Tokenize a payment card (Uzcard, Humo). Returns a reusable token. After creation, verify the card with SMS code using cards_verify. Example: cards_create({ cardNumber: '8600123456789012', expire: '0399' })

Verify a card using the SMS code sent to the cardholder. Must be called after cards_create. Example: cards_verify({ token: '630e5e...', code: '666666' })

Check if a card token is valid and get card details (masked number, expiry, status). Example: cards_check({ token: '630e5e...' })

Remove a saved card token. The token will no longer be usable. Example: cards_remove({ token: '630e5e...' })

Create a payment receipt (invoice). Amount is in tiyin (1 UZS = 100 tiyin). Example: 99,000 UZS = 9,900,000 tiyin. Example: receipts_create({ orderId: 'order-123', amount: 9900000 })

Pay a receipt using a verified card token. The card must be verified first. Example: receipts_pay({ receiptId: '63...', token: '630e5e...' })

Send receipt notification to customer via SMS. Example: receipts_send({ receiptId: '63...', phone: '998901234567' })

Cancel a receipt. Paid receipts may be refunded depending on merchant settings. Example: receipts_cancel({ receiptId: '63...' })

Check receipt status. States: 0=created, 4=paid, 21=held, 50=cancelled. Example: receipts_check({ receiptId: '63...' })

Generate a Payme checkout payment link. Redirects customer to Payme's hosted page. Amount is in tiyin. Example: checkout_url({ merchantId: '5e7...', orderId: 'order-123', amount: 9900000 })
