I got it working, amazing software.

I was thinking though, assume we use a software like wordpress, or another website which needs to verify a customer paid to allow login.

api/vi/clients will return all

is there in roadmap

and what about deleting via API?

Our next release (v2.4.0) in a few weeks will add support for filtering the API by client. The code is available now on our GitHub repo: https://github.com/hillelcoren/invoice-ninja/

There are no immediate plans to support deleting through the API but we’ll look into it for a future release.
