_LANGUAGE_ 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.

// 2) Calls the "oauth2/token" endpoint to get the OAuth2 authorization token via client credentials (using the clientId and clientSecret).
// 3) Calls the "credentials/list" endpoint to get the list of credentials associated with the userId.
// 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.
//    The Chilkat certificate object is loaded with the retrieved certificate.
