Get a checkout

Full checkout detail (owner view). pix_payload is present only while pending. Poll until a terminal status (see the status enum) or subscribe to checkout.* webhooks. Requires scope merchant_read on the API-key path.

processing means the payer's money reached us — it does NOT mean the money has landed in the merchant's wallet, and a checkout can sit there for days while a hold runs. It is also not a settled outcome: a sale in processing can still resolve to cancelled (a refunded or reversed payment — see rejection_reasons). delay_until says when the money lands (null until the provider answers with a date) and vault_hours says whether it was held at all. Releasing the order at processing or waiting for completed is the merchant's own policy; this endpoint publishes the facts either choice needs.
