Creation of a multichannel chatbot (TG/VB/IG) with LiqPay and architecture for localization (UA/PL/EN)

Budget: 18000 UAH Deadline: 18 days

Ihor, for this project, I recommend SendPulse. It supports Telegram, Viber, and Instagram in one panel, allows transferring scenarios between channels, working with tags, variables, API requests, and webhooks. This will enable building a single basic funnel logic and then adapting it to the technical limitations of each messenger without creating three independent systems.

I will immediately design the main Ukrainian funnel modularly: texts, videos, tariffs, and service variables will not be rigidly tied to the scenario. This way, the UA/PL/EN versions can be added by copying the structure and replacing the content while maintaining the same analytics and tagging system.

I will connect LiqPay via API and webhook. After confirmed payment, the system will determine the tariff and discount, record the share in favor of the Armed Forces of Ukraine, assign the appropriate tags to the user, and create a time-limited personal link to the video. A simply hidden page does not provide protection, so access must be verified by the website server using a signed token.

Applications for online or offline coding with contacts and selected services will immediately go to the administrator's working Telegram chat. Before launch, I will test all tariffs, discounts, repeated webhooks, invalid links, tagging, and funnel progression in each channel.

Full implementation will take 14–18 calendar days. The cost is 18,000 UAH. The price includes three channels, LiqPay, access system, applications to the administrator, tagging, preparation for UA/PL/EN, deployment, and testing. The tariffs for SendPulse, Viber, hosting, and LiqPay commissions are paid separately.

Good day!

For this task, we recommend SendPulse as the base: one panel for Telegram, Viber, and Instagram Direct, normal operation with tags and segmentation, as well as a more convenient start for a multichannel funnel. Smart Sender makes sense if the priority is a Telegram-first scenario, but for your set of channels and further scaling, SendPulse looks more practical.

Architecturally, it is better to separate the scenario part and critical business logic: the builder handles dialogues, branching, and tagging, while the own backend processes LiqPay webhooks, payment statuses, generates one-time links to a hidden page, logs events, and transmits applications to the Telegram chat of the administrator. This separation reduces dependence on platform limitations and simplifies maintenance.

From a technical point of view, there are several important risks here. First, payments through LiqPay need to be processed idempotently to avoid duplicates with repeated webhook messages. Second, Instagram Direct and Viber have their limitations on scenarios, so it is better to design the logic not "tightly" to one channel, but through a common core. Third, access to videos should be better protected not just by a hidden page, but by a signed one-time URL with an expiration date and user/order binding.

Multilingualism should be laid out immediately as a separate layer of content UA/PL/EN, so that switching languages is a starting parameter, not a rewriting of the entire funnel. Deductions of part of the payments to the Armed Forces of Ukraine should also be formalized as a separate distribution and reporting rule, so as not to mix this with the basic acquiring logic.

For an accurate assessment, we only need to clarify whether we are launching the MVP immediately in three channels or first making Telegram the main channel; whether all scenarios by tariffs are already fixed; and what specific mechanism for deductions to the Armed Forces of Ukraine is needed — a fixed percentage or separate categories of users.

Hello! I recommend implementing on SendPulse: Telegram, Viber, and Instagram can be managed from one cabinet, and the scenarios can be easily scaled for UA/PL/EN.

I will implement:

the logic of the sales funnel for three messengers;
integration of LiqPay with tariffs, discounts, and payment verification;
secure video delivery through personal links;
submission of applications to the Telegram chat of the administrator;
tagging users and analytics of stages;
architecture for the quick launch of Polish and English versions.

Payment and access to content should be checked through a separate server module to avoid payment substitution and the transfer of permanent links.

Estimated time: 15–25 working days. Expand

Good day!

I can fully implement this sales funnel "turnkey" — from designing the logic to launching, integrations, and testing.

For this project, I would recommend Smart Sender.
Main reasons:
• one control panel for Telegram, Viber, and Instagram Direct;
• flexible scenario builder with scalability options without restructuring the entire logic;
• convenient tagging, segmentation, and automation system;
• simple integrations via API and webhooks;
• architecture that is easy to scale to UA/PL/EN without duplicating the entire funnel.

I would suggest building the system modularly from the start:
• unified logic for all messengers;
• separate language blocks that can be quickly connected after translating the content via HeyGen or Rask;
• LiqPay integration with automatic access issuance after successful payment;
• secure video distribution through unique links;
• transfer of consultation or coding requests to the Telegram administrator;
• complete user tagging by source, funnel stage, purchases, and behavior for further mailings and analytics.

Before launching, I also recommend thinking through the analytics of the entire funnel right away: from the first contact to purchase, to see the conversion of each stage and quickly identify bottlenecks.

If needed, I can also help optimize the sales funnel itself to increase conversion, not just implement it technically.

I would be happy to discuss the project details. Expand

Good day!

The project is clear. Similar sales funnels with chatbots, payment integration, digital product delivery, and application automation are exactly the direction I work in.

For this project, I recommend SendPulse. It allows managing Telegram, Viber, and Instagram Direct from a single platform, supports CRM, segmentation, tags, mailings, and API integrations, which will simplify the further development of the system.

Preliminarily, I see the architecture as follows:

1. a unified logic for three messengers;
2. integration with LiqPay;
3. automatic access issuance after payment;
4. transferring applications to administrators in Telegram;
5. tagging users for analytics and repeat sales;
6. preparing the structure for quick scaling to other languages without restructuring the entire funnel.

Before the final assessment, I would like to clarify a few points:

1. how is secure access to the videos on the site planned to be implemented;
2. how exactly should the discount system and deductions for the Armed Forces of Ukraine work;
3. are recurring payments needed or just one-time purchases.

I would be happy to discuss the architecture and propose an optimal solution. Expand

Good day!

Regarding the recommended platform-builder — I suggest SendPulse: it is one of the two that natively manages all three required channels (Telegram, Viber, Instagram) from one panel, and has built-in integration with LiqPay — payment buttons can be placed directly in the branches of the scenario, without a third-party connector. This is important for your case with multiple tariffs (200/390/800/1500/3000 UAH) and discounts for specific categories — it is more convenient to keep the logic of payment branching in one place.

An alternative is Smart Sender, the official partner of Viber for Business. If there are difficulties with verification or provider tariffs during the connection of Viber Business Messages, this is a worthy option to consider, but LiqPay connects there through a third-party service (Onlizer), not directly, and there is less data on the Instagram side — therefore, as a start for a multichannel funnel, SendPulse looks more reliable.

Regarding the tasks from the description:

A scenario with branching into three channels + LiqPay payment for tariffs (with a deduction % for the Armed Forces of Ukraine) — standard configuration of SendPulse flow, a separate branch for each tariff.
Secure content delivery — after payment, the bot generates a unique link to a hidden page on the site; it is advisable to immediately set time limits for the link's lifespan/one-time use to avoid sharing among users.
Collection of coding requests with instant forwarding of contacts to the admin Telegram chat — implemented via a webhook from the flow directly to the chat.
Tagging users at each stage of the funnel — standard SendPulse function for further analytics and mailings.
Architecture for UA/PL/EN — I will implement a language switch at the start of the bot as a separate branching point, so that duplication for PL/EN (for translation via HeyGen/Rask) is reduced to copying the branch with text block replacements, without reworking the logic.

I am ready to discuss the details and the estimated budget/timeline. Expand

Igor, I see the need to build a flexible architecture where each language version will be a separate module, and the logic for content delivery is tied to the user's payment status. For Smart Sender or SendPulse, it is important to correctly configure the transfer of user parameters when transitioning from the site, so that the bot understands which specific info product to provide after the transaction.

I will propose a structure with global variables for languages, which will allow for easy duplication of funnel branches without reworking scenarios for Polish or English. We will also set up webhooks for automatic payment confirmations and the division of donations within the payment system.

Do you plan to use the API to generate personalized links to video content, or will the delivery occur through static closed pages on the site?

Hello.
The development of a scalable sales funnel will be carried out with a focus on architectural flexibility, allowing for easy scaling to new languages and products. For functionality implementation, I recommend Smart Sender, as this platform provides high integration capabilities for LiqPay with dynamic rates and reliable content delivery through unique links to secure pages of the site. My experience in deploying similar multilingual systems with complex payment integrations and tagging systems allows for the prompt configuration of bot logic and instant submission of requests to the administrator. I suggest discussing all implementation details, final budget, and timelines in private messages.
