HSBC PAS (Payer Authentication) CCPA

[nadeemshafi9]

Hello

 

We are implementing the PAS service on our intranet application. We are receiving errors, the following will explain our process:

 

1. We submit the details to the CCPA service using cURL()

    - The CCPA service returns a HTML doc with form hidden inputs ERROR CODE  of 5(the cardholder has failed auth

      ask for another card) and a form wired to go off to the relevant card verifier (verified by visa).

            --- i am concerned we might be failing right here but i doubt it.

            * We extract the action URL from the form and the hidden values of:

                MD

                PaReq

                TermUrl

 

2. We POST these to the relevant card verifier specified in the CCPA result form using cURL().

    - The card verifier returns a html doc containing a form wired to self submit

          * we extract the url it wants to submit to, which is the TermUrl and the data:

            MD

            PaRes

 

3.We submit the values of the card verifiers response form back to the TermUrl (the CCPA server port).

    - The CCPA server returns a html doc that has a form wired to submit with and ERROR CODE 9 (the CCPA was unable

      to interpret the results from the payer authentication or enrolment service) and all the other CCPA variables like card type etc etc.

 

 

 

Do you have any suggestions.

 

Thanks you for your help
