Billing for Payme payment provider

Ready to deploy project with fiscalization, handling all errors and customer notifier in Telegram.

In project we use Nest.js, TypeScript and Prisma.

How to use it?

1. Clone this repo
2. Install dependencies with package manager (my choice is pnPM)
3. Setup your Prisma environment and connect to your database. Your scheme may differ, but be careful not to delete the main properties in Transaction and Reason. Also you need to create Reasons in your database like described in docs. It won't be superfluous to check how the code works.
4. Configure env variables like in example
5. Edit your error messages and locales
6. Run script pnpm start:dev or npm run start:dev to make sure project is works and ready to deploy
7. Deploy to the server and set your test merchant keys
8. Go to the Sandbox Page and check all tests with your Test Dev environments. Then send request to Payme supports for tests.
9. When everything is done, launch the project

What included in this project?

• all required requests for launch (whithout SetFiscalData, because we are sending fiscal data in CheckPerformTransaction)
• fiscalization
• discounts
• telegram notifier
• prisma for connecting any database
• typescript for a better understanding business logic, type all data and handling errors without pain
• easy auth, guards, filters and other Nest.js nice joys

What can be improved?

You can add your custom notifier, or add no refund option, or add your own variant for fiscalization.
