«Stoloto» – is a dialog app for buying and checking the lottery ticket through SberSalute

Customer

Stoloto is the only distributor of state lotteries in Russia.

Task

Create the app that will allow users to buy tickets through the SberSalute.

SberSalute has several types of apps with which the user can interact with the assistant — these are called smartapps.

Chat App is the simplest of them. This is the dialog app that can be controlled by voice, touch, remote control or text messages.

What is the Chat App

Interesting fact

This was our first Chat App, moreover, also with payment integration — via Stoloto.

Problem

The application had to be presented at the Digital Brand Day conference. We had only 11 days to work.

Solution

To complete the task quickly, we had to limit the functionality. Using the app, you can only buy the ticket and check if it is the winning one. And only one type of lottery — "Rapido".

Strict and correct determination of deadlines

Problem

The client wanted the payment to be made through Sberbank's tools. Although they could not be integrated quickly.

Solution

We offered to make the payment using the user's phone number. The number was transferred to the Stoloto payment system, and we received a ready-made status and associated it with the client's id.

Integration of the payment system

Problem

A token valid for a very short time, is issued to the phone number in the Stoloto system. The user cannot be kept authorized in the system.

Solution

We had to check the user's phone number with each purchase. We took it out of the cache and asked again if the number was correct.

Authorization

Problem

During testing, we always check whether the assistant speaks correctly: does not confuse the accents, is it right to put pauses. But there is no such possibility in the SberSalyut yet.

Solution

We have written a separate skill for speech verification. We sent the text to the bot — and it returned the voiced version of the text.

How it works

The user calls the skill and says how many tickets he wants to buy

The assistant asks for the user's phone number

The SMS with a payment code is sent to the user's number. Then, the user sends a code — and the amount is debited from the mobile account.

We contact the Stoloto payment system. It generates a code for payment

The user confirms the fact of payment in the assistant

We are checking the payment status. If the status has arrived, the ticket goes to the "My tickets" section

The user can check the tickets. We are contacting Stoloto base. If the ticket is won, we tell you where and how to get the prize. If you haven't won, we suggest you try again
