How do I pass a fully formed purchase units array to OrderRequestBuilder

[zerocarbthirty]

Hello,

Because PayPal broke something in their API our integration stopped working last week. We had been using paypal-checkout-sdk which is old and deprecated but it still worked until last week.

Anyhow I am trying to integrate PayPal-PHP-Server-SDK into our application and I am having the hardest time figuring out how I can just send an entire fully formed purchase_units array to the builder. I cannot really figure out what the builder wants here:

PurchaseUnitRequestBuilder::init(
                                   AmountWithBreakdownBuilder::init(
                                       'USD',
                                       '1.00'
                                   )->build()
                               )->build()

$purchase_units = array("intent" => "CAPTURE",
	"purchase_units" =>
        array(
        	0 => array(
                	"reference_id" => $service,
                        "description" => $ppService,
                        "amount" => array(
                                 "currency_code" => "USD",           
                                 "value" => $ppTotal,
                                 "breakdown" => array(
                                 	"item_total" => array(
                                                    "currency_code" => "USD",
                                                    "value" => $ppdue),
                                        "tax_total" => array(
                                                   "currency_code" => "USD",
                                                    "value" => $ppTax)
                                        ),
                                ),
	                            "items" => array(
	                            	0 => array(
                                    	"name" => $ppService,
                                    	"description" => Item 1,
                                    	"sku" => $service,
                                    	"unit_amount" =>
                                        array(
                                            "currency_code" => "USD",
                                            "value" => $up),
                                     "tax" =>
                                        array(
                                            "currency_code" => "USD",
                                            "value" => $ppTax),
                                    "quantity" => $qty,
                                    "category" => "DIGITAL_GOODS"
                                    )
                                )
                            )
                        ),
                        "application_context" =>
                            array(
                            "cancel_url" => "https://www.widgetsrus.com/step-2",
                            "return_url" => "https://www.widgetsrus.com/step-3",
                            "brand_name" => "Widgets R Us",
                            "shipping_preference" => "NO_SHIPPING",
                            "user_action" => "PAY_NOW"
                        )
                );

We'd really like to just keep using the same purchase_units definition that we've been using for a decade or so.

Any thoughts?

@zerocarbthirty Looking at the Documentation for the SDKs, you should be able to do something like this:
