ruby - Braintree - Transaction is successful even though fraud returns "Decline" -

i submit transaction valid card make trigger "decline" riskdata making lot of transactions card quickly. problem still makes transaction successful , submits settlement when riskdata returns "decline".

here braintree has regarding "decline" riskdata:

'decline' - transaction declined due fraud risk.

is how it's supposed function? should change configuration make reject transaction "decline"?

here reference:

#<braintree::successfulresult transaction:#<braintree::transaction id: "xxxxx"...> #<riskdata id: "xxxxxxxxx", decision: "decline"> 

_{i work @ braintree. if have more questions, please reach out our support team.}

in sandbox, braintree doesn't act on risk decision, expected behavior if aren't using fraud rejection card number.

in production, "decline" riskdata cause transactions rejected; "review" riskdata not. it's unlikely you'll ever see status of "review" in production unless obtain own merchant id kount directly , set own rules trigger response.
