    Business Rules

    Validations:

    • The e2e path parameter is required and must be the EndToEndId of a received PIX cash in
    • Only PIX cash in transactions are returned. EndToEndIds of transfers you sent will not be found by this endpoint

    Important Notes:

    • The id returned here is the value expected by the chargeback endpoint in the transaction_id field
    • Use transaction_chargeback_value to know how much of the cash in has already been refunded before requesting a new chargeback
    • Payer fields depend on the information supplied by the payer's institution and may be returned as null
