When using the API it would be impractical to issue an invoice for every single domain registration, renewal and transfer. Instead we allow our resellers to define the invoicing period themselves in the reseller settings.
If you did not change the default values, you will receive one invoice per day with all billable operations done using the API from the last invoice till the current one. If there are no billable operations then you don't get any invoice.
To set a invoice period, please login to your account,
- Click on the button 'My Account' and from the drop down click on 'My Profile'
- Click on 'Reseller Settings'
- You can then set the invoice period here at "Send invoice for products provided with API:"
