We use a platform called STANNP to send out mail currently for some of our other services. Is there a way we can get FreeAgent to do this via the API?
What would be ideal is if we could add a custom field into the invoices section that allows us to say “Send By Mail”. and get a list of invoices that are marked as unsent with this attribute that we can then trigger the STANNP API with?
I’m open to other suggestions on how we can achieve this, or if we can via the API? Obviously I don’t want to send duplicates to clients that do use emails.
