(Unicode C) Unicode C JCC Payment Systems - Get a User's Credential IDs for CSC

See more JCC Cyprus Examples

Demonstrates how to find the credential ids for a given user to be used with remote signing via the CSC (Cloud Signature Consortium) API.

Note: This example requires Chilkat v10.0.2 or greater.

    // 4) Calls the "credentials/info" endpoint to retrieve the credential and return the main identity information 
    //    and the public key certificate or the certificate chain associated to it.
