Create an invoice

Creating an invoice

Now that an access token has been provided, we are now able to create invoices in the N-Genius Online gateway. To accept a payment from a customer, an order is always required so that we have something to interact with in all our API interactions with the gateway, and on the Portal user interface.

HTTP Request Method: POST
