How do I get a Daftra API Key?

Log in to your Daftra account, navigate to **Settings > API**, and you will find your API Key there. You will also need your account subdomain.

What is the subdomain?

It is the first part of your Daftra URL. For example, if you access Daftra at 'mycompany.daftra.com', your subdomain is 'mycompany'.

Can the agent create new invoices?

Currently, this integration focuses on creating client profiles and listing existing invoices, estimates, and expenses. Full invoice creation is currently managed via the Daftra dashboard.
