Conditions for offering step-down flow

Original transaction submitted to Payment App must fail in certain way and there must be appropriate config (1)

• Payment Processor must support step-down flow. At the moment only Credit Card processors support this.
• Transaction amount must be greater or equal to USD 2.5. Non-USD currencies are converted to USD using Currency_Rates_Model before this check.
• Original transaction must fail with either
  • NSF error - code 608, or
  • Declined General - code 610 and submitted Credit Card is either prepaid or gift card (2)

Offering the step-down flow to partner

If above conditions are met, and there is a configuration match (3) then Payment App will offer step-down flow to Partner.
Step-down flow is offered by setting following additional parameters in transaction.finish response (all other parameters in response will be set to those of original transaction) :

• step_down_condition = true
• step_down_percent
• step_down_retry = 1
• step_down_amount

Partner follows step-down flow

When Partner detects that the step-down flow is offered by transaction.finish response (by checking step_down_condition parameter), he can opt to follow step-down flow.
