Issues with Cybersource Secure Acceptance Payment Integration

[piyushbeli]

Description:

I am experiencing issues with the Cybersource Secure Acceptance payment integration. Despite following the documentation and generating the required parameters and signature, I consistently encounter session timeouts and timestamp mismatches.

Steps Taken:

1. Setup and Configuration:

   • Implemented the integration using Node.js with the provided access key, profile ID, and secret key.
   • Ensured the server's clock is synchronized using NTP.

2. Code Implementation:

   • Generated the signed_date_time and other required parameters.
   • Created a signature using HMAC-SHA256 as specified in the documentation.
   • Posted the data to https://testsecureacceptance.cybersource.com/pay using an HTML form.

Every time I get this response 

"You are not authorized to view this page. The transaction has not been processed."

I have already checked this link https://support.cybersource.com/knowledgebase/Knowledgearticle/?code=000002283 and according to me every data is passed correctly.

It would be a great help if you could let me know what I am missing or doing wrong. Here is one of the reference error no:  E-5B845C30432C4ACE935F7440515032E8
