Query transaction by PIX key and identifier

GET /api/pix/transactions/pix-key/{pixKey}/{identifier}

Returns a specific transaction associated with a PIX key, searched by the provided identifier.

Identifier resolution logic: The provided value is simultaneously compared against endToEndId (PIX e2eId), externalId, and numeric id. In practice there is no ambiguity: each type has a unique format (e2eId starts with E + 32 alphanumeric chars; id is purely numeric; externalId is any other string).

Authentication

Requires a Bearer token in the Authorization header.

Parameter	Type	Required	Description
`pixKey`	string	Yes	PIX key (CPF, CNPJ, phone, email, or random EVP key)
`identifier`	string	Yes	Transaction identifier: compared against endToEndId, externalId, or numeric id
