QR data for the invoice

POST /Card/Handlers/{invoiceId}/sbp

Returns the QR data for the invoice. Idempotent by construction: the QR is built from the invoice’s existing checkout session, so a repeated call returns the same one — a new session would leave the payer with two QR codes, only one of which works.

The token is verified before the database is touched: until it matches, the existence of the invoice must not be revealed — otherwise identifiers can be enumerated from the responses.

⚠️ The request and response bodies are a sandbox contract (the platform documents describe only the addresses and the meaning). The envelope follows JSON v3. sandbox_confirm_url exists in the sandbox only: there is no real SBP here, and without following that URL the widget never reaches paid.
