Os provedores Antifraude síncronos na Malga podem ser configurados para serem executados antes ou depois das transações através da opção runBeforeCharge.

Para runBeforeCharge=false, o ciclo de vida de uma transação com avaliação antifraude percorre três etapas:

  1. Pré Autorização
  2. Análise Antifraude
  3. Captura

Para garantir que a venda não será perdida e que está apta a ser processada pelo antifraude, o pagamento é pré-autorizado e, em seguida, é feita uma verificação no provedor de risco. Por padrão, caso a análise seja aprovada, o pagamento é capturado. Caso contrário, ela é estornada automaticamente.

O comportamento automatizado do ciclo de vida da transação pode ser escolhido utilizando as configurações de captureOnApprove e refundOnReprove feitas diretamente no setup de provedor de antifraude para uso na Malga.

Para runBeforeCharge=true, o ciclo de vida de uma transação com avaliação antifraude percorre duas etapas:

  1. Análise Antifraude
  2. Captura

Com esta configuração, todas as transações serão avaliadas pelo antifraude antes de serem processadas nos provedores de cobrança.

​
Exemplos de uso do antifraude

Para utilizar análises antifraude em suas transações basta estar credenciado em um provedor antifraude e configurá-lo em seu fluxo de pagamentos. Assim, será possível processar uma transação enviando as informações adicionais de antifraude.

Exemplo de cobrança com Antifraude aprovado

Após a pré autorização, se a cobrança passar pela avaliação de risco, é aprovada e capturada na sequência.

Sempre que a transação for reprovada no antifraude, por padrão faremos o cancelamento da pré autorização automaticamente. Caso a tentativa de cancelamento falhe, a transação manterá o status pre_authorized e poderá ser cancelada ou capturada manualmente, de acordo com a sua preferência.

Exemplo de cobrança com erro a acessar Antifraude

Caso um erro ocorra no provedor antifraude, o comportamento padrão do fluxo de pagamentos é retornar a transação ainda pré-autorizada.

Caso ocorra alguma instabilidade com o provedor antifraude, existem duas opções para lidar com este cenário que devem ser configuradas em seu fluxo de pagamentos: - captureOnError: Faz a captura mesmo que ocorra instabilidade no provedor de antifraude. - refundOnError: Faz o estorno da transação em caso de instabilidade no provedor de antifraude. Não pode ser ligada ao mesmo tempo que captureOnError. Nos casos onde captureOnError e refundOnError estão desligadas, a transação é retornada como pre_authorized.
