Usage

API

First, you need to create your application and get an API token. Open @CryptoBot or @CryptoTestnetBot (for testnet), send a command /pay to create a new app and get API Token.
Next step: try to call a simple get_me() method to check that everything is working well:

fromasyncioimportrunfromCryptoPayAPIimportCryptoPaycp=CryptoPay('YOUR_API_TOKEN')
print(run(cp.get_me())) # Returns Application object.

You can use testnet for testing your applications. Defaults is mainnet.

fromCryptoPayAPIimportCryptoPaycp=CryptoPay('YOUR_API_TOKEN', testnet=True)

You can find all available methods in Methods chapter.
Also, you can get supported assets, paid button names and invoice status:

fromasyncioimportget_event_loopfromCryptoPayAPIimportCryptoPayfromCryptoPayAPI.schemasimportAssets, PaidButtonNames, InvoiceStatuslp=get_event_loop()
cp=CryptoPay('YOUR_API_TOKEN')
print(lp.run_until_complete(cp.create_invoice(
Assets.USDT, 5.25,
description='Example page for $5.25!',
paid_btn_name=PaidButtonNames.VIEW_ITEM,
paid_btn_url='https://example.com'
))) # Prints information about created invoice.print(lp.run_until_complete(cp.get_invoices(
Assets.USDT, status=InvoiceStatus.PAID
))) # Prints all paid invoices.

Webhooks
