dynamic images linked to the invoices

[Carlo Alberto Degli Atti]

Hi all,

I'm evaluating the opportunity to integrate FreshBooks in a software I'm developing, but I've a question I'm not able to answer just looking at the dev site.

Is it possible to include/attach dynamic images to invoices? I mean:

1. the user creates an invoice

2. an external endpoint is called (webhook to my app)

3. my app updates the invoice with an custom image

4. the user send or print the invoice that includes my image

I hope it's clear enough :-D

Thanks in advance for any help
