# fin_deletar_transacao

Deleta apenas a transação especificada pelo ID. QUANDO USAR: remover uma transação lançada por engano ou duplicada, ou remover uma parcela específica de um parcelamento sem afetar as outras. CAMPOS: - transaction_id: string UUID — ID da transação (obrigatório). REGRAS DE NEGÓCIO: - Deleta APENAS a transação especificada. Se a transação faz parte de um parcelamento, as outras parcelas do mesmo installment_group_id permanecem intactas. - Exceção: perna de câmbio (as duas linhas de fin_cambio). Apagar uma perna apaga as duas, porque câmbio pela metade deixaria um saldo andando sem o outro; a resposta traz removed_count: 2 e removed_exchange_pair (exchange_pair_id e os transaction_ids das duas). Fora do câmbio, removed_count é 1 e removed_exchange_pair não vem. A perna órfã (câmbio que ficou com uma perna só, sobra de antes) apaga só a si mesma, com removed_count: 1 e removed_exchange_pair de um id. - Para apagar um grupo inteiro de parcelamento, delete cada parcela individualmente usando os IDs retornados por fin_buscar_transacoes ou fin_todas_transacoes. - A operação é irreversível.
