In India there are 220 million telegram downloads that accounts around 22% of telegram downloads. It is a huge market, and telegram stores are frequently in use. This inspired us to build a telegram checkout method that integrates rapyd payment api to provide best checkout experience in galaxy.
What it does
It has a store that contains some product. We like to call the store as Daily Belly, of course funny because it has burgers, fries and drinks. You can check the menu using /menu command and add products to your basket and the set shipping details and payment details using integrated telegram webapp, On doing these you can issue a /checkout command which asks for the payment method, take details from the database and gives a replymarkup button of proceed to pay. Also since some payment methods needs an external redirect telegram webapp inline buttons are used to facilitate integration, which makes checkout experience seamless, simple and elegant for best checkout experience.
How we built it
We used golang programming language, telegram bot api, rapyd checkout tool and html, css to build and integrate the application.
