Q: Is invoice_amount mandatory when creating an invoice?
A: Short answer - YES, invoice_amount is mandatory.
- You can create the invoice without an amount but you can not send it. e.g. try sending in a new API call with the send after = 1 and you should get an error message.
- You can create and NOT send, then log in and edit and send and you should see the total be auto calculated.
- One nuance is that if you use a pre-existing invoice num or ID, you will get back invoice_amount since it is editing an existing invoice versus creating a new one.
