Unfortunately, we can not send you an invoice before the payment.
When the website displays the purchase confirmation, we send you an email “CC-API: Thank you for your Purchase” with the payment details. Have a look into your spam/ junk folder, if you have not seen it!
If you opted for Check payment, the email contains all the details for your bank transfer.
If you paid by PayPal or Stripe, the payment is instant and the invoice is sent instantly.
