Development of a Viber bot

Good day! I represent the Nexus Core team. Our team acts as the technical department for arbitration teams, handling all technical aspects while you focus on traffic. We have carefully reviewed your task regarding the setup of a Viber bot for mass and selective content distribution to over 100 channels where administrator rights are provided. Since mass distribution across such a number of sources creates a serious load on the API and carries risks of blocking, we propose implementation on a professional stack: Node.js in conjunction with the Viber REST API for flexible queue management, PostgreSQL with Prisma ORM for reliable segmentation of the channel database, and Next.js for developing a user-friendly admin interface. We will integrate a rate limiting system and retry logic to ensure messages are delivered consistently without violating platform rules. To ensure 24/7 operation, we will deploy the solution on a VPS via Docker, which guarantees autonomy and eliminates dependence on third-party builders. Before we start, it is important for us to clarify a few technical points: what type of content is planned for distribution, is a scheduled delayed posting feature needed, and is there a necessity to collect detailed view statistics for each individual channel? Our cases are under NDA; however, in private messages, we are ready to provide detailed information about implemented projects of a similar class and discuss the architecture of your system. Since the final cost always depends on the technical task and volumes, we will provide an accurate calculation after a brief discussion of the details. Please write in private messages — we will clarify the details and provide a fixed cost with a breakdown by stages and agreed timelines.

Working with a large number of chats requires optimization of requests to the Viber interface to avoid penalties and delays. I will write a microservice in Go with Viber Sending API integration and Redis for the task queue, which will ensure stable content delivery.

For targeted mailings, I will create API endpoints or a simple control panel for selecting the necessary chats. The solution will be containerized in Docker for easy deployment on your server.

Development cost: 6000 UAH. Maintenance (monitoring and updates) – 500 UAH/month. You provide the platform: Viber Business API.

Additionally, instead of a basic bot, for 1500 UAH, a solution with integrated analytics and reports on message delivery for each channel can be developed. This will allow for accurate assessment of mailing effectiveness, identification of problematic channels, and optimization of communication strategy, increasing reach and audience engagement.

There are a whole bunch of questions and clarifications that need to be discussed.

I can do this in Python. I have extensive experience in bot development and can host the bot on a VPS service. I can also implement functionality so that you can easily change the messages for sending.

Contact me to discuss the details.

Good day!

I have experience in developing bots for messengers on Node.js and I am ready to implement your task. Unlike constructors, a custom solution on Node.js will allow bypassing platform limitations and ensure stable message sending to a large number of channels (100+) without delays.

Technical solution:
- Platform: Custom development on Node.js (using the official Viber REST API). This is the most reliable option that does not require a monthly subscription fee to third-party constructors.
- Database: MongoDB or PostgreSQL for storing the list of all channels and creating separate categories (groups of channels) for selective mailing.
- Control panel: A simple admin panel can be implemented (Web interface on React) or manage the mailing through special commands in the Viber bot itself.
- Message queue: I will implement a "queue" system so that messages are sent smoothly, without causing blocking from Viber due to excessive activity.
…
Sincerely, Timur

Good day 👋

I have already implemented a similar bot for mass mailing to a large number of channels, so I understand the specifics of the Viber API and the limitations of the platform well.

I can quickly set up a stable mailing system for 100+ channels with selective sending capabilities and a convenient admin panel.

I am ready to discuss the details and start in the near future.

Good day!
I can set up a Viber bot that will automatically send messages to 100+ channels where it has been granted administrator rights, as well as allow separate selection of groups of channels for targeted mailings.

Implementation: Viber Bot + Make.com (or server logic via webhook/API) — a stable solution with scalability and convenient management of mailings.

Functionality:
* mass sending of messages to all connected channels
* creation of channel lists (segments)
* targeted mailing
… * simple message management panel

I am ready to discuss the details and suggest the optimal architecture for your work scenario.

Good day!
I can set up a Viber bot that will be able to send messages immediately to all channels where it has administrator rights, as well as to a selected list of channels if needed. Implementation through the official Viber Bot API.
The bot will operate on a server/VPS, with the ability for flexible management of channel lists. I will provide brief support after delivery and explain how to use the bot.

Good evening. Can you send the technical specifications for the bot steps privately? There is a service for sending.

I can help with setting up a Viber bot.
What needs to be done:
Mass sending of identical messages to 100+ channels (where the bot is an admin)
Separate sending to a selected list of channels
Convenient management of channel lists
Experience: I have experience with Telegram bots (broadcasts, mailings, integrations). The Viber Bot API works on a similar logic — I can implement it.
Technically: Python or Node.js, Viber Bot API, storing channel lists in a database or config, possibility of an admin panel for managing mailings.
What needs to be clarified:
Are there already Viber channels and are you ready to add the bot as an admin?
… What type of messages: text, images, buttons?
Is an admin panel needed for managing mailings or is a config/script sufficient?
I am ready to discuss details and estimates.

Hello! I have experience working with the Viber API and developing mass mailing systems. I am implementing a bot in Python that will allow flexible management of segmentation: sending messages to all 100+ channels simultaneously, as well as to selected lists.

Development cost: 6000 UAH.

Maintenance: only server rental (VPS) - about $5-7/month.

Platform: cloud server (Hetzner or Railway) for stable operation 24/7.

Please let me know in what format your list of channels is currently stored (Excel or just a list)? Write to me.

Good day!
I professionally develop Viber bots in Python (Viber API). I am ready to implement mass mailing to 100+ channels and individual messages.

The bot will be deployed on a cloud platform (AWS/Heroku). We will discuss the cost of development and maintenance after clarifying the details.

Write to me in private messages.

Good day.

I have experience in developing bots and automating mass mailings through API. I have implemented solutions for managing channel lists and segmented dispatches.

I am ready to implement your project.
I suggest we move to private messages to clarify the technical specifications, agree on the cost and timelines.

Good day. What types of messages (text, images, files) will the bot be sending?

I will discuss detailed terms and budget in personal correspondence.

I will implement this project as follows:
1. I will set up the bot on a stable platform, for example, on Python using the Viber API.
2. I will integrate a system for mass distribution to 100+ channels from a centralized cabinet.
3. I will implement a separate tool for selective distribution to specific channels from the list.

… The total cost of developing such a bot is 8000 UAH. Monthly technical maintenance and support will cost 1500 UAH. Implementation platform: Python using the official Viber API and hosting for continuous operation.

Thank you for considering my proposal. I am enthusiastic about the opportunity to work with you!
