Simple Invoices - Forum

Hi,
We have a php time sheet application on the same server as SimpleInvoices.
We invoice customers based on project time spent.

The api call via the http post works well (see wiki) but is very manual - so......

1. Can the post also invoke an automatic SAVE of the invoice

2. If we are not logged in, can the invoice info be saved and used automatically after the login is completed.

3. Ideally we would like to add invoice information using CURL - would it be possible to do this?
The curl call would initiate a login (if not logged in already), add the invoice information, and save the invoice.
All the data validation can be done before the curl call to ensure accuracy.

Thanks
