How to Auto-Post RSS to Viber Channels (2026)

Updated: 2026-09-28

Short answer: open your Viber Channel as super admin, go to Developer Tools and copy the channel's authentication token. In PostRSS, open Accounts → Add new Viber account and paste it, then open Tikslai → Add feed, choose Viber in Target settings and add your feed under Add source (Type = RSS feed, Link = your feed address). Each new item is posted to the channel as a picture with the title and link, or as text with the link when the article has no JPEG image. Viber is included from the Professional plan.

Viber is one of those networks that barely registers in English-language marketing advice and matters enormously in practice. In Ukraine, Belarus, much of the Balkans, Greece, the Middle East and parts of South-East Asia it is a primary messaging app, and Viber Channels are the broadcast format inside it — a publisher posts, subscribers receive. If you sell into those markets, a Channel is often closer to your customers than any social timeline.

What a Viber Channel is, and why it suits a feed

A Channel is a one-to-many broadcast space. Subscribers follow it, the admins post, and there is no algorithm deciding who sees what — the message reaches the people who opted in. That makes it behave much more like an email list than like a social feed, and it makes it a natural fit for an RSS feed: every new article on your site becomes one message to an audience that asked for it.

The trade-off is the same as with any broadcast channel. Because there is no ranking to hide behind, volume is visible. A channel that posts fifteen times a day gets muted; one that posts when there is genuinely something new does not.

Setting it up, step by step

1. In Viber, open the channel info as super admin, go to Developer Tools and copy the authentication token. Nothing else needs registering — there is no developer account, no app review and no approval queue.
2. In PostRSS, open Accounts and choose Add new Viber account. Paste the channel token. That single value is the credential, so treat it the way you would a password.
3. Open Targets and click Add feed. One feed going to one destination is one Target.
4. In Target settings, choose Viber and the account you just connected.
5. Click Add source. Set Type to RSS feed and paste your feed address into Link. Save.
6. Check the first item that arrives. PostRSS checks the feed every 5 minutes (every minute on Enterprise plans), so the wait is short.

What subscribers actually see

PostRSS adapts the message to what the feed item carries. When the article has a JPEG image, the item is posted as a picture post with the title and the link, which is what you want for anything visual — a product, a recipe, a property listing, an event. When there is no JPEG, it goes out as text with the link instead, which still reads cleanly in the channel.

That behaviour is worth knowing before you connect anything, because it means the quality of your feed decides the quality of the post. A feed that ships a proper featured image gets picture posts; one that does not gets text. No automation can invent a photograph.

Who this actually helps

• Retailers in Eastern Europe and the Balkans. New-arrival and promotion posts reach subscribers directly, without competing with a ranking algorithm.
• Local news and community sites. Viber Channels function as a news wire in several markets where they have effectively replaced SMS alerts.
• Service businesses with a blog. Clinics, law firms, driving schools: the blog exists anyway, and the channel turns it into something subscribers see.
• Anyone already maintaining a Telegram channel. The same feed can go to both. In several countries the audiences barely overlap.

What it does not do

PostRSS publishes items that appear in the feed after the Target starts running. Connecting an established feed does not import its back catalogue, which is deliberate — the alternative is a destination flooded with years of archive on day one.

It also does not manage subscribers, moderate replies or schedule around quiet hours. PostRSS puts new items into the channel; everything else about running the channel stays in Viber.

Which plan includes it

Viber is included from the Professional plan. Each destination you connect counts as one Target, and your plan sets how many Targets and how many posts a month you get. An annual subscription is cheaper than paying monthly. The current limits for every tier are on the pricing page, and the full list of 66 networks is on the supported networks page. The Viber auto-posting page has the short version of the setup.

When posts stop arriving

• The token was regenerated. Viber issues a new authentication token and the old one stops working immediately. Copy the new one into PostRSS.
• You are no longer super admin. The token comes from the channel's Developer Tools, which only a super admin can reach. Losing that role can break the connection.
• Posts arrive as text when you expected pictures. The feed item has no JPEG image. Check the raw feed rather than the integration.
• Nothing at all is posting. Confirm the feed has actually published something new since the Target was created.

Viber Channels next to Telegram, and why both can make sense

The obvious comparison is Telegram, because the two formats look alike: a broadcast channel, subscribers who opted in, no ranking algorithm in between. The differences that matter are geographic and demographic rather than technical.

Telegram skews younger, more technical and more international; its channels are a publishing medium in their own right, with audiences that follow hundreds of them. Viber skews older and far more local, and a channel there is usually one of a handful a person follows — their supermarket, their municipality, their bank. In Ukraine, Greece and much of the Balkans, Viber reaches people who have never opened Telegram; in other markets the reverse is true.

Which is why running both from one feed is often the right answer rather than a compromise. The same new article goes to both Targets, the audiences barely overlap, and the marginal cost of the second channel is a token and two minutes. Telegram sits on the Ultimate plan and Viber on Professional, so the cheaper of the two is the one most Western publishers overlook.

What to send, and what to keep out of the channel

A broadcast channel punishes volume more than a social timeline does, because every message is a notification on somebody's phone. Three habits keep a Viber channel healthy:

• Send a filtered feed, not everything. If your site publishes several categories, point the channel at the category feed that actually concerns subscribers — offers, announcements, service updates — rather than the full blog.
• Make sure the image is worth sending. Picture posts perform far better than text, and a generic stock photo attached to every item trains people to ignore them.
• Write titles that stand alone. The title is most of the message. A headline that only makes sense next to the article it sits above on your site will not carry.

None of that is automation advice, strictly speaking. But a channel that people mute is worth nothing however reliably it is fed, and the editorial decisions are made once, at the point where you choose which feed to connect.

Frequently Asked Questions

Do I need a Viber developer account to auto-post to a Channel?

No. The authentication token comes from the channel's own Developer Tools screen, which a super admin can open directly. There is no developer registration, no application to submit and no review to wait for.

Can PostRSS post to a Viber group or a community rather than a Channel?

The integration is built for Viber Channels, which are the broadcast format with an authentication token of their own. Groups and communities work differently and are not the destination here.

Will the article image always be included?

When the feed item carries a JPEG image, the post goes out as a picture with the title and link. When it does not, the item is posted as text with the link. The feed decides which of the two you get.

Who can see the posts?

The people who subscribed to the channel. A Viber Channel is a broadcast space rather than a public timeline, so there is no discovery feed carrying your posts to strangers.

Can one feed go to several Viber Channels?

Yes. Each channel is a separate Target with its own token, and the same feed can be added as a source on each of them.

How soon after publishing does a post appear?

PostRSS checks each feed every 5 minutes on standard plans and every minute on Enterprise, so a new article normally reaches the channel within a few minutes of going live.

The bottom line

Viber Channels are an underrated distribution surface in exactly the markets where Western social networks are weakest, and connecting one takes a single token. Copy it from Developer Tools, paste it into PostRSS, point a Target at your feed, and every new article reaches your subscribers as a picture or a link. It is included from the Professional plan.
