Create a flex control on Pix transactions

Using flex controls

The only way to set up flex controls at the program level is to use Pismo Control Center. This means that a control affects only the accounts within a specific program. To create flex controls at the account or card level, use the appropriate endpoint in the Flex controls API.

To apply this flex control, follow the procedure Add a flex control but use the following information:

  • On the Select a control type screen, select Cumulative control.
  • On the Select processing codes screen, add the processing codes to be included in this flex control (any processing codes associated with Pix transactions).
  • On the Limits and time period screen, do the following:
    • Select Spending as the limit type.
    • Select Per day and specify the timezone the control must use.
    • Set the Reset period to 7:00 AM. This is the time when the limit resets and can be any hour outside of the nightly range.
    • Enter the spending limit amount 1,000. Control Center displays a message like Deny transactions for the selected processing codes after $1,000 daily, starting daily at 7:00 AM, XXX/XXXX time zone. Use this message to confirm that this is the result you want.

You don't specify the currency to use because this is determined by the programs that will use the flex control.

  • On the Conditions screen, do the following:
    • Select the box for Week, Month, Time of day.
    • Select the box for Time of Day and then select the start time 8:00 PM and end time 6:00 AM.
    • Click Add condition.
  • On the Program screen, select the programs to which you want to apply this control.
  • On the Review and apply flex control screen, do the following:
    • Review and confirm each setting by selecting its check box.
    • Enter a name for your control (such as Nightly_PIX_Limit) and the Deny code that you want to receive whenever a transaction exceeds the limit (such as PIX_nightly_limit_reached).
  • Select Create control and activate now and then click Finish.
