and optionally Channel ID.
Confirm. LynaX validates the bot and registers the webhook endpoint.
Add the Official Account as a friend, send a test message, and run Check connection.

Review LINE's Channel Access Token guidance and revoke a token if exposure is suspected.

Assign a Seller and activate

Choose Manage AI Sellers on the connection.
Assign one or more active Sellers.
Send a customer-side test and verify the conversation in Seller Hub.
Send one manual reply to validate outbound delivery.
Enable Auto-response. Enable Data collection only after a collection/view is assigned to the Seller.

Troubleshooting

No incoming messages: run Check connection, confirm the correct Page/OA/number, and send a customer-side test message.
Outbound delivery fails: check the messaging window, provider permissions, and the Page/OA/number state.
Auto-response cannot be enabled: assign an active AI Seller first.
OAuth or token expired: reconnect; issue a new Telegram/LINE token if the previous token was revoked.
Duplicate replies: disable provider auto-replies or another tool using the same channel.

Proactive messages, messaging windows, templates, and supported file types are governed by each provider. A connected state does not replace provider approval.
