DEVNU / SOLUTION

Telegram bots and Mini Apps

For ordering, services, notifications or reseller operations—connected to an API and database rather than a set of isolated commands.

01 / Who it is for

Businesses whose audience or operations live in Telegram and need a traceable, manageable workflow.

02 / Problem signals

If these states look familiar, the problem is larger than interface polish or tooling.

01

Bots with no admin or history

02

Lost payments or orders

03

Complete reliance on manual messaging

04

Weak webhook and access security

03 / Approach

Bot, Mini App, API and administration are designed as one product. Order, payment and external actions remain idempotent and reviewable.

04 / Delivery process

Six stages, each ending with a clear deliverable.

  1. 01

    Understand the problem

    Review the current system, users, operating flow and real constraints.

  2. 02

    Define the scope

    Write down deliverables, exclusions, priorities and acceptance criteria.

  3. 03

    Architecture and design

    Align content, workflows, data and interface before implementation.

  4. 04

    Incremental development

    Make core paths visible early and keep every release reviewable.

  5. 05

    Test and release

    Check failures, mobile, accessibility, data and deployment before launch.

  6. 06

    Maintain and improve

    Continue with explicit ownership for logs, health, backups and future changes.

06 / FAQ

Questions for a sound decision

Is a bot enough, or is a Mini App needed?

A bot is enough for short flows; a Mini App makes sense when display, selection or data entry becomes more complex.

How are payments tracked?

Each transaction has an identity, state and reconciliation path, and repeated callbacks must not duplicate an order.

Can it run on our server?

Yes. Resource needs, secrets, webhooks, TLS, backups and monitoring are defined in deployment.
