What is needed in order to conduct test transactions with the new MPI version?

You need to issue a self-signed certificate (RSA Keypair SHA2-256) that will include private and public certificates. You can create a self-signed certificate using a Java key tool or open ssl.

You must then share via email the public certificate to Cardlink (ecommerce_support@cardlink.gr) in order to validate the messages.

To learn more, please refer to the technical manual.
