VTC Global vs Transaction: order of precedence

[bpsymano]

Is there an order of precedence when creating customer rules?

Specifically, will the following  global (decline all) transaction of:

{
   "globalControls":[
      {
         "shouldDeclineAll": true,
         "isControlEnabled": true,
         "userIdentifier": "abhi-539d-4f93-ba00-77ef9ff873a2",
         "shouldAlertOnDecline": true,
         "declineAllNonTokenizeTransactions": true
      }
   ]
}

Override an individual transaction control of:

{
   "transactionControls":[
      {
         "shouldDeclineAll": false,
         "isControlEnabled": true,
         "controlType": "TCT_E_COMMERCE",
         "userIdentifier": "abhi-539d-4f93-ba00-77ef9ff873a2",
         "alertThreshold": 50,
         "shouldAlertOnDecline": true
      }
   ]
}

 I am trying to determine the best way to implement a logical DECLINE_ALL without introducing unintended consequences of previously configured TransactionControls.

Thank you,

Bruce

Hi @bpsymano,

I have reached out internally to get information for the order of precedence when creating Customer Rules. I will post the answers here once I hear back from our product team. Thank you for your patience.

Hi @bpsymano,

My apologies but I have been unsuccessful at getting the information you requested. If you have an active project implementing VTC, please email your project name to developer@visa.com. I will continue to follow this. Thank you.

Hi @bpsymano,

Thank you for your patience. There is a VTC Hierarchy in the way that the Control rules are applied: GLOBAL is always first, then other controls such as ecommerce will apply. Hope this helps, please reach out with further questions.

Thank you for the reply Stacey.

One last clarification...

I assume that if I lock a card with a global control (globalControls : [{shouldDeclineAll : true, ...}]), that this trumps any transactionsControls set for specific transaction types (controlType).

i.e. A transactionControls:[{shouldDeclineAll : false, controlType: TCT_ATM_WITHDRAW, ...}] will get ignored.

Is my understanding correct?

Thank you,

Bruce

Hi @bpsymano,

Yes you are correct. GLOBAL will overwrite the other controls.

Many controls can be present on a document, at a given time.  When a transaction occurs, all transactions are blocked/declined based on the VTC controls-hierarchy. In that controls-hierarchy, the GLOBAL is the first control to be checked.
