On Invoice Ninja website, it seems that the API access is only available to the paid versions. What about in the self-hosted version (on cloudron), is it free to use the APIs to create invoices and download them as PDFs?
All I need is a way to create invoices programmatically and print them out. No need to accept payments.
Seems to be no problem. API documentation --> https://invoice-ninja.readthedocs.io/en/latest/api.html
