Setting Up the Initial Call

Calling
Cardinal.init()
:
  • begins the communication process with Cardinal
  • authenticates your credentials (server JWT)
  • completes the data collection process
By the time the customer is ready to check out, all necessary preprocessing is complete.
Each time a user begins a mobile transaction, Cardinal assigns a unique identifier to the session called a
consumerSessionId
. This
consumerSessionId
 ensures that Cardinal matches the correct device data collection results to a request.
Cybersource
 calls this session identifier,
payerAuthEnrollService_referenceID
. You must assign the value of the
consumerSessionId
 field to the
payerAuthEnrollService_referenceID
 field so that
Cybersource
 can also track the calls for each user session.
Study the code example shown below for completing the
cardinal.init()
.
Cardinal.init() (Android SDK) 
cardinal = Cardinal.getInstance();
String serverJwt = "INSERT_YOUR_JWT_HERE";
cardinal.init(serverJwt ,
new CardinalInitService() {
    /**
    * You may have your Submit button disabled on page load. Once you are 
    * set up for CCA, you may then enable it. This will prevent users 
    * from submitting their order before CCA is ready.
    */
    @Override
    public void onSetupCompleted(String consumerSessionId) {
  
    }
    /**
    * If there was an error with set up, Cardinal will call this function
    * with validate response and empty serverJWT
    * @param validateResponse
    * @param serverJwt will be an empty
    */
    @Override
    public void onValidated(ValidateResponse validateResponse, String serverJwt) {
  
    }
});
