Retainer invoices API is missing

[jvandervalk]

Hello,

if I'm correct I don't see an option to see my retainer invoices. Is it possible to make this?

Hi, yes that was an addition to the zoho books apis that isn't yet available here.
If you feel like it, send in a PR, it's should be pretty straightforward. You just need to create a Module and a Model class for it

Thanks!
