// CreateInvoice takes context, subscriptionId, body as parameters and
// returns an models.ApiResponse with models.InvoiceResponse data and
// an error if there was an issue with the request or response.
// This endpoint will allow you to create an ad hoc invoice.
// ### Basic Behavior
// You can create a basic invoice by sending an array of line items to this endpoint. Each line item, at a minimum, must include a title, a quantity and a unit price. Example:
// ```json
// {
// "invoice": {
// "line_items": [
// {
// "title": "A Product",
// "quantity": 12,
// "unit_price": "150.00"
// }
// ]
// }
// }
// ```
// ### Catalog items
// Instead of creating custom products like in above example, You can pass existing items like products, components.
// ```json
// {
// "invoice": {
// "line_items": [
// {
// "product_id": "handle:gold-product",
// "quantity": 2,
// }
// ]
// }
// }
// ```
// The price for each line item will be calculated as well as a total due amount for the invoice. Multiple line items can be sent.
// ### Line items types
// When defining line item, You can choose one of 3 types for one line item:
// #### Custom item
// Like in basic behavior example above, You can pass `title` and `unit_price` for custom item.
// #### Product id
// Product handle (with handle: prefix) or id from the scope of current subscription's site can be provided with `product_id`. By default `unit_price` is taken from product's default price point, but can be overwritten by passing `unit_price` or `product_price_point_id`. If `product_id` is used, following fields cannot be used: `title`, `component_id`.
// #### Component id
// Component handle (with handle: prefix) or id from the scope of current subscription's site can be provided with `component_id`. If `component_id` is used, following fields cannot be used: `title`, `product_id`. By default `unit_price` is taken from product's default price point, but can be overwritten by passing `unit_price` or `price_point_id`. At this moment price points are supportted only for quantity based, on/off and metered components. For prepaid and event based billing components `unit_price` is required.
// ### Coupons
// When creating ad hoc invoice, new discounts can be applied in following way:
// ```json
// {
// "invoice": {
// "line_items": [
// {
// "product_id": "handle:gold-product",
// "quantity": 1
// }
// ],
// "coupons": [
// {
// "code": "COUPONCODE",
// "percentage": 50.0
// }
// ]
// }
// }
// ```
// If You want to use existing coupon for discount creation, only `code` and optional `product_family_id` is needed
// ```json
// ...
// "coupons": [
// {
// "code": "FREESETUP",
// "product_family_id": 1
// }
// ]
// ...
// ```
// ### Coupon options
// #### Code
// Coupon `code` will be displayed on invoice discount section.
// Coupon code can only contain uppercase letters, numbers, and allowed special characters.
// Lowercase letters will be converted to uppercase. It can be used to select an existing coupon from the catalog, or as an ad hoc coupon when passed with `percentage` or `amount`.
// #### Percentage
// Coupon `percentage` can take values from 0 to 100 and up to 4 decimal places. It cannot be used with `amount`. Only for ad hoc coupons, will be ignored if `code` is used to select an existing coupon from the catalog.
// #### Amount
// Coupon `amount` takes number value. It cannot be used with `percentage`. Used only when not matching existing coupon by `code`.
// #### Description
// Optional `description` will be displayed with coupon `code`. Used only when not matching existing coupon by `code`.
// #### Product Family id
// Optional `product_family_id` handle (with handle: prefix) or id is used to match existing coupon within site, when codes are not unique.
// #### Compounding Strategy
// Optional `compounding_strategy` for percentage coupons, can take values `compound` or `full-price`.
// For amount coupons, discounts will be always calculated against the original item price, before other discounts are applied.
// `compound` strategy:
// Percentage-based discounts will be calculated against the remaining price, after prior discounts have been calculated. It is set by default.
// `full-price` strategy:
// Percentage-based discounts will always be calculated against the original item price, before other discounts are applied.
// ### Line Item Options
// #### Period Date Range
// A custom period date range can be defined for each line item with the `period_range_start` and `period_range_end` parameters. Dates must be sent in the `YYYY-MM-DD` format.
// `period_range_end` must be greater or equal `period_range_start`.
// #### Taxes
// The `taxable` parameter can be sent as `true` if taxes should be calculated for a specific line item. For this to work, the site should be configured to use and calculate taxes. Further, if the site uses Avalara for tax calculations, a `tax_code` parameter should also be sent. For existing catalog items: products/components taxes cannot be overwritten.
// #### Price Point
// Price point handle (with handle: prefix) or id from the scope of current subscription's site can be provided with `price_point_id` for components with `component_id` or `product_price_point_id` for products with `product_id` parameter. If price point is passed `unit_price` cannot be used. It can be used only with catalog items products and components.
// #### Description
// Optional `description` parameter, it will overwrite default generated description for line item.
// ### Invoice Options
// #### Issue Date
// By default, invoices will be created with a issue date set to today. `issue_date` parameter can be send to alter that. Only dates in the past can be send. `issue_date` should be send in `YYYY-MM-DD` format.
// #### Net Terms
// By default, invoices will be created with a due date matching the date of invoice creation. If a different due date is desired, the `net_terms` parameter can be sent indicating the number of days in advance the due date should be.
// #### Addresses
// The seller, shipping and billing addresses can be sent to override the site's defaults. Each address requires to send a `first_name` at a minimum in order to work. Please see below for the details on which parameters can be sent for each address object.
// #### Memo and Payment Instructions
// A custom memo can be sent with the `memo` parameter to override the site's default. Likewise, custom payment instructions can be sent with the `payment_instrucions` parameter.
// #### Status
// By default, invoices will be created with open status. Possible alternative is `draft`.
