# Viber Channel

A **Viber Channel** is a broadcast feed: you post, members read. Voice Logica can post to your channel when you ask, and automatically from a workflow, for example a short summary after every call.

A channel is **one-way**. Members cannot chat with your agent there. For customer conversations, connect a [Viber bot](https://docs.voicelogica.ai/agent-configuration/viber/) instead.

| | Viber bot | Viber Channel |
|---|---|---|
| What it is | A private chat between each customer and your agent | A feed: you post, members read |
| The agent answers | Yes | No |
| Where the token comes from | [partners.viber.com](https://partners.viber.com) | The Viber app: channel → Info → **Developer Tools** |
| Good for | Customer questions, orders, photos | News, offers, closures, alerts to your team |

## Connect a channel

1. **Create the channel** - in the Viber app (version 17.7 or newer): **Chats** → pencil icon → **Create Channel**. Choose **private** (invite link only) for alerts to your team, **public** for announcements to customers.

2. **Copy the channel token** - only the channel's **superadmin**, the person who created it, can see the token. On their phone: open the channel → tap its name → **Developer Tools** → copy the token.
   - No **Developer Tools**? Update Viber, and check you are signed in as the superadmin. Admins who are not superadmins do not see it.

3. **Connect it** - in Voice Logica open **Integrations** → **Channels**. On the **Viber Channels** card press **Connect channel**, paste the token and press **Connect channel**. Voice Logica checks the token with Viber and turns on posting.

<Aside type="caution">
Treat the token like a password: anyone who has it can post to your channel. If it leaks, disconnect the channel and ask Viber support (devsupport@viber.com) for a new token.
</Aside>

## Post a message

1. On the **Viber Channels** card press **Post** next to the channel.

2. Write the message (up to 7,000 characters). To add a picture or a file, press **Attach picture or file**:
   - **Photos** are converted to a JPEG under 1 MB, Viber's limit, and posted with your message as the caption (or before it, when the message is longer than 512 characters).
   - **Other files**, such as a PDF price list, up to 50 MB, are posted right after the message.

3. Press **Preview**. Voice Logica shows how many members will see the post.

4. Press **Post now**. The post appears in the channel under the channel's name.

You can also ask Claude or ChatGPT, for example "post on our Viber channel: we are closed on Monday". It shows you the channel and its member count first, and posts only after you confirm.

## Send call alerts to the channel

The simplest way: open the agent → **Notifications** → **Viber Channel**.

1. Turn on **Viber Channel**.
2. In **When to send**, choose **Always**, or let the AI decide and describe when, for example "only if the caller wants a quote".
3. In **Channels**, pick your team's **private** channel. No channels listed? Connect one first in **Integrations** → **Channels**.
4. Leave **Message** empty to post the call summary, or write your own with variables. Set a **Minimum duration** to skip very short calls.
5. Save, make a test call and check the channel.

For more control, for example different messages per outcome, a workflow can post to the channel instead:

1. Create a **private** channel with only your team in it, and connect it as above.

2. In a workflow that runs [on call end](https://docs.voicelogica.ai/workflows/on-call-end/), add a [Send Viber](https://docs.voicelogica.ai/workflow-nodes/send-viber/) node. Set **Send To** to your channel and write the message from the call, for example `New call from {{call.phone_number}}: {{call.summary}}`.

3. Make a test call and check that the alert arrives in the channel.

Claude or ChatGPT can also set it up: ask it to "post a summary of every call to our Viber channel".

<Aside type="danger">
Every member of a channel sees every post. Never send customer details, such as names, phone numbers or call summaries, to a **public** channel.
</Aside>

## Disconnect

On the **Viber Channels** card press **×** next to the channel. Nothing more is posted to it. Workflow alerts that still post there fail until you change or remove them.

## From Claude or ChatGPT

`get_guide` (guide `"post_to_viber_channel"`) walks through these steps. `channels_execute` connects (`connect_viber_channel`), posts (`post_viber_channel`) and disconnects (`disconnect_viber_channel`), and `channels_query` with `list_channels` shows the connected channels under `viberChannels`.

## Frequently asked questions

**What is the difference between a Viber Channel and a Viber bot in Voice Logica?**
A Viber Channel is a one-way feed: you post, members read, and members cannot chat with your agent there. A [Viber bot](https://docs.voicelogica.ai/agent-configuration/viber/) is a private chat between each customer and your agent, where the agent answers. Use a channel for news, offers, closures and alerts to your team, and a bot for customer questions, orders and photos.

**Where do I find the token of my Viber Channel?**
Only the channel's superadmin, the person who created it, can see the token. On their phone, in Viber 17.7 or newer: open the channel → tap its name → **Developer Tools** → copy the token. If **Developer Tools** is missing, update Viber and check you are signed in as the superadmin.

**How do I post a summary of every call to my Viber Channel?**
Open the agent → **Notifications** → **Viber Channel**, turn it on, choose **Always** in **When to send** (or describe when the AI should send), and pick your team's private channel. Leave **Message** empty to post the call summary, then save and make a test call. For different messages per outcome, use a workflow that runs on call end with a [Send Viber](https://docs.voicelogica.ai/workflow-nodes/send-viber/) node instead.

**Can I send call details to a public Viber Channel?**
No. Never send customer details such as names, phone numbers or call summaries to a public channel, because every member of a channel sees every post. For call alerts, use a private channel with only your team in it.

**Can I post photos or a PDF to my Viber Channel from Voice Logica?**
Yes. On the **Viber Channels** card press **Post**, write the message (up to 7,000 characters) and press **Attach picture or file**. Photos are converted to a JPEG under 1 MB, Viber's limit, and other files such as a PDF price list, up to 50 MB, are posted right after the message.

**What do I do if my Viber Channel token leaks?**
Anyone who has the token can post to your channel. Disconnect the channel in Voice Logica (press **×** next to it on the **Viber Channels** card) and ask Viber support at devsupport@viber.com for a new token.
