Java SDK, form.jsp file -- Any restrictions on the random sequence used for fingerprint creation?

timc — Thu, 05 Mar 2015 15:54:17 GMT

The java SDK file form.jsp shown here:

https://github.com/AuthorizeNet/sdk-java

includes the following line of code...

Fingerprint fingerprint = Fingerprint.createFingerprint(
apiLoginId,
transactionKey,
1234567890, // random sequence used for the finger print creation

amount);

Can anyonne tell me the significance of that number, 1234567890? Is this number fine to leave as it is, forever? Or, should I replace it with a 10-digit number that is randomly generated each time? Or, something else?

Based on trail and error, it appears this must be a different number each time. In java, you can use the following to generate a random 10 digit number:

long random10DigitNumber = (long) Math.floor(Math.random() * 9000000000L) + 1000000000L;
