I am implementing 3DS on REST API, I have been doing some tests and I was able to get the authentication window for 3DS just fine, a few days ago, I started getting error: A message element required as defined in Table A.1 is missing from the message. deviceChannel.
I don't find any instructions on adding this to the REST API code. I have also tried the live test platform on Cybersource that is found here but still getting the same error.
Has anyone faced this and how can I resolve it? Thank you
I also faced a similar issue, but I was able to resolve it by passing the reference id gotten from :
