CyberSource::PayerAuthSetupRequest is not working, returns 400 constantly

[alexmikulaninec]

Hi, I'm integrating Cybersource payments into our systems and am using this gem to call the api. In the front end I have flex microform that gives me a token and I don’t have control over card details.

When I try to setup payer authentication for 3DS payments I send MerchantID, key and secret alongside with client reference code and decoded jti token from flex token and always receive 400 with "reason\":\"INVALID_DATA\",\"message\":\"Declined - One or more fields in the request contains invalid data\".

I'm following this example https://github.com/CyberSource/cybersource-rest-samples-ruby/blob/master/Samples/PayerAuthentication/setup-completion-with-flex-transient-token.rb

It also happens on your live console https://developer.cybersource.com/api-reference-assets/index.html#payer-authentication_payer-authentication_setup-payer-auth_samplerequests-dropdown_setup-completion-with-flex-transient-token_liveconsole-tab-request-body so I wonder if there's a bug?

Thank you.

Some backend config changes were needed on Cybersource side to make this work. However there's no clear docs stating this.

@alexmikulaninec Could you tell me exactly what is the issue and how to resolve it?

@ahmedalashii I contacted CyberSource support team and they made changes in the config for the account that was being used so that did the trick. It's not documented so it was a pain to figure out. Hope it helps.
