How to email a credit note via API with default email template?

Hello,

I send credit notes via API using

https://www.zoho.eu/invoice/api/v3/#Credit_Notes_Email_a_credit_note but without

JSONString. It sends a credit note to default contact email and uses a default email template.

Now I have to use JSONString because of the need to email credit notes to specific email addresses. It requires to set subject and body. But that body replaces the default email template.

Is it possible to send a credit note to specific email address using the default email template?
