Invoice Reminders via API

Invoice Reminders via API

Hi,

I’d like to use the Zoho Books API to send emails to my customers, but not using the invoice reminder function. Instead, I want to use the “Email Invoice” function in the API.

However, the “Email Invoice” function doesn’t seem to allow multiple invoices to be sent to one contact in a single API call, though it does allow defining the subject and body of the email. On the other hand, the “Email Invoices” function permits sending multiple invoices but does not allow defining the email subject and body.

Is there a way to send multiple invoices to a contact and define the subject and body of the email at the same time?

The reason I prefer this over reminders is that it allows me to send a list of all invoices in the email and highlight which invoices are over 30 days old.

Thank you.
