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

The problems we are facing

02/

Strict and correct determination of deadlines

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".

Solution

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

Problem

Integration of the payment system

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.

Solution

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

Problem

Authorization

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.

Solution

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.

Problem

Complex verification of speech synthesis

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.

Solution

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.

Problem

How it works

03/

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
