Question

What s the different between the various account numbers I see the following attributes on the account acct number internal acct number external HADE AccountNumber My goal is to display the last four characters of the account number to the user on a form where they are selecting an account to make a payment It seems like the HADE AccountNumber is what we need but I wanted to double check

The account number setup varies depending on the customer.

Generally the acct_number_internal sent by HQ with the request will have the account in a format the FI is comfortable with displaying to the end user. It could be either masked or unmasked.

If you need the full account number there are acct_number_internal_unmasked and acct_number_external_unmasked.

A HADE with the name "AccountNumber" is rare.
