Hi @mavuma_dv,

If you are able to test successfully in Postman, that means your project credentials and certs are all good and the connection to Visa Network is working properly. I can't tell what is causing the error from your code, but our logs indicate that there are some type of illegal characters in the HTTP headers. Please check the headers Accept, Content-Type, Authorization are set as per the API ref docs and the base64 encoded form of username:password is identical to that generated by Postman.

Please also check out our Hello World Sample Code, it has coding samples in various languages. To download the sample code, please log in to your account and go to the General Assets section on the Dashboard page.

The problem was in the payload i had to explicitly make an array and encode before posting it. Also the userid & password i had to assign them to a variable instead of passing them directly to the header.

Thank you for the support i hope this could be useful to other's struggling with the same issue.
