Traces an incoming deposit to one of your virtual accounts by the reference on the payer's receipt and tells you what happened to it: credited, pending, rejected, expired, or settled on the rail but not credited. For BRL the reference is the Pix end-to-end ID (common O/0 typos are also tried); for ARS it is the Coelsa transfer ID. The lookup is scoped to the authenticated company and its sub-companies.
