Reference: InvoiceStatus

The single dictionary of invoice statuses: the same value arrives both in GET /invoices/{invoice_id} and in the callback field data.status. “Paid” is carried by the separate payment_status field, not by this status.

Value	Meaning	What to do next
`Created`	Created, awaiting further processing	For mobile billing confirm the PIN, otherwise wait for the billing outcome and re-read the invoice
`Authorize`	Awaiting subscriber authorization (PIN entry)	Call `POST /invoices/{invoice_id}/authorize`
`Active`	Authorized and ready for billing	Wait for the outcome and re-read the invoice; a callback will report it
`Billing`	Billing in progress	Re-read the invoice in a few seconds
`Processed`	Fully processed	Check `payment_status`: with `PAID` a refund is possible
`Cancelled`	Cancelled	The payment will not happen; create a new invoice to retry
`WaitContent`	Awaiting content SMS delivery	No action needed, wait for the outcome
`Blocked`	Blocked	The invoice will not progress: investigate `result_code` or create a new one
`WaitPaymentConfirmation`	Awaiting payment confirmation by the customer	The customer must open `authorization.url` — the card page or the SBP QR
`BillingAfterConfirmation`	Billing after payment confirmation	Re-read the invoice in a few seconds
`Refund`	Refund initiated	The result arrives in the `refund.updated` callback (`refund.completed` in the legacy envelope)
`Refunding`	Refund in progress	The result arrives in the `refund.updated` callback (`refund.completed` in the legacy envelope)
`Failed`	Processing failed	Check `result_code` and `billing_result`; create a new invoice
