Generate invoice with API

I am trying to use the API to generate an invoice on submissions of a gravity form.

I have tried using your examples found here:
https://wp-invoice.github.io/docs/api/

I have created a test.php file and put it in my wordpress root and cut and past your create_invoice example. I have also added the following to the top of the file:
```
define('WP_USE_THEMES', false);
define("ABSPATH", dirname(__FILE__) . '/');
define("WPINC", "/wp-includes");
require('wp-blog-header.php');
require( "wp-load.php" );
```
When I run the file from a url (www.mysite.com/test.php), I do not get errors but I also do not create an invoice. What am I missing?

Or perhaps there is a better way to generate an invoice on submit of my gravity form. Perhaps the API is not needed if I am within the same site. Are there already functions, hooks, filters, that I can use within the plug in to submit an invoice?

My solution given that I am trying to integrate with Gravity Forms and I am already within the server is to do this:


<?php
include ( "wp-load.php" );
  $args = array(
      'subject'     => 'Test API Invoice',
      'description' => 'Invoice descriptive information.',
      'type'        => 'invoice',
      'user_data'   => array(
          'user_email' => '[email protected]',
          'first_name' => 'Lary',
          'last_name'  => 'Test'
      ),
      'deposit'     => 15.99,
      'due_date'    => array(
          'month' => '09',
          'day'   => '10',
          'year'  => '2013'
      ),
      'currency'    => 'USD',
      'tax'         => 10.5,
      'tax_method'  => 'after_discount',
      'status'      => 'active',
      'discount'  => array(
          'name'   => 'Your Discount',
          'type'   => 'amount',
          'amount' => 1.20
      ),
      'items' => array(
          array(
              'name' => 'Test item 1',
              'description' => 'Item 1 description',
              'quantity' => 2,
              'price' => 2.65,
              'tax_rate' => 1 //global 'tax' will be used in order to priority
          ),
          array(
              'name' => 'Test item 2',
              'description' => 'Item 2 description',
              'quantity' => 4,
              'price' => 3.85
          )
      ),
      'charges' => array(
          array(
              'name' => 'Fee 1',
              'amount' => 0.56
          ),
          array(
              'name' => 'Fee 2',
              'amount' => 0.99,
              'tax' => 15 //global 'tax' will be used in order to priority
          )
      )
  );
  
$WPI_XMLRPC_API = new WPI_XMLRPC_API(); 
$new_invoice = $WPI_XMLRPC_API->create_invoice($args);

It does the job and I can build a function to gather the form field data from my gravity form and replace the values with variables from the form and have an invoice created. Perfect.
