Update
Discover Authorizations for Credit/Returns
Card-Not-Present / Card Present
The Change: Effective with Fall 2018 release, Discover added new rules to allow merchants to submit authorization requests for credits related to returns or canceled services. With the Spring 2019 release, Discover will require that acquirers and processors support authorization requests for credits/refunds. Authorization specifications and systems will be updated to meet the Spring 2019 acquirers and processors mandate.
The Impact: Discover does not have a defined date for merchant support.
The Timing: TBD
