I interact with the
zoho invoice API quite a bit and it seems that you guys have quite a bit of validation on the data that gets created in zoho.
For example contact and invoices fields prevent some special characters from being used when creating entries in zoho.
This is great, but it doesn't seem to be documented anywhere.
Where can I find our more information about what you guys actually validate so we can make sure we have similar validation or at least sanitise the data before passing it to zoho.
